Equipment Type A: Equipment that is intended for connection to the building power supply wiring via non-industrial plugs and sockets or via appliance couplers or both.

2.1 System Hardware Mounting and Grounding

The JSD-80 is designed to mount in a standard 19" rack, and is two standard rack spaces (3-1/2") high. We recommend vent panels above and below whenever space permits. Mounting the unit immediately above a major heat-producing component (such as a power amplifier) is not recom-

mended. The JSD-80 includes a three-prong grounding plug and a three-wire power cord to accommodate a safe ground path from the chassis to the electrical system ground. Defeating this ground by removing the ground prong is not recommended.

2.2 System Cooling and Ventilation

Important

Care should be taken to insure the JSD-80 has adequate ventilation for cooling during operation. It is recommended that one rac space below the JSD-80 is left open to allow outside air circulation through the unit. A ventilation panel, USL, Inc. part number VP-1, is recommended for projection boot where the normal ambient temperature

exceeds specified equipment operating temperatures listed in the safety section of this manual. Also, it is recommended that equipment with no more than a nine-inch depth be mounted directly above the JSD-80 to insure adequate airflow through the unit's rear ventilation slots.

5.1 Overview

The front panel allows the operator to manual select formats and adjust the main fader. An L numerical readout indicates fader level. Status LEDs indicate presence of power supplies. The unit is placed into the bypass mode by turning off the main power switch. A removable panel allows access to service or replace modules.

5.2 Adjusting Format Levels

Each format has a preset level. These presets can be set with a laptop or directly on the front panel. Pressing and holding the appropriate format button and rotating the main fader will change the preset level for that format. The LF display will indicate the preset level number

5.3 Adjusting Projector Gains

1. Turn off the processor.
2. Hold down the "Mute" button and turn the power on.
3. Continue to hold the "Mute" button until the LED display indicates 1.1 which means Projector 1, Left channel.
4. Run a Cat 69T tone loop on the projector.
5. Watch the LED level indication on the Input Module: (9 & 10).

1. If the left indicator (9) is red, the signal is too low. Rotate the main fader control clockwise to raise the level. When the level is correct, the indicator (9) will turn green. A flashing red means that the signal is too high.

2. When the left indicator is green, press the "Mute" button to signal OK. The display will change to 1.2 (Projector 1, Right Channel). Adjust the main fader until the right (10) indicator turns green. Press "Mute." The optimum setting is first click from solid red to solid green.

3. The LED display will show 2.1 (Projector 2, Left Channel). Press “Mute” when adjustment is complete. If there is no Projector 2, press “Mute” twice to return to normal operation. If there is a Projector 2, press “Mute” once and proceed to step 9.

4. The LED display will show 2.2 (Projector 2, Right Channel). Press "Mute" when the adjustment is finished

5. The last "Mute" button press will return the system to its normal operating mode. Operation will resume after six seconds.

6.2 Back Panel Input Connections

Projector Inputs

The projector inputs are connected through standard 9-pin D-type connectors. (These connectors are included with the JSD-80).

The pinout is:

1. In L+
2. In L-
3. Shield
4. In R+
5. In R-
6. Gnd
7. Reserved
8. Reserved
9. Gnd

(An adapter board with setscrew terminals is available for solderless connections.)

Non-Sync Inputs - Analog

Two RCA connectors facilitate easy connection to standard CD players. A software fade in/fade out algorithm allows smooth transition between intermission music and the main program.

Auxiliary Input - Analog

Two RCA connectors are used to connect to external two-channel sources such as a sound card in a computer supplying video advertising content.

Microphone Input

The public address balanced microphone input is available on a standard 9-pin D-typ connector.

The pinout is:

1. Mic in +
2. Mic in -
3. Reserved
4. Reserved
5. Chassis Gnd.
6. N/C
7. 9 V DC
8. Gnd
9. N/C

The “Mic in +” and “Mic in -” terminals are for the balanced medium-low impedance

microphone inputs. The shield of the microphone cable should be connected to chassis ground on pin 5. A 9 V DC power pin allows easy connection of electret (powered) microphones.

EXT 1 (Analog)

The Analog input is an eight-channel un balanced analog audio input from a digital soundtrack player. The 25-pin D connector is compatible with most decoders. Input level should be 300 mV for all channels. Se Section 12.

EXT 2 (Digital)

The Digital input is a digital domain input configured for eight channels (Four AES-EBU pairs with sample rate from 32 to 96 kHz). Requires optional AES-EBU Module (DI85). See Section 12

Non/Sync Inputs - Digital

Requires optional Module (D183). An RCA jack accepts S/PDIF inputs from CD, DVD, or computer sound cards. Sample rates from 32-96 kHz PCM are supported, AC3 bitstreams are also supported.

The DI83 module in this processor, which decodes Dolby® Digital bitstreams, is not intended for 35mm fi lm. The DI83 is intended for alternative content only.

Auxiliary Inputs - Digital

Requires optional Module (DI83). An RCA jack accepts S/PDIF inputs from CD, DVD, or computer sound cards. Sample rates from 32-96 kHz PCM are supported. AC3 bitstreams also are supported.

6.3 Back Panel Signal Output Connections

Main Outputs

These are the main processor outputs to connect to the power amplifiers. The outputs are balanced, and all have a corresponding ground terminal. Use two-conductor shielded cable for each channel. The shield should usually be connected to ground at the power amplifier end only

Monitor Outputs

This is a 25-pin D-type connector containing the line output signals for all eight channels. It can be connected directly to any Ultra Stereo "CM" series monitors. The pinout for this connector is in Section 12.

Hearing Impaired Output

This line-level output is the sum of the left, center, and right channels. It can be connected to an “Ultra Phonic” or other hearing impaired system. Output level is approximately 300 mV

Back Panel Automation Connections

Automation Inputs (Phoenix Connector)

These are active low-contact closure input to remotely trigger the JSD-80. There are nine automation inputs; one for each of the eight JSD-80 operating formats, and a "Mute" input. These are intended to be momentar contact closures. The "Mute" function is released by selecting (or re-selecting) one of the main input formats.

The Automation common terminal is isolated from the system ground through an internal 10 Ohm resistor to minimize group loop problems.

Note: When wiring the automation in puts, use the Com terminal, not a ground terminal.

Automation (DB-25)

This 25-pin D-type connector contains most (not all!) of the automation input and output signals. The pinout for this connector is in Section 12.

Note: An adapter is available to convert to the DTS automation pinout (DTS-6D).

LEDs for monitoring the status of the JSD-8 can be connected in series with a 1k resist from +5 V at pin 13, to any of these outputs. See Section 12.

Bypass Power Input

The JSD-80 uses an external 16 V AC @ 500 mA power supply to power the bypass circuit.

Remote Fader Input

Two normally open switches can be used to implement a remote fader. One button increases level, the other decreases level. The range is limited to 4.0 - 9.0 on the main fader. See Section 10.3

Changeover

The JSD-80 includes dual preamplifiers for use in two-projector changeover systems. Connecting the "XO" terminal to "Common mutes the Projector 1 input and selects Projector 2. This must be a maintained closure.

RS232 Port

A standard 9-pin D-type connector connect to a host PC computer. The cable should be a standard male to female “straight through” type. The port also can be used for remote fader and automation functions See Section 12.

7.1 Installation Procedure

Begin by placing the JSD-80 Laptop Interface Software CD into your CD-ROM drive. The software is compatible with Windows only. The installation program should start automatically within a few seconds. If it does not, you will need to run "Setup.exe" from the root directory of your CD-ROM drive. Either double click the "Setup.exe" icon or click the Windows "Start" button and select "Run..." Now enter "X:\setup.exe" (where "X:" is your CD-ROM drive), then click the "OK" button. Follow the instructions in the installation software.

7.2 The Opening Screen

Double click on the JSD icon on the desktop.

The opening screen appears.

The opening screen is comprised of the Menu Bar, the Tool Bar, tabs for accessing software functions and, on the Profi le tab, a system information entry area.

At the top of the opening screen is the Menu Bar. The menu bar gives access to various functions. These functions are duplicated on the Toolbar (with the exception of "Language"), and through keyboard key combinations.

The toolbar consists of graphic icons allowing you access to various functions. Holding the mouse pointer over any of the icons will give you a "tool tip" describing function of the icon. The horizontal slider at the far right is the main level control (or Main Fader). The level may be changed from the main screen by placing the cursor ove:

the slider, holding down the left button an moving the mouse.

Below the toolbar are tabs for accessing various operational modes. These tabs will be described in order from left to right.

7.3 Profi le Screen

On the first tab, there are several windows for entering information about your system and peripheral equipment. This information is stored in the .JSD-80 and also can be stored on the computer or the device used to set up the unit. This information is not used by the unit functions but can be extremely valuable to technicians for the purposes of repair and re-alignment or in case of the necessity of a factory repair. You can enter this information at any time whether connected to the .JSD or not and save it to disk for eventual loading onto the .JSD. The "Component Information" boxes are filled in at the factory and are not editable by the end user. At the bottom right of the tab are the connection status bar and the format status bar. No matter which tab you are working in, the format status bar will always indicate in which format the processor is currently operating

Note: When the computer is connected to and controlling the JSD-80, the front panel controls will no function, with the exception of the Mute button.

7.4 Formats Screen.

This is where you set the processor's mod of operation. Anyone familiar with the operation of a motion picture venue should also be familiar with the above formats. Any of the formats may be designated the "Power On" format which means that when the power is turned on, the processor will "wake up" in that mode. The Non/Sync and Aux inputs have the option of being either an analog or S/PDIF input. The Mic input can be routed to either the center or the surround channels. The fader at the left of the window allows you to pre-set the level of a particular mode. The master level will follow that setting. When you go to another mode and set its level to whatever you desire, upon your return to the original mode, the level will be the same as you left it. Along with the standard "Power On" choices, which are visible in all format selections, a "Digital Fallback" selection appears whenever you select Ext 2 (Digital). This allows you to select a mode to automatically default to, should the digital track become interrupted for any reason. A Digital Delay button (which brings up a separate screen on which you can set input and surround delay) also becomes visible in Ext 2 mode well as when S/PDIF is selected in either the Non/Sync or Aux formats. See Section 8.8.

7.5 Inputs Screen.

There are two sections.

The first section is the Preamp Controls station and contains buttons to select either Projector 1 or 2 level settings for the Left and Right preamps (with accompanying level indicators), Slit EQ & Mono EQ and the Slit EQ Analyzer screen which is dealt with in detail in Section 7.8. This tab is where the alignment is accomplished for the optical preamp (A Chain), and is vital for accurate optical performance.

The second section is a matrix controls section for setting the delay & gain of the surround channel, and the gain & frequency of the subwoofer. The level functions are accessed by placing the pointer over the desired slider's button, holding down the left mouse button and moving the mouse. Note that when a slider is selected, it is highlighted and will stay that way until another slider is selected. The sliders (once they are selected) also may be manipulated by using the up or down arrow keys; the left/right arrow keys will select the sliders on the left or right of the one initially chosen. At the bottom of the slider is a box that states numerically the position in dB of the slider

7.6 Equalizer Screen.

This is used for all equalization of the auditorium. With the radio buttons, you may select the channel to be equalized. The channels consist of Left, Center, Right, Left Surround, Right Surround, Subwoofer and two additional channels. (Note: When you select Subwoofer, a separate screen appears containing a Sub Bass Parametric EQ.)

The sliders also will respond to the push c

an "up" or "down" arrow key and, for every push, the level will change .1 dB. Clicking on the button labeled "Flat" will restore all slider settings to the mid point and will wait you (if you accidentally hit it) before acting on the command.

Note: If a channel should appear highlighted in red, it indicates that the channel has been muted on the Outputs Screen (see Section 7.7).

7.7 Outputs Screen.

This is where, during the alignment process the output levels are set for the various channels. A signal generator is available which can be set to four different modes. To select the particular generator function choose the function with the radio buttons on the bottom of the screen. To assign a particular channel to receive generator output, a box is available below the slider. These boxes may also be utilized to Mute or Invert the channel. The faders change in 0.5 dB increments

Note: When using the generator, the default mode allows one active channel at a time. Holding down the key allows selection of multiple channels for the generator (e.g., center and subwoofo channels).

7.8 Slit EQ Analyzer Screen

To the right of the Preamp Level Faders is screen with annotations on the bottom and left side and buttons at the top. This is the Real Time Analyzer built into the JSD-80. You must be connected to the JSD-80 and it must have a signal source before it can become functionally effective. Move the mouse arrow over one of the buttons and a pointer appears. Click the "Power" button and a line appears across the screen. You can utilize the Real Time Analyzer in the following ways: utilizing the third button from the top left, you can select either Normal or Sum & Diff. In the "Normal" mode, you have the option of selecting (with the second to button), either Left, Right, or Left + Right. The Sum & Diff mode, you can select (with the second top button), either Sum, Diff or Sum + Diff. You can view the performance the left channel and right channel, Sum or Diff as either bars or lines. On the left hand side of the screen are gradations measured in decibels. As you can see, they often extend below the level of the screen. Moving the mouse pointer over these gradations and holding down button one, a pointer appears once again, with an accompanying arrow. You can move the numbers and the screen up to view the signal, down to a level of -50 dB and up to +20 dB if so desire Double click on the screen and it expands a larger representation that can be seen at greater distance. The larger screen can be maneuvered on the computer's screen access controls.

7.9 Creating, Saving and Loading Configuration Files

Use the "New" command to create a custom configuration file starting with factory defaults.

Use the “Save” or “Save As” command to save your custom configuration file to the hard disk.

You may load a previously saved file by using the "File," "Open" command and selecting the desired configuration file. If you are connected to the unit, the parameters will be automatically uploaded.

(See also: System Restore From Personality Module, Section 10.4.)

Please take the time to familiarize yourself with the laptop interface controls and screens. Next establish communication with the JSD-80 using a standard RS232 cable. Select the "Connect" icon on the toolbar and everything is as it should be, the computer will connect with the JSD-80.

When you first accessed the JSD software, the small window in the lower right hand corner of the main window looked like this:

Disconnected

Once you connect to the JSD, the compute will download all the data stored on the JSD-80 to the laptop's memory. This data can consist of Preamp Parameters, EQ Parameters, Front Panel Parameters and Profi le Information. Once that action has taken place, the small window will change to this:

Connected

You are now ready to set up the JSD-80 If you are setting up the JSD-80 for the first time, you may want to fill in the particular of the venue in the “Theatre Information” boxes provided in the Profile tab. They

may be filled in and edited like a normal text file

The “Component Information” boxes are filled in at the factory and are not editable by the end user.

Note: As stated previously, this information is not functional insofar as the operation of the processor is concerned but can aid you greatly in future endeavors.

At any time during the Profile entry or setup procedures, the information from those tasks may be saved to the laptop's hard drive or other convenient data storage medium by utilizing the "Save" function an providing a path and file name

After completion of the alignment procedure (see Section 8), the complete system configuration may be saved to the laptop's hard drive or other data storage medium by utilizing the "Save" function and providing a path and file name

Section 8. "A" Chain Alignment

8.1 Preparing The Sound Head

1. Clean the soundhead optics thoroughly. If the film guide rollers are worn, replace them. Excessive side to side weave will cause insurmountable problems for the stereo circuitry and must be corrected prior to installation.
2. If the exciter lamp is old or blackened inside, replace it. Make sure the lamp operating at a voltage greater than 60 of its rating. We strongly recommend converting the projector to be compatible with the new cyan soundtracks with a red LED lamp source such as an ULTRA*STEREO Jaxlight or RSTR Reverse Scan Reader.
3. With the mono solar cell in the projector, run the SMPTE BUZZ TRACK fi lm and align the guide rollers for minimum output.
4. For stereo installations, remove the mono solar cell and place a white car about an inch away from the sound lens. The image of the exciter lamp fi lament should look as in the illustration below. If necessary, raise or lower the lamp and move it in and out until the fi lament is centered in the spot of light. This will insure that the slit is evenly illuminated, thereby producing the least distortion in playback.

8.2 Alignment of Solar Cell and Preamplifi e

1. Mount the stereo solar cell on the projector and position the bracket, so that the slit image hits the upper part of the cell. The cell should be approximately 0.040 inch (1 mm) behind the film such that the slit image just fills the cell width, but does NOT spill over

1. Install the audio line from the cell to the JSD-80. Use Belden N° 8404 or equivalent four-conductor twin-shielded cable, or a pair of two-conductor shielded cables such as Belden N° 8451. (A single two-conductor or three-conductor shielded cable is not recommended.) Connect the lines to a 9-pin male D-type connector. The pinout for this connector is in Section 12. Be sure that the RED lead of the cell is connected to the "L" input terminal marked "+" and the GREEN lead of the cell is connected to the "R" input terminal marked "+" . The BLACK cell leads connect to the low "-" input terminals of BOTH Left and Right channels respectively.

Connect the shielding of the cable to the Chassis terminal (pin 3). Do not connect the shielding at the projector end. The D-9 connector should be plugged into the Projector 1 input of the JSD-80.

1. Film readers with active circuits, such as a Jaxlight line amplifier or a reverse scan reader, will require a ground connection at the reader. Good results can be achieved using the drain (shield) wire of the cables listed above, however, some agencies (such as CE) prohibit using the drain conductor for this purpose. In that case, use two 3-conductor shielded cables (such as Belden N° 9939) (see Section 6.1).
2. If there are two projectors, the change over is accomplished by grounding the "X-OVER" terminal. Connect a latching relay, with the appropriate rating, so that one coil is powered by the dowser circuit of Projector 1 and the other coil is powered by the dowser circuit of Projector 2. The relay contacts must be connected to the "XO" and "COM" terminals so that the contacts are closed when Projector 2 is operational.
3. Set the JSD-80 preamp controls so the gain is at the midpoint and the high frequency boost fi liters are at the maximum frequency (32 kHz). This can be accomplished from the JSD Laptop Interface Software. Connect a dual trace oscilloscope to the test points on the JSD-80 "Input Module" board. "Left" is RED, "Right" is GREEN, and "GND" (Audio ground) is BLACK. Run a 100% alternating left/right STEREO ALIGNMENT fi lm and move the cell in and out until the crosstalk is at a minimum on both channels as shown. It may be necessary to set the gain of the preamp roughly at this time.

Two overlapping wavy line patterns, no text or symbols present

1. Run a 50% level film such as the Cat 69T or equivalent. Adjust the Left and Right level controls on Projector 1 until the preamp calibration LEDs on the input screen show two green indicator lights. Repeat the procedure for Projector 2 if applicable.

Pure waveform pattern with no text, numbers, or symbols

1. Double check the cell alignment by running a 100% STEREO ALIGNMENT fi lm. The amplitude of the two 100% modulated waveforms should be identical (see illustration). If one is greater than the other, while the modulated waveforms of the 50% level fi lm are identical, there is a problem with the scanning beam. Either the slit is not uniformly illuminated along its length or the scanning beam is not in perfect alignment with the fi lm guide rolle and solar cell. Since most soundhead optics cannot be moved in or out, it

will be necessary to reposition the fi lm guide roller and realign the solar cell, so that both the 50% and 100% modulated tones match from channel to channel. When this fi ne alignment is not done, loud sounds (above 50% modulation) will be distorted and wil leak into the surround channels.

1. Using the built-in Slit EQ Analyzer, run a pink noise test fi lm (Cat 69P or equivalent). Adjust the focus of the soundhead optics for the best high frequency response on the analyzer (see below). At the same time, adjust the azimuth for the thinnest display on the oscilloscope. The focus and az muth adjustments interact, so it will I necessary to keep adjusting both unt the best combination is achieved.

1. Using the built-in SLIT EQ Analyzer adjust the SLIT EQ slider until the response is flat to 12 kHz +/- 1 dB

8.3 Sum and Difference mode.

No Oscilloscope required.

When running a Cat 69P Pink Noise loop or the projector, precisely adjust the left and right projector gains so the red and green lines on the slit analyzer overlap.

Click "Normal" on the Slit EQ Analyzer. The button designation changes to "Sum & Diff Adjust the projector sound head so the two graphs are roughly parallel.

The top graph is controlled primarily by the focus of the reader. The bottom graph is controlled primarily by the azimuth.

First, the focus must be adjusted to achieve the best high frequency response for the top curve.

Most likely, the bottom graph will rise quickly at high frequencies. Carefully rotate the sound lens or reader until the curve is horizontal.

Note: It is a bit of a juggling act to keep rotating the reader and focusing it to achieve the best high frequency response on the top graph and the most horizont response on the bottom graph.

The graph below shows a reader with an azimuth error. The rising lower curve shows the phase difference between left and right channels. This is similar to a lissajous pattern on an oscilloscope where an ellipse indicates a poor alignment. The oscilloscope pattern is actually less accurate than the difference display. In the lissajous pattern, all the frequencies are added together so a phase difference at 20 kHz is less obvious. The difference display on the RTA shows the phase difference at each frequency

8.4 Mono EQ and Bypass Level

1. Click on the INPUT tab and select MONO format. Thread a pink noise loop on the projector. Using the SLIT EQ Analyzer, adjust the MONO EQ un the above curve is achieved.

1. Set the bypass level by adjusting trim-pot (1) until the voltage on the bypass level test point (8) reads 300 mV rms. Repeat the procedure for Projector 2 using trimpot (2). When the JSD-80 power switch is in the “off” position and the emergency backup power supply is present the main fader will control the bypass level.

8.5 Optical Surround Gain and Delay

1. Click the INPUTS tab and thread a Dolby Cat 151 test film on the projector.
2. Mute the screen channels and, using an RTA or SPL meter, adjust the SURR GAIN in the MATRIX CONTROLS so that the SPL level in the back matches the SPL level in the front. The SURR DELAY slider should be at 10 ms.
3. Calculate the surround delay by using the following formula:

Length of theatre - (width of theatre/2) +20 = Delay in ms

1. Set the SURR DELAY control accordingly.

8.6 Optical Subwoofer

See Section 9.5

8.7 Analog Non-Sync, AUX Levels, MIC Levels

1. Set main fader to 7.0. Connect the sound source to the NON-SYNC L and R RCA jacks. Click on the INPUTS tab. Select the NON-SYNC format. Adjust the left slide pot and both channels will change. The master fader should be set at 7.0.
2. Set main fader to 7.0. Connect the sound source to the AUX L and R RCA jacks. Click on the INPUTS tab. Select the AUX format. Use the main left and

right sliders outside the Preamp Calibration box to set the AUX level.

1. Connect a microphone to the DB-9 connector (pins 1+ and 2- with shield on 5). If the microphone is an electret type that requires 5 to 9 V DC you ma use pin 7 on the DB-9 for that power (see Section 12). Click on the Inputs tab and select the MIC format. Adjust the left slide pot and both sides will change.

1. Select the Formats tab and select Mic. Click the appropriate radio button to direct the Mic to center or surround channels.

8.8 Optional Digital Non/Sync, Digital Aux & Digital Eight-Channel inputs

Note: For these inputs to be active, the optional DI83 Module must be installed in the processor.

In the Format screen, select Non/Sync. "Input Type" will appear next to the format level slider. By selecting S/PDIF, a digital bit stream can be fed into the processor.

Note: The system supports either an analog or digital input for Non/Sync bu not both.

Typical input signals could be the digital coax output of a CD player, the digital coax output of a DVD player or a computer sour card. These outputs are typically "Orange" RCA jacks.

The processor also supports a S/PDIF Input in the Aux format.

Note: The system supports either an analog or digital input for Aux but not both.

When selecting S/PDIF, the Digital Delay be will appear below "Input Type." Since there is only one digital delay for AES/EBU, and S/PDIF inputs, setting this will affect all three digital inputs; (Ext 2, Non/Sync and Aux), the range is 0-100 ms input delay, 0-127 ms SURR delay.

The processor will accept stereo or AC3 data and decode 5.1 channels. The processor does not support DTS consumer bitstreams.

As with the AES/EBU input, if a fault occurs in the S/PDIF bitstream, the processor will mute. There are no emergency fallback formats for the S/PDIF inputs.

Note: For the AES/EBU inputs to be active, the optional AES/EBU module, DI83 must be installed in the processor.

The "EXT 2" digital domain input is configured for eight channels (four differential AES3 PCM data pairs with any sample rate from 32 to 96kHz ) See Section 12 for connector pinout specifications

Any AES3 PCM channel format ID bits (such as Pro/Consumer, Pre Emphasis, etc.) are ignored. If there is a fault in the AES/EBU data stream, the system reverts to a pre-selected emergency mode. This will occur if the AES/EBU word clock is lost or if the processor detects “non PCM” Data.

The DI83 module in this processor, which decodes Dolby® Digital bitstreams, is not intended for 35mm fi lm. The DI83 is intended for alternative content only.

To set the emergency digital fall back screen on the laptop interface, select "EXT 2" format. A box labelled "Digital Fallback" will appear. Simply select the emergency format desired. Selecting "EXT 2" will keep the processor in that format even though the audit may be muted. When the AES/EBU data is restored, the system will un-mute and continue to operate in the "EXT 2" format.

8.9 Digital Time Delays

When “EXT 2” is selected, a box labelled “Digital Delay” will appear. The “Input Delay” slider controls the overall time delay required to compensate for various video projectors. For example, a typical DLP projector requires about 80 ms delay. Consult your video projector manual for the exact delay required. The second slider controls the delay for the surround channels. The surround delay should be set by the following formula:

Length of theatre - (width of theatre/2) + 20 = Delay (in ms)

Note: After you are satisfied with the A Chain settings, you will want to save them to the unit. Refer to Section 9.5 for details.

Note: When the computer is connected to and controlling the JSD-80, the front panel controls will not function, with the exception of the Mute button.

9.1 Channel Confi guration

Selecting "File" in the menu bar will produce a drop down box. Click on "Input Configuration".

The processor supports either fi ve screen channels or "Ex" back surround channels but not both.

Select the appropriate configuration and click "OK".

Note: This configuration will affect the equalizer and format panels.

9.2 Headroom Settings

Selecting "File" on the menu bar will produce a dropdown box. Click on "Headroon Adjustment".

Select one of the three settings. Generally, 26 dB of headroom is sufficient provided there is not more than 6 dB total boost between bass and low frequency 1/3 octave filters or between treble and high frequency 1/3 octave filters. For instance, if the bass slider is set at +3 dB and any of the 1/3 octave eq bands from 40-125 Hz are boosted more than 3 dB, the headroom will be compromised.

Selecting 29 dB headroom would allow a full 6 dB bass boost plus up to +3 dB boost in any of the 40-125 Hz bands.

In each case, it is the total boost that impacts the headroom. For 26 dB, the maximum boost is 6 dB; for 29 dB, the maximum boost is 9 dB; for 32 dB, the maximum boost is 12 dB.

9.3 Main Channels

Left, Center, Right, Left Surround, Right Surround, (Left Center, Right Center or Back Surround Left, Back Surround Right).

Before proceeding with the room equalization it is imperative that the loudspeaker and crossover systems be properly aligned. Issues like speaker phasing and horn tilt need to be checked. When using crossover the low, mid and high frequency drivers must be balanced to produce a relatively even response from 100 Hz to 5 kHz.

1. Set up an external REAL TIME ANALYZER or the internal JSD-80 REAL TIME ANALYZER with the microphon two-thirds of the way back and one-third of the way in from the side of the auditorium. If a multiple microphone system is being used (such as the USI Inc. MMP-10), set up the microphones according to the instructions provide with that system. Set the MAIN FADEH to "7.0." Access the channel output controls on the Output panel on the JSD-80 Laptop Interface Software.

When aligning the auditorium for the first time with the JSD-80 Laptop Inte face Software, it is recommended to set all the channel gains to minimum, click the "Pink Noise" radio button in the Signal Generator box, click the "Pink" checkbox under the left channel slider, then exit the Output Screen to the Equalizer Screen for the frequency alignment.

Note: When using the generator, the default mode allows one active channel at a time. Holding down the control key allows selection of multiple channels fo

the generator (e.g., center and subwoof channels).

To use the internal JSD-80 REAL TIME ANALYZER, connect the microphone to the MIC input on the JSD-80. (See Section 12 for connector pin-outs.) With the pink noise generator turned on and the equalizer screen displayed on the laptop select the inputs screen. Note that the MIC input is selected. The auditorium microphone can be adjusted by using the MIC gain slider. Double click on the REAL TIME ANALYZER screen. A new window will open. Slide the window to the bottom of the laptop screen. Now select the equalizer tab and move the screen about the REAL TIME ANALYZER display

1. Slowly raise the level of the left channel power amplifier to its full on position. Now, slowly raise the gain slider until the SPL Meter indicates approximate 85 dB SPL (82 dB SPL for the surround channels).

1. Adjust the equalizer sliders until the response shown is obtained. Please note that once a slider is selected with a mouse click, the cursor pad up/dow keys will adjust the slider. The left/right keys will select the adjacent 1/3 octave slider. Use the bass and treble sliders to achieve the overall shape of the auditorium response. After making the

EQ adjustments, it may be necessary to fi ne-tune the output level setting

1. Repeat the tuning procedure for the center, right and additional channels. The JSD-80 includes a copy feature that minimizes the time required for this.

After equalizing the left channel, copy these settings to the center and right channels. Since all three front speakers are usually similar, if not identical, the EQ settings will be a close starting point. Similarly, after equalizing the left surround, copy these settings to the right surround channel

9.4 Subwoofer Channel

There are three separate subwoofer signal in the JSD-80. One subwoofer signal is created by summing the LT and RT channels on the two-channel input card. This signal has its own adjustable low pass fi lter and +/- 6 dB gain trim. The second subwoofer signal is a discrete input on the analog eig channel connector. The third subwoofer signal is a discrete input on one of the digi AES-EBU pairs. All the above signals pass through the main subwoofer parametric equalizer and channel gain.

1. Using the Equalizer Screen, select the Subwoofer channel radio button. Make sure the gain is set at the minimum, -22 dB. Slowly raise the power amplifier gain to maximum. Raise the channel gain slider on the JSD-80 software until the Subwoofer signal reaches roughly the same point as the center channel on the RTA.

1. Study the Subwoofer response on the RTA. The parametric will allow you to smooth the dips or take out bumps in the response from 20 to 100Hz . Adjust the FREQ slider to the same frequency as the peak. Set the Q control to about 4. Adjust the equalizer gain until response becomes flatter at the selective frequency. Adjust the Q control to widen the effect of the equalizer to achieve the best, fl attest response. It may be necessary to slightly readjust all the three controls until the best results are achieved.

1. Select the output screen and select both the center and subwoofer pink noise by holding down the "Ctrl" key and checking the boxes. The subwoofer should fill in the lowest frequency and create a smooth overall response on the RTA from 25 Hz to 1 kHz. It may be necessary to adjust the subwoofer channel gain. It also may be necessary to click to phase invert on the subwoofer to be sure that the low frequencies of the center and subwoofer are adding rather than subtracting. Set the final subwoofer level so that its horizontal display (20-100 Hz) is

10 dB ABOVE the horizontal display of the center channel on the REAL TIME ANALYZER.

9.5 Optical Subwoofer

1. Once the subwoofer channel is equalized and the level set, it is time to trim the optical subwoofer parameters.
2. Turn off the pink noise generator.
3. Thread a pink noise loop Cat 69 P or equivalent on the projector and select mono.
4. Set the optical subwoofer frequency to 50 or 60 Hz.
5. Using the auditorium microphone not the level of the pink noise from the center channel.
6. Adjust the optical subwoofer gain so the subwoofer output is on the same horizontal line as the center channel on the REAL TIME ANALYZER.

9.6 Saving Settings After Alignment

After completing the alignment, the configuration you have setup should be saved to the onboard DSP Flash RAM. To do this, choose the Disconnect icon from the toolbar or Disconnect from the Communication menu.

You will be prompted with the following screen providing several save options.

Clicking "Yes" will save your current settings to the JSD-80 and then verify that the were correctly saved to the unit. Choosing "No" will keep you connected to the JSD-80

unit allowing you to make more modifi ca- tions if needed. Choosing “Do Not Save” will disconnect from the unit and disregard all changes made for the current session. The unit will continue to retain the current settings until power is removed then the previous confi guration will be used

Checking the “Save to Personality Module” will save a backup of the entire unit configuration to the unit’s Personality Module. The personality module will provide a backup restore option in case of catastrophic processor failure. Make sure a Personality Module is present in the JSD-80.

Note: It is essential that when writing to the Personality Module, the Write Protect Switch is in the "OFF" (left) positio. Once the parameters are saved, however it is equally important that the switch b returned to the "ON" position.

Having a backup copy of all settings in the Personality Module permits loading a copy of all settings into a new replacement module without the need for a computer an technician.

10.1 Preset Format Levels

Click on the FORMATS tab. Select the form of interest. Adjust the "Format Level" on the panel to an appropriate setting.

Note: When changing levels in EXT 1 or EXT 2, remember to also change the Stereo SR level the same amount.

10.2 Startup Mode

Select the default startup mode from the li shown. Selecting NON-SYNC will cause the unit to "wake up" in non-sync every time it is powered up. Choosing "Last Selected" w cause the unit to resume its last operation format before it was powered down.

10.3 Remote Fader

1. The remote fader function can be accomplished with a simple pair of normally open switches. One button increases levels, the other decreases levels. The LED display on the JSD will indicate the change in discrete steps limited to 4.0 - 9.0.

10.4 System Restore

1. In the event of a catastrophic system failure, you may install the last con-

figuration saved to the Personality Module (1). If the control card is the module that has failed you will need to remove the Personality Module from it and insert it into the replacement control card from USL. If the input or output card has failed, you simply need to replace the failed one with a new module from USL. Once the replacement module is installed, you will hold down the restore button (4) as you power up the system. Hold the restore button until the "Restore" LED (5) begins to flash. Within thirty seconds, the "Restore" LED (5) stops flashing, the system is restored. Turn off the unit, wait 60 seconds and turn it back on. This procedure will restore the system without the need for a lap top or technician.

⚠️ Note: If you are replacing the contro module as a part of the repair process, remember to remove the Personality Module from the defective card and insert it into the replacement control module.

10.5 Format Options

This feature allows the technician to change some of the Format button/automation functions. By clicking on the Format Options box on the Formats tab on Laptop Interface Software the options are displayed for each of the Format selections.

The MONO, STEREO A, STEREO SR button can be configured with the following noise reduction options: "None," A Type, SR Type. The same buttons can also be configured with the following matrix decoding options: "5.1 Stereo," "2.0 Stereo," or "Mono." The 5 stereo option is the default setting. The 2.0 stereo option is for either Left/Right stereo or Center/Surround systems.

The EXT 2 button can be configured either for "AES-EBU" (Digital) or "Analog" inputs.

10.6 Wiring for an Electret Microphone

An Electret microphone can be connected to the JSD-80 using a DB-9 male plug as shown below.
