About the SSP 7.1
The SSP 7.1 is a 7.1 channel surround sound processor with four digital inputs and one analog input. A variety of selectable listening modes can be changed to match the source format.
The unit can accept 2 channel analog signals, as well as digital pulse code modulation (PCM) signals, and output them through various matrix decoding mode options for use in 5.1 to 7.1 system configurations.
The SSP 7.1 can decode and process licensed, branded digital source formats from Dolby® Digital ^1 and DTS ^2 , in their originally encoded formats. These include:
• Dolby Digital 2/0
• Dolby Digital 2/0 Surround
• Dolby Digital 5.1
• Dolby Digital Surround EX ^™1
• DTS 2-channel
• DTS Digital Surround ^2
• DTS 96/24 ^2
• DTS-ES ^2 Matrix 6.1
• DTS 96/24 ES Matrix 6.1
• DTS-ES Discrete 6.1
SSP 7.1 Features
Advanced control and configuration — The SSP 7.1 Setup and Control Software provides additional configuration options beyond those available through front panel control.
Emulate and Live modes for configuration — The control program can be used in Emulate mode to create an SSP 7.1 configuration. The modifications can be saved and applied to the unit when a connection is established. In Live mode, the changes are made directly to the unit.
Four digital audio inputs — The unit accepts four digital inputs through two optical (TOSLINK®) digital inputs and two S/PDIF coaxial (RCA) digital inputs.
One analog input — The unit accepts one balanced/unbalanced analog input on a 5-pole captive screw connector.
Configurable analog input — Input 5 accepts balanced or unbalanced stereo analog inputs and can be configured to accept one or two balanced or unbalanced mono inputs through a captive screw connector. The mono source can be left, right, or a mix summed of the two.
Automatic surround sound format detection and decoding — The SSP 7.1
automatically detects the format of the incoming audio signal, and then applies the user-defined decoding so that signals are sent to the appropriate outputs.
Input source surround sound format indicator — The appropriate LED indicator illuminates to indicate the incoming format of the selected input source, whether Dolby Digital, DTS, PCM, or two-channel analog.
Dolby Digital and DTS playback — The unit is able to decode and process source format from Dolby Digital and DTS, in their originally encoded formats.
Matrix decoding — The surround sound processor can decode stereo signals to produce multichannel output.
Downmix multichannel source formats — Downmixing produces a mixed stereo or mono channel with an additional option to redistribute the downmixed signal to all channels.
Front panel audio level adjustment with LED level and analog clip indication —
Provides overall output volume adjustment for all outputs as well as adjustment of input level for the analog input. Accompanying LEDs display input gain level, and a dedicated LED indicator illuminates red when analog clipping has occurred.
Multiple listening modes — Not all listening modes are compatible with certain input signals. The listening mode depends not only on the format of the source material but also on the speaker configuration of the setting. Only those listening modes that are compatible for a given input are available for that signal. The SSP 7.1 comes with factory default listening modes that have been matched to the source format to take into account source format and speaker configuration.
Listening mode override — Listening mode override customizes the listening mode to the needs of the source format, speaker configuration, the venue, and the personal preferences of the listener. Selections made through the front panel can be further refined by the SSP 7.1 Setup and Control Software.
This feature can be used to associate a specific listening mode with each input type, allowing the user to switch quickly to the listening mode that suits each input type for a given room configuration and the individual user preferences.
Test signals for setup and calibration — The SSP 7.1 generates test signals, including band-limited Dolby noise and full-bandwidth pink noise, to facilitate calibration of sound pressure levels from all speakers, and to fine-tune the interaction of a speaker with the acoustical environment. The SSP 7.1 also offers the option to use an external source for test signals, which can then be directed to any speaker, or all speakers in sequence.
Speaker compensation delay — The signal to each output channel can be individually delayed so that the sound from all speakers is synchronized when it reaches the listener.
Lip sync offset — This feature delays an audio signal so that it is resynchronized with a video signal that has been delayed by video processing. The offset can be applied to each input channel independently.
Equalization — Nine bands of parametric EQ are available to enhance tone, compensate for differences in individual speaker output, and adjust frequency response for a given acoustic environment.

NOTE: On earlier models of the SSP 7.1, the Surround Output Channels are labeled Side.
① AC power input — Use an IEC power cable to connect the processor to a 100 - 240 VAC, 50 - 60 Hz, power source.
② Audio inputs — The SSP 7.1 accepts four digital inputs and one analog input.
- Inputs 1 and 2 accept digital signals through S/PDIF optical cables.
- Inputs 3 and 4 accept digital signals through S/PDIF coaxial cables.
- Input 5 accepts a balanced or unbalanced, stereo or mono, analog input through a 5-pin captive screw connector.
The following diagram shows the correct wiring for different analog input signals.
Unbalanced Stereo Input
Balanced Stereo Input
Unbalanced Mono Input
Balanced Mono Input (high impedance)
Figure 2. Wiring for Analog Input (Input 5)
NOTES: • The length of the exposed wires in the stripping process is critical. The ideal length is 3/16 inches (5 mm). Any longer and the exposed wires may touch, causing a short circuit between them. Any shorter and the wires can be easily pulled out even if tightly fastened by the captive screws.
- Do not tin the wires. Tinned wire does not hold its shape and can become loose over time.
For more information about input formats, see "Front Panel Features and Operations" on page 6 and the "Source Formats" section on page 61.
③ Audio outputs — Outputs are balanced or unbalanced line level analog signals that feed into multichannel amplifiers for configurations up to 7.1 surround sound. For more information about Speaker Setup, see page 13.
Figure 3. Audio Outputs
Individual output settings are configured through the SSP 7.1 Setup and Control Software (see page 30) or SIS commands (see page 86):
Mono — Output is through the center channel only but can be reconfigured to be output through the left and right front channels. In the absence of a center channel, mono is also output through the left and right front channels.
2-channel (stereo) — Only the front left and front right channels are used.
2.0 to 2.1 surround configurations — Audio is output through front left and front right channels with (2.1) or without (2.0) a subwoofer.
3.0 to 3.1 surround configurations — Audio is output through front left, front right, and center channels with (3.1) or without (3.0) a subwoofer.
4.0 to 5.1 surround configurations — Audio is output through a combination of front left and right, left and right surround, center and subwoofer channels.
6.0 to 6.1 surround configurations — Adds a back channel to 5.0 or 5.1 configurations. The back left channel receives the sixth channel information and serves as the center back speaker in this configuration.
7.0 to 7.1 surround configurations — Both the back left and right channels are active. Listening modes designed for 6.1 channel outputs pass the same signal to both the back left and right channels. Listening modes designed for 7.1 channel outputs pass separate signals to each channel to produce a stereo back sound effect.
For more information about speaker configuration and output formats, see the "Listening Mode Options and Usage" section on page 66.
④ RS-232 port — The SSP 7.1 can be configured using the SSP 7.1 Setup and Control Software or SIS commands, using this 3-pole captive screw connector (or the 2.5 mm Tip Ring Sleeve (TRS) mini jack plug on the front panel).
For more information about the SSP 7.1 Setup and Control Software, see page 22. For more information about SIS commands, see page 78.

Figure 4. SSP 7.1 Front Panel Features
⑤ Configuration port — The SSP 7.1 can be configured using Extron Simple Instruction Set™ (SIS™) commands through this 2.5 mm Tip Ring Sleeve (TRS) mini jack plug (or through the 3-pole captive screw connector on the rear panel). For more information about SIS commands, see page 78.
NOTE: Both the rear panel RS-232 port and the front panel configuration port can be used at the same time. Neither has precedence. The SSP 7.1 responds to commands in the order received.
Source Format
⑥ Input source format indicator — The bank of four LEDs identify the format of the audio input.
- Dolby Digital (D): Dolby Digital 2/0, Dolby Digital 2/0 Surround, Dolby Digital 5.1, or Dolby Digital Surround EX.
- DTS: DTS 2-Channel, DTS Digital Surround, DTS 96/24, DTS-ES Matrix 6.1, DTS 96/24 ES Matrix 6.1, or DTS-ES Discrete 6.1.
• PCM: 2-channel uncompressed digital source format.
NOTES: • A digital signal that does not have a supported sampling rate or is compressed PCM is considered an unrecognized signal and is muted.
- When a DVD player is paused during playback, the SSP 7.1 may or may not continue to receive source format information from the DVD player. Some players continue to send the same source format information in a loop, allowing the SSP 7.1 to retain the previous settings. Other DVD players completely disconnect the signal from the SSP 7.1 (unlocked state), so that the active input blinks as if there is no connection present. The remainder of DVD players change the source output to PCM without an actual signal being sent (digital silence). During digital silence, the PCM LED lights but the 2-CH source LED does not.
2-Channel (2-CH):
• Any source coming through analog input 5.
- If a PCM digital signal is present on any of the digital inputs, both the PCM and the 2-CH LEDs light.
- If a Dolby Digital 2/0 or Dolby Digital 2/0 Surround source is present, both the D and the 2-CH LEDs light.
- If a DTS 2-Channel source format is present, both the DTS and 2-CH LEDs light.
To understand more about source formats, see page 61.
Mode Override Selection
⑦ Mode Override selector — The SSP 7.1 has a wide range of listening modes, although not all listening modes are compatible with every source format. The speaker configuration of the system may further limit which listening mode is available for a source format. Other factors, such as the room layout and listener preferences, may also influence the listening mode selection.
The SSP 7.1 has default listening modes associated with each source format. The front panel provides the user with a limited set of Mode Override settings. These can change the listening mode that is associated with a specific combination of source format and input. The override selections can be further defined using the SSP 7.1 Setup and Control Software, or SIS commands.
The new, user-defined listening mode continues to be associated with that source format until Mode Override is used, again, to associate a new listening mode with the source format. To select a listening mode:
- Use the push button to toggle through the available listening modes. When no mode override is chosen, none of the LEDs light, indicating that a user-defined listening mode is in use. Otherwise, one of the four LEDs shows the current selection.
- Release the button when the desired LED is lit to select that listening mode. If a listening mode is not an available option for the current input source, toggling the button skips that mode and goes to the next available mode.
- If required, further define the selection using the SSP 7.1 Setup and Control Software Listening Mode Setup Tab (page 45).
The mode override selections that are available through the front panel are:
- Downmix (DOWNMIX) — Downmixes any multichannel source format (digital inputs only). It also downmixes a 2-channel source format, if the listening mode is set to mono.
It is further defined from the Setup and Control Software (see page 48). Options include:
- Stereo, output on left front and right front channels.
- Mono, output to center channel only or to left and right front channels equally.
- Dolby Pro Logic II/IIx (PL II/IIx) — uses Dolby Pro Logic II or Dolby Pro Logic IIx surround processing technology.
- Dolby Pro Logic II extends 2-channel sources to output 5.1 channels. It can be further defined by control software as either Dolby Pro Logic II Movie (default) or Dolby Pro Logic II Music.
- Dolby Pro Logic IIx extends 2-channel sources to output 6.0 to 7.1 channels (depending on the speaker setup). It can be further defined by control software as either Dolby Pro Logic IIx Movie or Dolby Pro Logic IIx Music.
- Dolby Pro Logic IIx also provides an extended surround option for multichannel sources such as DTS Digital Surround or Dolby Digital 5.1.
- DTS Neo:6 (DTS NEO:6) — Uses DTS Neo:6 surround processing technology to extend analog or 2-channel digital source formats (PCM, Dolby Digital 2/0, Dolby Digital 2/0 Surround, DTS 2-Channel) to output up to 7.1 channels. It is further defined by control software as either DTS Neo:6 Cinema (default) or DTS Neo:6 Music.
- To All (TO ALL) — Distributes a mono or 2-channel source to all applicable channels.
• Mono sources are sent to all available output channels, including center.
- 2-channel sources are sent to all stereo pairs only.
- Multichannel sources are downmixed and output to Mono to All or Stereo to All, as defined by the user.
- Digital or analog stereo sources may be output to Mono to All or Stereo to All, as defined by the user. If Mono to All is selected, the signal is downmixed to mono before being output to all channels.
NOTE: If an analog mono source is on the left channel, Stereo to All listening mode outputs only to the left channels of available stereo pairs. A right channel analog mono source is output only to the right channels of available stereo pairs.
When used in conjunction with the Input buttons, the Mode Override button is used to mute all outputs (see page 10).
The Mode Override button is used to perform a complete system reset (see "Complete System Reset" on page 10).
To learn more about listening modes, see "Listening Mode Options" on page 66. To learn how listening modes depend on both source format and speaker configuration, see "Source Formats and Listening Modes with Different Speaker Setups" on page 75.
Input Selection
Figure 5. SSP 7.1 Input Selection Switches
⑧ Input selections — Push one of the buttons to select between five possible audio inputs. The LED next to the currently active input lights.
In conjunction with the Mode Override button, the input buttons are used to mute all outputs (see page 10).
The input buttons are also used to enable or disable front panel security lockout (executive mode). For more information, see page 12.
In conjunction with the volume adjust knob, the analog input (Input 5) is used to set analog input gain level for the analog source (see page 11).
The SSP 7.1 accepts four digital inputs and one analog input (see Rear Panel Features on page 4):
- Inputs 1 and 2 accept digital signals through S/PDIF optical cables. The optical cable supports TOSLINK or TOSLINK-compatible optical connectors that conform to IEC-958, S/PDIF standards.
- Inputs 3 and 4 accept digital signals through S/PDIF coaxial cables.
All four digital inputs accept 16-24 bits PCM audio at 32, 44.1, 48, 88.2, and 96 kHz sample rates. They support Dolby Digital and DTS source formats.
NOTE: For digital inputs, if there is no valid clock signal at the input and no lock is achieved, the LED associated with the source blinks twice per second.
- Input 5 accepts a balanced or unbalanced analog input through a 5-pin captive screw connector. The unit can be configured to accept:
- A stereo signal
• A mono signal from the right channel
• A mono signal from the left channel
• A mixed sum of right and left channels
The input can also be selected using the SSP 7.1 Setup and Control Software (see Input Source on page 26).
Mute Output
When the mute state is enabled, all channels are muted simultaneously. To toggle between mute and unmute:
- Press and hold the active input button (the button next to the LED that is lit).
- While still holding the active input button, press the Mode Override button.
When the mute state is enabled, the individual LEDs of the Volume Adjustment LED bar light in sequence from the top down. This scrolling down pattern repeats while the mute state persists.
NOTES: • Selecting another input button while the mute function is enabled, disables the mute function.
- Adjusting the volume control encoder to change the volume (or the analog input gain) settings while the mute function is enabled, disables the mute function and increases (or decreases) the volume (or gain) from its previous setting.
- If SIS commands have been used to mute a specific channel, muting and unmuting all channels also unmutes the channel that was specifically muted. It does not remain in its previously muted state.
All channels can also be muted using the SSP 7.1 Setup and Control Software (see Master Volume and Mute on page 29).
Complete System Reset
The SSP 7.1 has three levels of System Reset.
Standard system reset — All parameters that can be adjusted by the control program are reset to default.
Factory reset — In addition to resetting all the parameters of the standard system reset, the baud rate for communicating with the computer is also reset.
Complete system reset — In addition to resetting all the parameters of the factory reset, the firmware is reset to the factory-installed version.
The standard and factory resets are performed using SIS commands (see the System Reset SIS commands on page 94).
To perform a complete system reset, hold the Mode Override button while shutting off and restoring power.
Volume Adjustment
⑨ Volume adjust knob and LED bar or Analog input gain level control and LED bar — Use the rotary encoder to adjust the output volume from 0 (-100 dB) to 100 (0 dB). The default setting is 50 (-50 dB).
The degree to which the volume is incremented or decremented for each step the encoder is turned, depends on the current volume setting (see the last column in the table below).
As the volume increases or decreases, the LED bar lights to indicate the current volume range, as shown in the table below. As the volume is increased or decreased within a volume range, the top LED to be lit flashes once. If the knob is turned past maximum volume, all 8 LEDs flash, for as long as the knob continues to be turned.
| Volume steps for each LED (dB) | LEDs lit Increment | (dB/knob step) |
| >0 All LEDs blink if user tries to turn knob further | ||
| 0 All 8 LEDs on | 1 | |
| -4 to -1 All 8 LEDs on | ||
| -9 to -5 Bottom 7 LEDs on | ||
| -14 to -10 Bottom 6 LEDs on | ||
| -19 to -15 Bottom 5 LEDs on | ||
| -29 to -20 Bottom 4 LEDs on 2 | ||
| -49 to -30 Bottom 3 LEDs on | 4 | |
| -69 to -50 Bottom 2 LEDs on | ||
| -99 to -70 Bottom LED on | 5 | |
| -100 All LEDs off | ||
Table 1. Volume Level and Lighting of LED Bar
The volume can also be controlled using the SSP 7.1 Setup and Control Software (see Master Volume and Mute on page 29).
Analog Input Gain Adjustment
Alternatively, the rotary encoder controls the gain level of the analog signal on input 5. Analog input gain is adjustable from 0 dB (fully counterclockwise) to +24 dB (fully clockwise).
To adjust input gain, press and hold the Input 5 button, while turning the rotary encoder.
NOTES: • If the gain level is too high, clipping may occur. When clipping occurs, the red LED above the Input 5 button lights.
- When using Mono or Mono to All listening mode, the left and right signals are summed (in the digital domain), which can cause a boost in level up to 6 dB. This type of clipping does not cause the clip indicator LED to light but is audible. If using a mono mode, it is recommended that the input gain be reduced by 9 dB below clipping to prevent clipping from occurring.
The LED bar lights from the bottom up to indicate the current gain level. No LEDs lit indicates no gain (0 dB, or unity gain); all the LEDs lit indicates maximum gain (24 dB). Each solidly lit LED represents 3 dB. A slowly blinking LED indicates an additional 1 dB or a quickly blinking LED indicates an additional 2 dB:
| Number of LEDs lit solidly | Gain (dB) | ||
| No Blinking Slow | Blinking Fast Blinking | ||
| 8 24 - - | |||
| 7 21 22 23 | |||
| 6 18 19 20 | |||
| 5 15 16 17 | |||
| 4 12 13 14 | |||
| 3 9 10 11 | |||
| 2 6 7 8 | |||
| 1 3 4 5 | |||
| None No LEDs | lit; 0 dB 1 2 | ||
Table 2. Gain level and lighting of LED bar
The analog input gain can also be controlled using the SSP 7.1 Setup and Control Software (see Master Volume and Mute on page 29).
Front Panel Security Lockout (Executive Mode)
When the front panel is locked, the user cannot make any changes from the front panel (except disabling the security lockout). If the user attempts to make changes with the front panel locked out, all the input LEDs flash simultaneously. The lockout does not block changes made using SIS commands or the SSP 7.1 Setup and Control Software. To lock out the front panel:
- Press and hold the active input button (the button next to the LED that is lit).
- While holding the active input button, press and hold any other input button. All the LEDs blink in ascending order (from 1 to 5) and then the active input button lights.
- The front panel is unlocked in exactly the same way. All the LEDs blink in descending order (5 first and 1 last) and then the active input button lights.
This feature can also be set, using the SSP 7.1 Setup and Control Software (see Front Panel on page 52).
Setup
This section provides background information about arranging speakers in a room and about some of the settings that can be adjusted by the SSP 7.1 Setup and Control Software. Extron strongly recommends that the control software is used to make any configuration changes to the SSP 7.1. (See "Setup and Control Software" on page 22).

Speaker Setup
The following figures show the recommended speaker placement, relative to the listener, for a five, six, or seven speaker system and for subwoofer placement.
NOTE: All speakers should be angled inwards so that they face towards the listener.

Abbreviations
C = Center CB = Center Back (Six Speaker Setup only) L = Left LB = Left Back (Seven Speaker Setup only) LS = Left Surround R = Right RB = Right Back (Seven Speaker Setup only) RS = Right Surround SW = Subwoofer
Figure 9. Subwoofer Placement
NOTES: • To produce a good bass response from the subwoofer, it should be located at the front of the room, somewhere between either corner and a point about one third of the way along the front wall.
- The output channel used for the Left Back speaker (in 7.1 configurations) is also used for the Center Back speaker (in 6.1 configurations).
Bass Management
Low frequency sound is usually better handled by the subwoofer. Bass management creates the subwoofer channel by separating the low frequency information from the satellite speakers at a user-defined crossover point. This is summed with the Low Frequency Effects (LFE) information encoded in the source format. When no subwoofer is present, subwoofer content is sent to speakers set to Large (excluding the center speaker).
Speaker Size Settings
This feature sets bass management on or off for a particular speaker, defining the frequency range output by that speaker. These settings also enable or disable the subwoofer and set the crossover frequency.
- Left and right front speakers and left and right surround speakers are set in pairs.
• The center speaker is set as an individual speaker. - Back speaker(s) can be set as a single speaker or as a pair of speakers, depending on the system configuration.
Small — Bass management is on for that speaker. The output to each speaker (other than the subwoofer) is limited to frequencies above the crossover frequency. By default, center and surround speakers are set to Small.
Large — Bass management is off for that speaker. The full range of audio frequencies from the audio source is fed through the output of each individual channel. This may be set in the absence of a subwoofer. By default, front speakers are set to large.
When there is no subwoofer, all speakers set to Large (except the center channel) receive the summed audio from the filtered low frequency signals of speakers set to Small.
None — This mode prevents any signal from being sent to that output channel. It is not an option for front speakers.
One Small Speaker, Two Small Speakers, One Large Speaker, Two Large Speakers, or None (Surround back speakers only) — This mode determines whether the audio output channels for the back speaker(s) are passed to the left back and right back (in 7.1 setups) or to the center back (in 6.1 setups).
If either of the one speaker options are chosen, the highest possible number of outputs is 6.1 speakers. In this case, the output is directed to the left back channel output.
If either of the two speaker options are chosen, the SSP 7.1 is able to output up to 7.1 channels. Source formats with discrete or matrix mixed 6.1 encoded channels output the surround back channel signal equally to the left and right back channels. Dolby Pro Logic IIx and DTS Neo:6 listening mode options output a stereo signal to the left and right back channels.
NOTE: If the surround speakers have been disabled, the back speaker options are also disabled.
By default, the back speaker is set to None, which prevents a signal from being output on the back channel(s).
Subwoofer — This option allows the subwoofer to be enabled or disabled. When the subwoofer is enabled, the signal contains filtered low frequency signals from speakers set to Small in addition to the LFE signal from the source format. If the subwoofer is absent or disabled, the LFE signal is mixed with the bass information of all speakers in the system that are set to Large, except the center speaker.
NOTES: • When the surround and back speakers are set to None, all multichannel input signal formats are downmixed and output on all remaining channels.
- In addition, in the absence of a center channel, mono signals are output equally between the front left and front right channels. Multichannel sources are downmixed to all remaining channels, but Mono to All and Stereo to All options are disabled. Choosing Mono listening mode first downmixes the multichannel source and outputs it to the front left and right channels equally as a dual mono signal.
Crossover Frequency — The crossover frequency sets the boundary below which the low frequency signals from designated output channels are incorporated into bass management. Low frequency signals are only taken from speakers that have been set to Small (see "Speaker Size Settings" on page 15). The bass management signal is passed to the subwoofer (if present) or speakers that have been set to Large (except for the center speakers) if a subwoofer is not present.
The crossover frequency can be adjusted within the range of 40 Hz to 250 Hz, with a default setting of 100 Hz. Speakers set to Small (see "Speaker Size Settings" on page 15) play only signals above the set frequency.
Speaker Delay Settings
There are two different signal delays that compensate for different needs.
Compensation delay — In a room where speakers are not equidistant from the listener, sound from the closest speaker reaches the listener before sound from the farthest speaker. This feature allows the user to enter the speaker distance value for each speaker output channel. The application calculates the delay values for the closest speakers, up to 100.0 ms, so that all audio arrives at a central location (the "sweet spot") at the same time.
Lip sync offset — Video delays occur due to changes in programming from a source (TV, Cable, Satellite, or DVD player) and also if the video signal has to be processed through another device between the source and the display. The lip sync offset feature allows the user to delay the audio sent to all output channels so that video and audio output are synchronized.
Since each source may need a different level of compensation, the lip sync offset for each input is independently adjustable from 0.0 to 100.0 ms. Apply lip sync offset to the audio until what is heard matches up with what is seen on the display.
To configure these settings using the SSP 7.1 Setup and Control Software, see "Speaker Delay Tab" on page 32.
Test Signals
Test signals are used during setup to calibrate the level for each channel and to ensure proper connection between the individual output channels of the SSP 7.1 and the line level input channels of an audio signal processor, a receiver with built in amplifier, or a stand alone amplifier that powers the loudspeakers.
The three options for test signal source are pink noise, Dolby noise, and an external source. By default, the test signal is switched off.
Pink Noise — Pink noise is a random signal, generated by the SSP 7.1, with all audio frequencies present. It provides equal energy per octave to provide a flat response over all frequencies. The main purpose of pink noise is to calibrate the interaction of a speaker with its environment.
Dolby Noise — Dolby noise provides a bandpass-filtered noise, centered at 750 Hz with a 12 dB/octave roll off. This signal is also generated by the SSP 7.1 and is used to set speakers to the same level when calibrating the room.
Active Input — This option requires an external test signal source, such as a signal generator, played through the selected input source. Generally, this is a device with an analog signal output, with the SSP 7.1 analog input used as the active input.
Signal generators are usually used to test specific decoding mode outputs. When the External Source option is chosen, the speakers that receive the test signal can be specified.
To calibrate speaker output, use any of these test signals with the SSP 7.1 Setup and Control Software, see Test Signals on page 36.
Output Channel Trim Settings
This control adjusts the output channel trim level for each output channel to match the levels to the unique needs of any listening environment. The level can be adjusted within the range from -24 dB to +12 dB. The default setting for each speaker is 0 dB. See Output Trim on page 39 for more information.
Listening Mode Settings
The SSP 7.1 provides a range of settings that refine the sound distribution for each listening mode, depending on the decoding mode that has been selected.
Dolby Pro Logic II or IIx Music
Dimension control — This feature alters the ratio of L+R to L-R for two-channel input signals, which adjusts the sound field towards the front or towards the back. The available settings are Front, Neutral, or Back. The default setting is Neutral.
Center width control — Pro Logic decoding produces a single center signal that comes from the center speaker. If there is no center speaker, a “phantom” center image is produced that is split between the right and left speakers.
If right, left, and center speakers are present, center width control allows variable adjustment of the center image so that is heard only from the center speaker, only from the right and left speakers, or from all three speakers in varying degrees.
There are up to eight different settings, with each corresponding to a specific calculation angle ( ). When the setting is 0, the sound comes from the center speaker, when the setting is 7, the sound is from the L/R speakers. The default setting is 3.
| Control Position Calculation Angle (Φ) | C Level (dB) L/R | Level (dB) |
| 0 0.0 0.0 Off | ||
| 1 20.8 -0.6 -12.0 | ||
| 2 28.0 -1.1 -9.6 | ||
| 3 36.0 -1.8 -7.6 | ||
| 4 54.0 -4.6 -4.8 | ||
| 5 62.0 -6.6 -4.1 | ||
| 6 69.2 -9.0 -3.6 | ||
| 7 90.0 Off -3.0 |
NOTE: The level of the center speaker (C Level) is related to cosine . The level of the left and right speakers (L/R Level) is related to sine .
Panorama control — This feature extends the center width control, so that all or part of the center image can be heard from the surround speakers for a “wraparound” effect. The feature may be On or Off. The default setting is Off.
DTS Neo:6 Music or Cinema
Center image control — The center image control varies the amount of attenuation applied to the left and right channel information of the input source that is used for creating the output center channel effects. When it is set to 0, the mixed input signal information, intended for use in creating the center output channel of the DTS Neo:6 listening modes, is filtered back to the front left and right output channels. This creates the effect of spreading the centralized audio signal across all three front output channels. When this control is set to 10, the matrixed information intended for the center output channel effects is fully attenuated, allowing the center channel to create a more centralized effect from the front channels.
The default setting for DTS Neo6: Music is 3. The default for DTS Neo6: Cinema is 10.
Dynamic Range Compression Control
This control is available only with Dolby Digital and DTS source formats that have a Dynamic Range Compression flag.
This control adjusts the gain applied to Dolby Digital or DTS listening modes to compress the signal outputs during the decoding process. The three possible settings are None, Minimum, and Maximum. The default setting is None.
Off — The signal is uncompressed and is played with the full original dynamic range.
Minimum — The audio is partially compressed. In this mode, the volume of the loudest passages is reduced but quieter passages are kept at their original level. This level is recommended for normal listening.
Maximum — The audio is fully compressed. This level is recommended for environments where loud audio is not permitted.
NOTE: DTS source formats have only two states (On and Off) for dynamic range compression. Therefore, Minimum and Maximum both apply the same dynamic range compression.
Tone Controls
These controls regulate the bass and treble settings for the system. To adjust the bass or treble tone controls, see Tone Controls on page 27.
Bass — The bass control regulates the amount by which low frequency signals are boosted or cut (see figure below). It is applied to outputs for all speakers, including the subwoofer.
line
| Frequency (Hz) | Level (dB) | | -------------- | ---------- | | 20 | -10 | | 30 | -8 | | 60 | -6 | | 100 | -4 | | 200 | -2 | | 300 | 0 | | 600 | 0 | | 1k | 0 | | 2k | 0 | | 3k | 0 | | 6k | 0 | | 10k | 0 | | 20k | 0 |Figure 10. Bass Range
Treble — The treble control regulates the amount by which high frequency signals for all speakers, except the subwoofer, are boosted or cut (see figure below).
line
| Frequency (Hz) | Level (EPA) | | -------------- | ----------- | | 20 | 0 | | 30 | 0 | | 50 | 0 | | 100 | 0 | | 200 | 0 | | 300 | 0 | | 500 | 0 | | 1K | -2 | | 2K | -4 | | 3K | -6 | | 5K | -8 | | 10K | -10 | | 20K | -12 |Figure 11. Treble Range
Volume Output
This control sets the volume of the audio output through all channels, globally, to either Variable (the default value) or Fixed.
Variable — When the Volume output is set to Variable, the volume can be attenuated using the front panel knob, the SSP 7.1 Setup and Control Software, or SIS commands.
Fixed — The Fixed option sets the volume to the current attenuation level. Likewise, all the Output Channel Trim levels (see Output Trim on page 39) are fixed at the values they had immediately before the Volume Output was set to Fixed.
When Fixed is selected, the volume cannot be adjusted through the front panel knob, by the SSP 7.1 Setup and Control Software, or by SIS commands.
Equalization
Parametric equalization (or parametric "EQ") allows the control of amplitude of each band, center frequency (which can be shifted, widened, or narrowed) and bandwidth (which may be labeled "Q" for Quality). Parametric equalization is used to improve the audio output in a specific acoustic environment.
Resonance reduction — Reduces the level at specific frequencies that are too loud.
Speaker compensation — Compensates for peaks and dips in individual speaker output response.
Tonal enhancement — Increases the level of frequencies within a broad or narrow range that sound too quiet.
Setup and Control Software
The SSP 7.1 Setup and Control Software provides an intuitive, easy to operate, graphical user interface that allows the user to configure the audio system quickly and efficiently. It provides more options than the front panel. As selections are made, only the options that are available for the current configuration are displayed by the software. Extron strongly recommends using the SSP 7.1 Setup and Control Software for all configuration.

By default, the Installer program creates a C:\Program Files\Extron\SSP7.1 folder to contain the SSP 7.1 Setup and Control Software. An icon may also be placed on the Windows desktop.
NOTE: Updating the SSP 7.1 Setup and Control software may also require a more recent version of the firmware to be installed (see Firmware Updates on page 56).
If the new software detects an old version of the Firmware, a pop-up window informs the user that the firmware should be updated and also prompts the user to save the existing configuration for reloading onto the SSP 7.1 when the new firmware has been installed.
When the firmware has been updated, open the SSP 7.1 software in Emulate mode (see below) and open the saved configuration. Click on the Live button and, when the Synchronize with Device pop-up appears, select Push the data from this configuration to device, overwriting any data currently in it. option.
Live and Emulate Modes
The SSP 7.1 Setup and Control Software offers a choice of Live or Emulate mode. In Live mode, any changes made using the software directly affect the configuration of the sound processor.
In Emulate mode, the computer is not connected to the sound processor and any changes you make must be saved as an *.esp file. The file can be used later to update the configuration of the sound processor when the computer is directly connected to the SSP 7.1 in Live mode.
You may choose between Live and Emulate modes either when the program first starts up in the Connect to Device? dialog box (see page 24) or, when the main program window is running, using the Live and Emulate buttons in the top right corner (see the figure at right). You can also toggle between the two modes, by using the F5 and F6 keys or clicking on Connect... (F5) or Disconnect (F6) under the Device menu (see page 52).
When you switch from Emulate to Live mode, you are prompted to synchronize the settings in the SSP 7.1 Control and Setup Software with the current
configuration in the SSP 7.1 device. Select Push to overwrite the configuration in the device with the software settings made in Emulate mode, or select Pull to overwrite the software settings with the configuration in the device.

Speaker Setup Tab
After completing the Main tab, the next tab is Speaker Setup, which is the first tab to allow system configuration that is not available from the front panel. The Speaker Setup tab provides access to four second-level tabs (Speaker Configuration, Speaker Delay, Testing & Output Trim, and Speaker Equalization).
Speaker Configuration Tab
Figure 18. Speaker Configuration Tab
Speaker size
Speaker size determines whether or not bass management applies to that speaker. For more information about bass management and speaker size, see pages 15 and 16.
Speaker size settings — All the buttons in a single column offer mutually exclusive choices. Only one selection can be made from each column. For example, front speaker size must be set to either 2 Large or 2 Small. It cannot be set to both values or neither value.
Figure 19. Speaker Size Settings
- Left and right front speakers and left and right surround speakers are set in pairs.
- The center speaker is set as an individual speaker.
- Back speaker(s) can be set as a single speaker or as a pair of speakers, depending on the system configuration.
- The subwoofer can be set to Present or None.
Small — Bass management is on (see page 15).
Large — Bass management is off (see page 16).
None — No signal is sent to the output for that channel, effectively removing the speaker from the current configuration. It is not an option for front speakers (see page 16).
One Small Speaker, Two Small Speakers, One Large Speaker, Two Large Speakers, or None (Back speakers only) — These options determine whether the audio output channels for the back speakers are output to the left back and right back (in 7.1 setups) or to the center back (in 6.1 setups). For more information, see page 16.
Subwoofer — This option allows the subwoofer to be enabled or disabled (see page 16).
Crossover — The crossover frequency sets the boundary below which the low frequency signals from designated output channels are incorporated into bass management (see
page 16). The crossover frequency is adjustable using the drop-down menu.
• From 40 - 80 Hz, increment and decrement in 5 Hz steps
• From 80 - 150 Hz, increment and decrement in 10 Hz steps
• From 150 - 250 Hz, increment and decrement in 25 Hz steps
Speaker configuration
The speaker configuration is displayed in a graphics box that is very similar to the graphics box shown in the Input and Output information bar.
Only the speakers available in the current configuration are displayed.
If the speakers are set to Large, they are represented by large icons, as shown in the figure at right. If the speakers are set to Small, they are represented by small icons.
If the speakers are set to None, they are not available in the current configuration and are not displayed.
If the back speakers are set to 1 Large or 1 Small, the CB speaker, but not the LB and RB speakers, are shown (6.1
setups). If the back speakers are set to 2 Large or 2 Small, the LB and RB speakers, but not the CB speaker, are shown (7.1 setups).
Input and Output information bar
The Input and Output information bar is available from all GUI tabs and is described in detail on pages 28 and 29.
Speaker Delay Tab
After completing the Speaker Configuration tab, configure the Speaker Delay tab.
Figure 20. Speaker Delay Tab
These controls introduce a signal delay for each speaker that has not had its size value set to None. The two main reasons to adjust the signal delay are:
- To compensate for unequal distances between the speakers and the listener, which causes sound from different speakers to reach the listener at different times.
- To compensate for a lack of coordination between the audio and the accompanying video signal.
Speaker distance
When speakers are arranged in a room, there is a central location or "sweet spot" that offers the best listening point. However, even in that central location, the speakers are not necessarily all equidistant from the listener and the sound from the closest speaker reaches the listener before the sound from speakers that are further away.
Speaker distance settings delay the signals going to each individual speaker (from 0 to 100 ms) so that the signals from all the speakers are synchronized and reach the listener simultaneously. The default setting for each speaker is 0 ms.
Speakers that are not available in the current configuration are not displayed. When the back surround is set to one speaker, the right back speaker is unavailable and the left back speaker is renamed center back.
Extron recommends that the SSP 7.1 Setup and Control Software is used to set speaker delays, using either of the following methods.
Two person setup
NOTE: Setting up speaker delays is easier with two people. If only one person is available, the position of the ears of the listener must be marked precisely. A pile of boxes could be used to ensure that the distances are consistently measured to the correct height. Do not try to guess ear positions, as this introduces measurement errors.
- Pick an ideal central location where all speaker output signals converge.
- Use a tape measure to measure the distance from each speaker to the convergence location. Be sure to measure to the same spot from each speaker.
NOTE: Measurements from the speaker must be to the midrange driver in a three-way speaker or from halfway between the tweeter and the woofer in a two-way speaker. Measurements to the convergence locations must be at ear height.
- Click on the Feet (ft) or Meters (m) button to select the units and enter the Speaker Distance values for each speaker (in feet or meters) in the boxes in the SSP 7.1 Setup and Control Software Speaker Delay tab. The up and down (▲) arrows increase the distance in increments corresponding to steps of 0.1 ms (0.12 feet or 0.03 meters). The software automatically selects the farthest speaker and calculates the delay time (in milliseconds) for each speaker.
These values are shown in the Calculated Delay box. The current values are shown in blue, changes (yet to be saved) are shown in orange.

Figure 22. Calculated Delay — Values Applied
NOTE: Users who wish to calculate the delay time for themselves should follow the full procedure shown on page 94 in "Setting Speaker Delay Settings using SIS Commands."
Setup with a Real Time Analyzer (RTA) calibration tool
- Choose an ideal central location on which all speaker output signals converge.
- Place the microphone from the RTA at ear level in the convergence location.
- Play the audio source. This can be an analog source, provided by the RTA.
- Use the Test Signal Output buttons in the Testing & Output Trim Tab (see page 36) to select which speakers are tested and the order in which the speakers are tested.
- Use the RTA to measure the speaker distance (in ms) for each channel.
- In the SSP 7.1 Setup and Control Software Speaker Delay tab, select the milliseconds (ms) button and enter the values for each speaker (in ms) into the boxes. The up and down (♦) arrows increase the distance in increments of 0.1 ms.
- Repeat steps 4 to 6 until the speaker distance has been entered for all available speakers.
NOTE: The maximum allowable distance for the furthest speaker is 100 ms.
- Click the Apply button to save the changes. The new values (previously in orange, see figure 21) are shown in blue as the current values and there are no values displayed in orange (see figure 22).
To retain the original values, click Cancel instead of Apply.
Lip Sync Offset
Lip sync offset compensates for a lack of coordination between the audio and the accompanying video signal. This frequently occurs if the video signal has undergone complex manipulation that can delay it several milliseconds relative to the audio signal.
Since some sources may require more manipulation than others, the lip sync offset is set for each source individually to synchronize the audio for that source with the corresponding video signal.
Enter the appropriate value in the lip sync offset box. This delay is added to every available speaker to resynchronize the video and audio signals.
Input and Output information bar
The Input and Output information bar is available from all GUI tabs and is described in detail on pages 28 and 29.
Testing & Output Trim Tab
After the Speaker Delay tab, configure the Testing & Output Trim tab.
Figure 23. Testing & Output Trim Tab
Several factors can affect the sound level reaching the listener from different speakers. These factors include the distance from the speaker to the listener, slight variations between the output channels of a single amplifier, and variations between the individual speakers. Use the output trim to set the output level of each individual channel to compensate for all these variations and ensure that the sound level reaching the listener is the same from all speakers.
This tab also provides a test signal utility.
Test signals
Test signals are used during setup to calibrate the level of each channel and to ensure proper connection between the individual output channels of the SSP 7.1 and the line level input channels of an audio signal processor, a receiver with built in amplifier, or a stand alone amplifier that powers the loudspeakers.
Selecting test signal source
There are four test signal options (see Test Signals on page 17): Off, Dolby Noise, Pink Noise, or Active Input. They are selected from the mutually exclusive Source Signal Type buttons. By default, the test signal is Off. The Dolby Noise and Pink Noise test signals are generated by the SSP 7.1.
NOTE: The Active Input selection is normally used with an analog source on input 5. The output must be set to Mono to All.
Set the external source to Mono to All using one of these methods.
Listening Mode Preferences Tab
- Select the listening mode Preferences tab (see page 45).
- Select the input channel that is providing the test signal source (1-5).
- For whatever source format the test signal is using, select Mono to All.
- Return to the Testing & Output Trim tab and click on Active Input.
Override Preferences Tab
- Select the Override Preferences tab (see page 48) and select the input source.
- For selectable mode To All choose the override Mono to All.
- On the front panel of the SSP 7.1, use the Mode Override button to select To All
Selecting speakers to be tested
The currently available speakers are displayed in a graphics box. Speakers that are not available are not displayed.
Click on the individual speaker to select or deselect it from the list of speakers to be tested. Click on A11 to select all speakers.
NOTE: If all speakers have been selected, clicking A11 deselects all speakers.
Speaker test sequence
To run an automatic test sequence
- Select the Auto button. This sends a two second test signal to each output channel in the sequence shown in the diagram at right. All other speakers are muted. The test sequence cycles through each speaker multiple times until the test signal is switched off.
- Click on Off in the Select Signal Type area to switch off the test signal and end the test sequence.

Output Trim
The Output Trim sliders control the audio signal level for each individual channel output. Only channels that are enabled in the current speaker configuration are available; the others are displayed but cannot be adjusted. Output trim is adjustable from -24 dB to +12 dB. The current value for each output channel is shown in the text box.
Figure 24. Output Trim
NOTE: The maximum output volume is tied to the output trim. When an output trim value is higher than 0 dB, the highest possible output volume is reduced by that amount. For example, if the highest output trim for any channel is set to +5 dB, the maximum output volume is -5 dB.
Extron recommends using a Sound Pressure Level (SPL) meter to set the output trim for each speaker:
- Set up the SPL meter at the sweet spot in the room.
- Send a test signal, generated as described in Test Signals on page 36, to each individual speaker in turn. Extron recommends using the Dolby Noise signal and sending the signals to the speakers manually.
NOTE: The test signal should have a sound level at least 20 - 30 dB above ambient levels.
- Measure and write down the sound pressure for each speaker.
- To avoid decreasing the maximum output volume (see the note above), Extron recommends that you use the speaker with the lowest SPL reading as the zero reference point. Then attenuate all the other speakers by the required amount to balance all speakers.
In the example below, the SPL readings for five channels are given in column 2. Channel 4 has the lowest reading and is used as the zero reference point. The difference between each speaker and the zero reference is calculated in column 3. This is the adjustment that must be made to the output trim for that channel.
| Channel SPL | Reading Output | Trim Adjustment (dB) |
| 1 75 -1 | ||
| 2 76 -2 | ||
| 3 79 -5 | ||
| 4 74 0 | (zero reference channel) | |
| 5 77 -3 |
- Use any of these methods to adjust the output trim for each speaker.
• Grab and drag the slider bar to adjust output trim in 1 dB increments.
- Click on one of the output trim slider controls to activate it and use the up and down arrows beside the text box to adjust it in 1 dB increments.
- Click on one of the output trim slider controls to activate it and use the up and down keys on the keyboard to adjust it in 1 dB increments.
- Click on one of the output trim slider controls to activate it and use the page up and page down keys on the keyboard to adjust it in 5 dB increments.
- Highlight the value in the text box, type a number (omit the dB), and press Enter on the keyboard.
The Reset button returns the output trim values for all speakers to the default value (0 dB).
Input and Output information bar
The Input and Output information bar is available from all GUI tabs and is described in detail on pages 28 and 29.
Speaker Equalization Tab
After the Testing & Output Trim tab, configure the Speaker Equalization tab.
Figure 25. Speaker Equalization Tab
The Speaker Equalization tab provides nine parametric EQs for each output channel. The default frequency values correspond to a nine-band graphic equalizer, which provides a starting point for refining the output signal from each speaker channel.
All the properties of the SSP 7.1 parametric EQs can be defined by the user.
Speaker selection
Select the speaker to be configured from the drop-down menu.
Figure 26. Speaker Selection Menu
EQ selection
Select the EQ to be adjusted (1-9) by pressing the desired numbered button and deactivating the corresponding Bypass button. The numbered buttons are a mutually exclusive set (only one button can be activated at a time). By default all EQs are bypassed.
Figure 27. EQ Band Selection Buttons
When an EQ has been selected, it can be adjusted in the graphic box or the text boxes at the bottom of the screen.
When the bypass is activated for an EQ, the values are saved for future use but do not act on the signal path. When the bypass is deactivated, changes made to that EQ contribute to the composite graph that is displayed. The graph shows how the activated EQs combine to affect the signal path in the current setup.
Right click the EQ number to bring up a context sensitive menu (see figure 27). Select Reset to return to default values for the currently selected EQ only, or select Reset A11 to return to default values for all EQs for the selected speaker channel.
Adjust EQ graphically
When an EQ is selected (see "EQ selection" on page 41) the EQ Graph displays a composite curve showing the individual EQ that is being configured with three parameter adjustment handles. A vertical white line marks the position of the handle (frequency) currently being adjusted.
Click and drag the EQ number (highlighted at the top of the graph) to adjust the horizontal position of the handle. Click and drag the center handle up or down to adjust the boost or cut level (in dB).
Click either of the outer handles to adjust the bandwidth, expressed as a Q value (frequency divided by bandwidth). If either of these outer handles moves, the other outer handle moves in the opposite direction to maintain a symmetry about the center handle.
NOTE: When values are altered in the graphics display, the numeric values in the "Adjust EQ Numerically" section (see next page) are updated to reflect the changes.
In the example below, the adjustment handles for EQ 3 are shown. The selected EQ is highlighted at the top of the graph.
line
| Frequency (Hz) | Value (dB) | | -------------- | ---------- | | 100 | -2.5 | | 200 | -2.0 | | 300 | -1.5 | | 400 | -2.8 | | 500 | -2.5 | | 600 | -2.5 | | 700 | -2.5 | | 800 | -2.5 | | 900 | -2.5 |Figure 28. Graph for EQ Band 3
In the graph below, EQs 1, 2, 3, and 4 have been adjusted. The effects of adjusting EQs 2, 3, and 4 can be seen by the deviation from the horizontal line. The effect of adjusting EQ 1 is not seen because the bypass button for that EQ is still activated and adjustments to EQ 1 are not used to process the audio signal. The numbers of the EQs contributing to the graph (2, 3, and 4, but not 1) are shown in white against a blue background at the top of the graph.

This sliding bar adjusts the Center Width control in the range 0-7. When the control is set to 0, the sound comes from the front center speaker. At 7, the sound comes from the front right and left speakers. The default setting is 3 (bold and underlined). See page 68 for more information about Center Width control.
DTS Neo:6 settings
Center Image Settings
These controls set the center image for DTS Neo:6 Cinema and DTS Neo:6 Music listening modes. More information about this listening mode is found on page 69.
The sliding bars adjust the center image control settings:
• DTS Neo:6 Cinema: 0 - 10 (the default is 10)
• DTS Neo:6 Music: 0 - 10 (the default is 3)
Setting the control to 0 creates the effect of spreading out the audio signal across the front speakers. Setting the control to 10 creates the effect of centralizing the audio signal.
See page 69 for more information about Center Image control.
Mono Settings
Two advanced configurations apply only to mono sources or outputs.
Analog Source (applies to Input 5 only)
A mono signal may be input as left channel only, right channel only, or the sum of left and right channels (both channels input identical mono signals). These controls allow the user to decide whether the Left Only, Right Only, or L+R (Sum) summed input becomes the source for the mono decoding mode. The default is L + R (Sum).
Output Channel(s)
These buttons let the user select whether mono signals are output to the center channel (Center Only) or a dual mono signal is sent to the right and left front channels (Front L+R Only). The default is Center Only.
Input and Output information bar
The Input and Output information bar is available from all GUI tabs and is described in detail on pages 28 and 29.
Drop-down Menus
The menu bar at the top of the window provides additional tools and options. The four top-level headings are File, Device, Options, and Help (see figure at right).
File
The File menu options allow you to save changes made to the configuration of the SSP 7.1, whether you are running the software in Live or Emulate mode. The current configuration can be saved as an *.esp file, which can be opened, further modified, saved, or saved by a different name. The File menu has five options.
New — If the software is in Emulate mode, you can save the configuration changes you have made to a new file by clicking on New. This creates a new file with the default settings that can be saved in any directory on your network.
Open — Opens an existing file. The current settings of the SSP 7.1 are replaced by the values in the file being opened.
Save — If the file that is currently being modified in Emulate mode has already been named and saved, this option saves any updates to the same file.

Reference Material
This section provides information about Source Formats and Listening Mode Options and Usage.
Source Formats
Surround Channel Information
Surround channel information is written in the following format:
A/B.C (For example 3/2.1)
A represents the number of front channels (maximum 3: front right, front left, and center). If A is 1, the source format has a mono encoded signal for playback through the center channel. If A is 2, the source format encodes two discrete channels for stereo playback through the front right and front left channels. If A is 3, there is a discrete encoded signal for all three front speakers.
B represents the number of surround channels (maximum 3: surround right, surround left, and back). If B is 1, the source format has a mono encoded signal for playback as dual mono through the surround right and surround left channels. If B is 2, the source format encodes two discrete channels for stereo playback through the surround right and surround left channels. If B is 3, there is a discrete encoded signal for all three speakers, including the back speaker.
NOTE: There is no "4" option because, while the SSP 7.1 can output up to eight full bandwidth channels, there are presently no source formats that can pass digital bit stream audio information containing 7.1 discrete encoded channels through S/PDIF connections, which is the connection type that the SSP 7.1 supports.
C represents the presence or absence of LFE (1 = present; 0 = none or absent). This is the discrete bass information, normally designated for use with the subwoofer channel, but may be mixed with other channels in the absence of a subwoofer.
| Encoded Channels Minimum RequiredOutput SpeakerConfiguration | |
| 1/0.0 or 2/0.0 2.0 | |
| 1/0.1 or 2/0.1 2.1 | |
| 2/1.0 5.0 | |
| 2/1.1 5.1 | |
| 2/2.0 5.0 | |
| 2/2.1 5.1 | |
| 2/3.0 6.0 | |
| 2/3.1 6.1 | |
| 3/0.0 3.0 | |
| 3/0.1 3.1 | |
| 3/1.0 5.0 | |
| 3/1.1 5.1 | |
| 3/2.0 5.0 | |
| 3/2.1 5.1 | |
| 3/3.0 6.0 | |
| 3/3.1 6.1 | |
NOTES: • The minimum allowable configuration of the SSP 7.1 is 2.0 because the left and right front speakers are always on. In the absence of a center channel, 1/0.0 and 1/0.1 encoded channels are output equally to both front channels.
- 7.0, 7.0 (with no center channel), 7.1, and 7.1 (with no center channel) are valid output speaker configurations. However, standard DVD audio sources cannot be encoded as 2/4.0, 2/4.1, 3/4.0, or 3/4.1.
- Blu-Ray DVD players output audio from Blu-Ray DVDs, which can carry 7.1 or more discrete encoded channels. However, that audio can be transmitted only via the HDMI output and can be processed only by an AV receiver that supports HDMI connections. The Blu-Ray player should support S/PDIF connections that output Dolby Digital and DTS multichannel source formats, which are also embedded in the Blu-Ray DVD and can be used to feed into the SSP 7.1 via a TOSLINK or coaxial connection.
Dolby Digital Source Formats (DD)
Inputs 1-4 only
Dolby Digital 5.1
(3/2.1, 3/2, 3/1.1, 3/1, 3/0, 3/0.1, 2/2.1, 2/2, 2/1.1, 2/1, 2/0.1, 2/0, 1/0.1, or 1/0)
Dolby Digital is a flexible, discrete, digital technology for carrying audio. Dolby Digital is a 5.1-channel surround sound format and is the standard for DVD video.
Dolby Digital features up to five discrete channels (front center, front left, front right, surround left, and surround right), which gives it the "5" designation. Each of the channels is full frequency with respect to human hearing (20 Hz to 20kHz). There is an additional channel reserved for low frequency effects (LFE), which is usually reserved for the subwoofer speaker(s) or other speakers capable of reproducing low frequencies (3 - 120 Hz). This gives the ".1" designation, since the sixth channel is not full frequency.
Although referred to as 5.1, it includes a variety of combinations, including 1.0, 2.0, 2.1, 3.0, 3.1, 4.0, 4.1, 5.0, and 5.1.
Dolby Digital 2/0
(2/0)
Dolby Digital 2/0 is a specific stereo format encoded by Dolby Digital technology. Encoded information is intended primarily for playback by the front left and front right speakers. TV broadcasts or DVD movie commentaries often have audio tracks encoded using this format.
When the SSP 7.1 detects this source format, both the ☐ and 2-CH LEDs are lit.
Dolby Digital 2/0 Surround
(2/0)
Dolby Digital 2/0 Surround is the consumer version of the original Dolby multichannel analog film sound format. Left, center, right, and mono surround are matrix-encoded onto two audio tracks. These two tracks can be decoded by Dolby Pro Logic to recreate the original four-channel sound. This source format is typically used for digital television broadcast signals and older, remastered, movies.
When the SSP 7.1 detects this source format, both the D and 2-CH LEDs are lit.
Dolby Digital Surround EX
(3/2.1)
Dolby Digital Surround EX is a commercial format that reproduces the center channel information through speakers placed directly behind the listener.
The back surround information is matrix-encoded onto the right and left surround channels of conventional Dolby 5.1 formats. If there is no back channel speaker, the information for that channel is played through the right and left surround speakers.
DTS Source Formats (DTS)
Inputs 1-4 only
DTS 2-Channel
(2/0)
DTS 2-Channel is a specific DTS encoded stereo format. Material encoded in this source format is typically found in DTS-HD Blue Ray DVDs and is primarily intended for playback by the left and right front speakers. When this source format is present, both the DTS and the 2-CH LEDs light.
DTS Digital Surround
(3/2.1, 3/2, 3/1.1, 3/1, 3/0, 3/0.1, 2/2.1, 2/2, 2/1.1, 2/1, 2/0.1, 2/0, 1/0.1, or 1/0)
DTS Digital Surround is a 5.1-channel surround sound format similar to Dolby Digital 5.1. As with the Dolby format, there are five full frequency channels (front center, front left, front right, surround left, and surround right) and an additional LFE channel.
DTS 96/24
(3/2.1, 3/2, 3/1.1, 3/1, 3/0, 3/0.1, 2/2.1, 2/2, 2/1.1, 2/1, 2/0.1, 2/0, 1/0.1 or 1/0)
DTS 96/24, provides high quality audio reproduction of music and movies from DVDs encoded with DTS Digital Surround source format information. The 96 kHz sampling frequency improves on the more typical 48 kHz. All DTS formats have 24 bit depth, which allows more audio information to be stored compared with the normal 16 bit depth.
DTS-ES Matrix 6.1
(3/2.1)
DTS-ES Matrix 6.1 is a 5.1 channel format with the back surround channel matrix-encoded into the right and left surround channels. This is achieved in much the same way as the front center channel is matrix-encoded into the front left and right channels of the Dolby Pro Logic format. The back surround channel is not discrete, so this is not a true 6.1 source format.
DTS 96/24 ES Matrix 6.1
(3/2.1)
This mode is similar to DTS-ES Matrix 6.1 but also has DTS 96/24 encoded.
DTS-ES Discrete 6.1
(3/3.1)
DTS-ES Discrete 6.1 has a back surround channel that is discretely encoded into the DTS bitstream. This format gives better sound spatialization for complete sound localization and sound pans (the movement of a sound source through the sound field). This format provides a data flag to signal the decoder that the bitstream contains an extra channel.
Material encoded in the DTS-ES Discrete 6.1 format cannot carry DTS 96/24 information because of bandwidth limitations as a result of the discretely encoded surround back channel information.
When the SSP 7.1 detects DTS source material with the DTS 96/24 feature, the sampling frequency of the signal is displayed by the SSP 7.1 Setup and Control Software. The SSP 7.1 Setup and Control Software also changes the text associated with the listening modes to reflect that DTS 96/24 is being output.
PCM Digital Source Format (PCM)
Inputs 1-4 only
Two channel, uncompressed, digital signals are processed through any of the four digital inputs. The sampling frequency of the digital signal is displayed by the SSP 7.1 Setup and Control Software.
When the SSP 7.1 detects this source format, both the PCM and 2 CH LEDs are lit.
2-Channel Source Format (2CH)
Analog
Input 5 only
Any balanced or unbalanced stereo signal (or two balanced or unbalanced mono sources) is accepted. This includes older VCR tape recordings that were labeled as having Dolby 2/0 Pro Logic audio.
Digital
Inputs 1-4 only
When the SSP 7.1 detects any two channel digital signal (including PCM, Dolby Digital 2/0, Dolby Digital 2/0 Surround, or DTS 2-Channel) the 2 CH LED is lit.
Sampling Frequency
The following table shows the most common sampling frequencies of digital inputs and the uses with which they are most often associated.
| Sampling Frequency (kHz) | Use |
| 32 Used | for some cassette recordings, speech, and all other audio where smaller files are desired, with only slight compromise on sound quality. In the past, used with products such as NICAMs. |
| 44.1 Audio | CD, also commonly used with MPEG-1 audio (VCD, SVCD, MP3). Adopted from the PCM adaptor using PAL video tapes (294 lines by 3 samples by 50 frames per second). |
| 48 Digital | sound used for mini DV, digital TV, DVD, DAT, films and professional audio. |
| 88.2 Sam | pling rates used by professional recording equipment when the destination is CD (multiple of 44.1k Hz). |
| 96 DVD | Audio, some LPCM DVD tracks, DTS 96/24, and DTS 96/24 ES Matrix 6.1 source formats always output this sampling frequency. |
Listening Mode Options and Usage
Listening Mode Options
Stereo
This mode plays a stereo source in its pure, unprocessed form. It is the default factory setting for any analog signal and any PCM or Dolby Digital 2/0 source coming through the digital inputs.
It can be used to downmix a multichannel source format into a mixed stereo output signal.
Mono
This mode plays mono source material or stereo that has been mixed to a mono form. It can be used to downmix a multichannel source format into a single mixed mono output signal.
The audio can be output to the center channel only or to the front left and front right channels as a dual mono signal.
Two advanced configurations apply only to mono sources and outputs.
Analog Source (applies to Input 5 only) — If two mono signals are input on input 5 (analog), the user can choose whether the source input for the mono decoding mode is Left Only, Right Only, or L+R (Sum). The default option is L+R (Sum).
Output Channels — This adjustment lets the user select whether mono signals are output to the center channel (Center Only) or a dual mono signal is sent to the right and left front channels (Front L+R Only). The default option is Front L+R Only.
Stereo to All
This mode plays stereo or downmixed stereo sources to all stereo channel output pairs in the system.
If the source is a single analog mono signal and the listening mode is set to Stereo to All, the following conditions apply:
- If the mono source is set to left channel only, the audio is output only to available left channels in the system.
- If the mono source is set to right channel only, the audio is output only to available right channels in the system.
- If the mono source is set to L+R (Sum), the audio is distributed evenly as a dual mono signal to all available stereo pairs.
Mono to All
This mode plays mono or downmixed mono sources to all channel outputs in the system. The mono source (Left Only, Right Only, or L+R (Sum)) can be selected using the SSP 7.1 Setup and Control Software or SIS commands.
Dolby Digital 5.1
This mode is used with Dolby Digital encoded source formats. It produces up to 5.1 discrete channels (center, left and right front, left and right surround, and a low frequency effects channel).
DTS
This mode is used with DTS Digital Surround encoded source formats. It also produces up to 5.1 discrete channels (center, left and right front, left and right surround, and a low frequency effects channel).
This is the default mode for DTS-ES Matrix 6.1 source formats when the system is set up for 3.0 to 5.1. It can be used with this source format to play the audio without the matrix-encoded back channel information.
DTS 96/24
This mode is used with DTS Digital Surround source formats that have been encoded using DTS 96/24. It also produces up to 5.1 output channels with audio sampled at 96 kHz at 24 bit depth.
This is also the default listening mode for DTS 96/24 ES Matrix 6.1 source formats for systems with a 3.0 to 5.1 speaker configuration or if the listener wants to play the audio without the matrix-encoded back channel information.
DTS-ES Matrix
This mode decodes DTS-ES Matrix 6.1 source formats, for use in a 6.0 to 7.1 system. Upon playback, the additional surround back channel signal is decoded from the surround left and right channels.
The listening mode can also be used with DTS Digital Surround sources where a surround back channel is created through matrix processing.
DTS 96/24 ES Matrix
This mode is similar to DTS 96/24 but is used with DTS-ES Matrix 6.1 source formats. It can also be used to extend DTS 96/24 source formats from 5.1 to 6.1 by creating a surround back channel using matrix processing.
DTS-ES Discrete
This mode decodes DTS-ES Discrete 6.1 source formats and reproduces all 6.1 channels, including the center channel information that was recorded independently, using the Digital Discrete system.
Dolby Digital EX
This listening mode decodes source material that was recorded using Dolby Digital Surround EX technology. It uses matrix mixing to produce extended surround back channel effects, which create 6.1 outputs from 5.1 source formats. When used with 6.1 source formats, the original back channel information is replaced by a matrix mixed sixth channel.
NOTE: This mode is available only when the SSP 7.1 is set up for 6.1 or 7.1 outputs and a multichannel Dolby Digital source format is available.
Dolby Pro Logic
This mode decodes source audio that is encoded in two-channel Dolby Surround to provide four-channel playback (center, left, right and mono surrounds). Sources include videocassettes, DVDs, and TV broadcasts.
Logic steering techniques extend the impact of the sound track over a wider listening area. This listening mode creates a mono surround channel with a high frequency roll off above 7 kHz.
Dolby Pro Logic II/IIx Movie or Music
Dolby Pro Logic II builds on Dolby Pro Logic by breaking the mono surround channel into a pair of stereo surround channels for playback in a 5.1 surround sound setup. This is achieved by a matrix surround decoder.
Dolby Pro Logic II works only with two-channel source formats that are used in a 5.1 configuration. It is available as Dolby Pro Logic II Movie and Dolby Pro Logic II Music.
Dolby Pro Logic II Movie is used for VCRs, TV broadcasts, and all programs encoded in Dolby Surround. Dolby Pro Logic II Music is used for any stereo music recordings.
Dolby Pro Logic IIx Movie and Music extend the Dolby Pro Logic II matrix decoding technology to derive up to seven channels from two-channel or multichannel sources, which provides additional outputs for surround back channel effects.
Both the Movie and Music modes produce up to seven full bandwidth matrixed channels. Music mode has hard back effects (shared across all surround speakers) instead of just the back speakers, which the Movie mode has.
Dolby Pro Logic II/IIx Music mode provides an additional set of commands to tailor the sound to individual listening tastes.
Dimension control
This alters the ratio of L+R to L-R for two-channel input signals. This has the effect of adjusting the sound field towards the front or towards the back, making the sound more or less spacious.
Center Width control
Pro Logic decoding produces a single center signal that comes from the center speaker. If there is no center speaker, a "phantom" center image is produced that is split between the right and left speakers. Center Width control allows variable adjustment of the center image so it is heard only from the center speaker, only from the right and left speakers, or from all three speakers in varying degrees.
Panorama control
This extends the Center Width control, so that all or part of the center image can be heard from the surround speakers for a “wraparound” effect.
Dolby Digital Pro Logic IIx Movie or Music
Both Dolby Digital Pro Logic IIx Movie mode and Dolby Digital Pro Logic IIx Music mode build on the Dolby Pro Logic IIx matrix mixing technology to create two additional surround back channels (right and left back) from the original Dolby Digital 5.1 channel information. The Dolby Digital Pro Logic IIx Movie mode (applied to multichannel sources) uses the same Dimension, Center Width, and Panorama controls that are available for Dolby Pro Logic IIx Music mode (applied to stereo sources). For more information, see the section above.
NOTES: • This listening mode is only available when the SSP 7.1 is set up for 6.0 to 7.1 channel outputs and a multichannel Dolby Digital source format is present.
- Dolby Pro Logic IIx Movie and Dolby Digital EX are electronically equivalent when the system is set up for 6.1.
DTS + Dolby Pro Logic IIx Movie or Music
This mode uses Dolby Pro Logic IIx matrix mixing effects to create up to two additional surround back channel effects from the original 5.1 information of a DTS Digital Surround source format. Both the Movie and Music modes produce up to seven full bandwidth matrixed channels for right and left back surround.
NOTE: This listening mode is available only when the SSP 7.1 is set up for 6.0 to 7.1 channel outputs and a DTS Digital Surround source format is present.
DTS 96/24 + Dolby Pro Logic IIx Movie or Music
This mode is similar to DTS + Dolby Pro Logic IIx Movie or Music (see above), but is intended for use with DTS 96/24 source formats.
DTS + Dolby EX
This mode uses Dolby Digital EX matrix mixing surround effects to create an additional surround center back channel from the discrete 5.1 information of a DTS Digital Surround source format to create up to 6.1 channel effects.
NOTE: This listening mode is available only when the SSP 7.1 is set up for 6.1 to 7.1 channel outputs and a DTS Digital Surround source format is present.
DTS 96/24 + Dolby EX
This mode is similar to DTS + Dolby EX (see above), but is intended for use with DTS 96/24 source formats.
DTS Neo:6 Cinema or Music
This mode produces up to seven separate full bandwidth matrix channels from a 2-channel (stereo) audio input.
DTS Neo:6 Cinema assigns the in-phase component of the signal to the center channels and the reversed-phase component to the left and right surround and center back or left and right back channels.
With DTS Neo:6, the left and right front channels bypass the decoder and are played directly with no loss of sound quality. The signal outputs from the center, right surround, left surround (for 5.1), the center back (for 6.1), or left and right back (for 7.1) channels. In the DTS Neo:6 Music or Cinema mode, there is one adjustable control:
Center Image control
The Center Image control varies the amount of attenuation applied to the left and right channel information of the input source that is used for creating the output center channel effects. When it is set to 0, the mixed input signal information, intended for use in creating the center output channel of the DTS Neo:6 listening modes, is filtered back to the front left and right output channels. This creates the effect of spreading the centralized audio signal across all three front output channels. When this control is set to 10, the matrixed information intended for the front left and front right output channel effects is fully attenuated, allowing the center channel to create a more centralized effect from the front channels.

SIS Commands
This section provides information about the Extron Simple Instruction Set (SIS ^™ ) commands that are used to configure the SSP 7.1 in the following sections:
• Introduction to SIS
• Symbols Used in this Manual
- Error Messages
• Expected Unsolicited Responses
• Command and Response Table for SIS Commands
- Setting Speaker Delay Settings using SIS Commands
- Setting up Test Sources with SIS Commands
Introduction to SIS
The SSP 7.1 accepts SIS commands from a host device such as a computer running the HyperTerminal utility or other control system. The host device can be connected to the 3-pin captive screw connector on the rear panel or to the config port on the front panel. To connect to the config port, use the optional Extron 9-pin D female to 2.5 mm TRS Configuration cable (part number 70-335-01).
The protocol is 38400 baud, 8 data bit, 1 stop bit, and no parity.
NOTES: • The wiring in the RS-232 cables crosses over so that the surround sound processor Tx connects with the control device Rx and vice versa.
- Both the rear panel RS-232 port and the front panel configuration port can be used at the same time. Neither has precedence. The SSP 7.1 responds to commands in the order received.
SIS commands consist of a string (one or more characters per command field). Unless otherwise stated, upper and lower case characters may be used interchangeably. Commands do not require any special characters to begin or end the command string. Each response from the SSP 7.1 ends with a carriage return and a line feed (CR/LF = ←), which signals the end of the response character string.
When the SSP 7.1 is first switched on, depending on the model, it sends the message:
(c) Copyright 2010, Extron Electronics, SSP 7.1, 60-842-01, V x.xx← where 60-842-01 is the catalog part number and V x.xx is the firmware version number.
Symbols Used in this Manual
When programming in the field, certain characters are most conveniently represented by their hexadecimal rather than their ASCII values. The table below shows the hexadecimal equivalent of each ASCII character:

Setting Speaker Delay Settings Using SIS Commands
NOTE: It is strongly recommended that, for ease and simplicity, these adjustments are made with the SSP 7.1 Setup and Control Software (see page 22). If this is not possible, the delay values can be calculated and entered, using SIS commands.
To adjust Compensation Delays using SIS commands, follow these instructions.
Two Person Setup
NOTE: Setting up speaker delays is easier with two people. If only one person is available, the position of the listener's ears must be marked precisely using, for example, a pile of boxes. Do not try to guess ear positions, as this introduces measurement errors.
- Pick an ideal central location where all speaker output signals converge.
- Use a tape measure to measure the distance from each speaker to the convergence location. Be sure to measure to the same spot from each speaker.
NOTE: Measurements from the speaker should be to the midrange driver in a three-way speaker or from halfway between the tweeter and the woofer in a two-way speaker. Measurements to the convergence location should be at ear height.
- When the distances to every speaker have been measured accurately, select the speaker that is farthest from the convergence location and use that distance as a reference value.
-
Calculate the delay distance for each speaker, where: Delay Distance = Farthest Speaker Distance - Individual Speaker Distance
-
Calculate the delay time (in ms) for each speaker, where:
Delay Time = Delay Distance / Vs
NOTE: The constant Vs (the speed of sound) is 0.343 m/ms or 1.12533 ft/ms.
- For SIS commands, the delay time must be converted to units of 0.1 ms:
SIS Delay time = Delay Time (per ms) x 10
- Compile the information into a table (if possible, use a spreadsheet program to carry out the calculations automatically). An example, using typical values, is given below:
| Speaker Channel | Measured Distance (ft) | Delay (ft) Delay Time (ms) | SIS Delay Time |
| Left 12.00 (furthest speaker) | 0.00 0.0 0 | ||
| Right 11.00 1.00 | 0.9 9 | ||
| Center 10.50 1.50 | 1.3 13 | ||
| Left Surround 8.25 | 3.75 3.3 33 | ||
| Right Surround | 7.50 4.50 4.0 40 | ||
| Left Back | 6.13 5.87 5.2 52 | ||
| Right Back | 7.50 4.50 4.0 40 |
Table 4. Calculating Speaker Delays for SIS commands
- Use these SIS Delay Time values when entering SIS commands to compensate for speaker delay where there are no Lip Sync effects (see Speaker Delay Settings).
Setup with a RTA Calibration Tool
- Pick an ideal central location on which all speaker output signals converge.
- Place the microphone from the RTA at ear level in the convergence location.
- Play the audio source. This can be an analog source, provided by the RTA, or a digital source, provided by a test CD.
- Use SIS commands to change the listening mode for the input signal to "Mono to All." If necessary, configure the mono source to Left, Right, or, if using an analog input, Left + Right.
- Use SIS commands to mute or unmute specific output channels.
- Use the RTA to measure the outputs of each channel.
- Calculate the speaker with the longest delay (normally recorded in ms)
- Calculate the Delay Time (in ms) and the SIS Delay Time for each speaker and compile the values in a table as described in the "Two Person Setup" section.
NOTE: The RTA provides Delay Times in ms, so there are no columns for Measured Distance (ft) or Delay (ft).
- Use these SIS Delay time values when entering SIS commands, to compensate for speaker delay where there are no Lip Sync effects (see Speaker Delay Settings).
Setting up Test Sources with SIS Commands
Extron recommends that the SSP 7.1 Setup and Control Software is used to calibrate the system with the test signals, as described on page 36. If this is not possible, the system can be calibrated using SIS commands.
Using Pink Noise or Dolby Noise test signals
- Send the SIS command that turns on the test source as Pink Noise (EscX2TSTA←) or Dolby Noise (EscX1TSTA←).
- Send the SIS command that mutes all output channels (1Z).
- Send the SIS command to unmute each output channel individually ( 2* Z where 2 represents the number of the output channel).
- The signal is output through the unmuted channel; the user can adjust speaker delay or output trim and hear the test noise change in real time.
- Mute the current output and unmute the next channel to test each output in turn.
- To end the session send the SIS command that turns off the test source (Esc)X0TSTA← and the SIS command that unmutes all channels (∅Z).
Using External Source test signals
- Select the input that provides the test signal.
-
Change the listening mode for the source format of the input signal to "Mono to All," using SIS commands in one of the following ways:
a. Configure the user mode settings to auto select "Mono to All" as the format of the input signal. If the listening mode was changed, the source is downmixed to mono, which is output to all available channels at equal levels.
OR
b. With a source actively playing, toggle through the mode override options to select "To All." Enter the SIS command EU 1 *4*8SSP← to change the option to "Mono to All." 1 is the input channel, 4 is for the "To All" Mode Override Group, and 8 selects "Mono to All." -
Play the source audio through the selected input.
- If the user mode was correctly set to "Mono to All" in step 2, the output should be heard equally from all channels. If not, toggle the Mode Override button on the front panel to "To All" to enable "Mono to All."
- Send the SIS command that mutes all output channels (1Z).
- Send the SIS command to unmute each output channel individually (x2*∅Z where x2 represents the number of the output channel).
- The signal is output through the unmuted channel; the user can adjust speaker delay or output trim and hear the test noise change in real time.
- Mute the current output and unmute the next channel to test each output in turn.
- To end the session, send the SIS command that turns off the test source (Esc)X∅TSTA← and the SIS command that unmutes all channels (∅Z).

Rack Mounting
UL Guidelines for Rack Mounting
The following Underwriters Laboratories (UL) guidelines are relevant to the safe installation of these products in a rack:
-
Elevated operating ambient temperature — If the unit is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the equipment in an environment compatible with the maximum ambient temperature (Tma: +122 °F, +50 °C) specified by Extron.
-
Reduced air flow — Install the equipment in the rack so that the equipment gets adequate air flow for safe operation.
-
Mechanical loading — Mount the equipment in the rack so that uneven mechanical loading does not create a hazardous condition.
-
Circuit overloading — Connect the equipment to the supply circuit and consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Appropriate consideration of the equipment nameplate ratings should be used when addressing this concern.
-
Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips).
Rack Mounting Procedure
The unit can be mounted on any of these optional rack systems, including:
• RSU 129: 9.5 inches deep, 1U rack shelf kit (part number 60-190-01)
• RSU 126: 6 inches deep, 1U rack shelf kit (part number 60-190-10)
To mount the scaler on a rack shelf, follow the instructions provided with the shelf accessories.
Under-desk Mounting
Mount the unit under a desk or podium, using the optional Extron MBU 125 under-desk mounting kit (part number 70-077-01) by following the instructions provided with the MBU 125 kit.
Glossary
Bass Management — Low frequency sounds are usually better handled by the subwoofer speaker. Bass Management organizes the low frequency component of designated input signals, along with the Low Frequency Effects (LFE) information encoded in the source format and passes that information to a subwoofer (if available). (Also see Crossover Frequency, Low Frequency Effects, and Speaker Size.)
Center Image Control — (DTS Neo:6 Music or Cinema) This control attenuates the level of the front left and right speakers without affecting the level of the center channel to create a better balance. There are eleven possible settings, from 0 to 10. At setting 0, there is no attenuation of the right and left front channels, so that the center channel spreads out. At setting 10, there is maximum attenuation (6 dB) of the right and left front channels, which allows the center channel to dominate. The default setting for DTS Neo:6 Music is 3; the default setting for DTS Neo:6 Cinema is 10.
Center Width Control — Pro Logic decoding produces a single center signal that comes from the center speaker. If there is no center speaker, a “phantom” center image is produced that is split between the right and left speakers. If right, left, and center speakers are present, center width control allows variable adjustment of the center image so that it is heard only from the center speaker, only from the right and left speakers, or from all three speakers in varying degrees.
Compensation Delay — In a room where speakers are not equidistant from the listener, sound from the closest speaker reaches the listener before sound from the farthest speaker. This adjustment delays the signals going to individual speakers: the signal to the speaker farthest from the listener is not delayed while speakers that are closer to listener, are. This ensures that the sound from each speaker reaches the listener at the same time.
Crossover Frequency — The crossover frequency sets the boundary below which the low frequency signals from designated output channels are incorporated into Bass Management. The Bass Management signal is passed to the subwoofer (if present) and speakers that have been set to output the signal. (Also see Bass Management, Low Frequency Effects, and Speaker Size.)
Dimension Control — This feature alters the ratio of L+R to L-R for two-channel input signals, which adjusts the sound field towards the front or towards the back. The available settings are Front, Neutral, or Back. The default setting is Neutral.
Dolby Noise — Dolby noise provides a bandpass-filtered noise, centered at 750 Hz with a 12 dB/octave roll off. This signal is also generated by the SSP 7.1 and is used to set speakers to the same level when calibrating the room.
Downmix — multiple channel signals are mixed to produce a stereo or mono output signal.
Dynamic Range Compression — This control adjusts the gain applied to Dolby Digital or DTS listening modes to compress the signal outputs during the decoding process. The three possible settings are None, Minimum, and Maximum. The default setting is None.
Equalization — The level of different frequency bands can be adjusted to enhance tone, compensate for differences in individual speaker output and to remove extraneous noise, feedback, and resonance.
Executive Mode — see Front Panel Security Lockout.
External Source (Test Signal) — An external calibration source, is usually used to test specific decoding mode outputs. When the External Source option is chosen, the speakers that receive the test signal can be specified.
Front Panel Security Lockout — When Front Panel Security Lockout is enabled, the front panel is locked and the user is unable to make any changes from the front panel (except disabling the lockout). It does not block changes made using SIS commands or the SSP 7.1 Setup and Control Software.
Listening Mode — The listening mode determines how the signals of the source format are decoded and distributed to the system's speakers. Not all listening modes are available for every input mode and the SSP 7.1 offers factory defined listening modes that are matched to the source format and speaker configuration. The user can override the default listening mode to fully define a listening mode that suits the source format, the speaker configuration, the room in which the system is installed, and the listener's personal preferences.
Low Frequency Effects (LFE) — This information is encoded in the source signal and is intended to be played back by the subwoofer. Bass management mixes this information with the low frequency signals from designated output channels and directs it to the subwoofer (if present) and speakers that have been set to output the signal. (Also see Bass Management, Crossover Frequency, and Speaker Size.)
Mode Override — The user can customize the listening mode to the needs of the source format, speaker configuration, and the venue in which the system is installed through the use of the Listening Mode Override. This is a front panel control that can be further refined by the SSP 7.1 Setup and Control Software.
Mute — It is possible to completely silence the output from all channels (universal mute) or each channel individually.
Panorama Control — This feature extends the Center Width Control, so that all or part of the center image can be heard from the surround speakers for a "wraparound" effect. The feature may be On or Off. The default setting is Off.
Pink Noise — Pink noise is a random signal with all audio frequencies present, that is generated by the SSP 7.1. It provides equal energy per octave to provide a flat response over all frequencies. The main purpose of pink noise is to calibrate a speaker's interaction with its environment.
Test Signal — Test signals are used during setup to calibrate each channel's levels and to ensure proper connection between the SSP 7.1's individual output channels and the line level input channels of an audio signal processor, a receiver with built in amplifier, or a stand alone amplifier that powers the loudspeakers. There are three options for test source: Pink Noise, Dolby Noise, and External Source.
Simple Instruction Set (SIS) — The SSP 7.1 accepts SIS commands from a host device such as a computer running the HyperTerminal utility or other control system. SIS commands consist of a string (one or more characters per command field). The commands are used to configure the SSP 7.1 unit and, depending on the command, usually produce a response which can be seen on the screen of the host device.
Source Format — Audio signals are recorded and processed in different formats. The recorded signals contain differing amounts of information, encoded in different ways, and the format determines how accurately the sound that is played back reflects the original sound as it was recorded.
Speaker Size — Speakers can be set to Large, Small, or None. Speakers set to Large play the full range of sound intended for that output channel. Speakers set to Small play only the frequencies that are above the crossover frequency. The low frequency portion of the signal from that channel is incorporated into bass management and directed to the subwoofer (if present) and speakers that have been set to large. Speakers that are set to None, are effectively removed from the system and do not receive an output signal. (Also see Bass Management, Crossover Frequency, and Low Frequency Effects.)
Tone Controls — These controls regulate the bass and treble settings for the system, using the SSP 7.1 Setup and Control Software or SIS commands.
