These buttons choose the desired input source (device connected to CD, AUX1, AUX2, 5.1CH, OPTICAL, COAXIAL (14)(15)(16) or the built-in TUNER) that you want to change to.

1. AM, FM If the receiver input "TUNER" has been chosen, this button switches between AM and FM mode. A suitable antenna must be connected to the corresponding antenna input (12)(13).

26. Number block for the control of the Tuner

Number pad (0-9) for direct frequency input or selection of presets in Tuner mode.

1. ST/MONO If the receiver input "TUNER" has been chosen, you can switch between stereo and mono reception of radio stations. If a station's signal quality is low in stereo mode, a change to mono mode may result in better sound quality.
2. DIRECT If the Tuner has been selected as input source, after pushing this button you can enter a known radio station frequency directly by using the number buttons (26).
3. MEMORY If the receiver input "TUNER" has been chosen, this button is used to store a previously selected radio station frequency to one of the memory presets. The procedure is described in the chapter „Operating the receiver - Tuner".
4. TU.MODE If the Tuner has been selected as input source, you can use this button to choose between three settings that determine what function the buttons TU / PR (32) will have: "MANUAL" (manuel frequency scan), "AUTO" (automatic frequency scan) oder "PRESENT" (search the tuner preset stations stored previously).
5. A.MUTE If the receiver input "TUNER" has been chosen, a volume muting that will be applied in manual tuning mode can be activated or deactivated using this button. It removes the noise at frequencies between the stations.

1. TU / PR If the receiver input is set to "TUNER", you can select a radio station with these buttons. What function they will have is determined by the setting that has been done by pressing "TU.MODE" (30).
2. RDS If the receiver input "TUNER" has been chosen, this button activates, deactivates and changes the different possible RDS services. RDS is available from some FM radio stations and provides the listener with text information seen in the front panel display (2).

3. PROLOGIC, 3-ST, STEREO These three audio playback modes (D. Prologic, 3-Stereo, Stereo), based on the stereo format, are also selectable using the "LISTEN" button [37] and can be directly chosen here.

4. IN.MODE Select the way the receiver will try to decode digital audio signals (e.g. DD, PCM) at the inputs "OPTICAL" and "COAXIAL" (14). Best choice is the setting "AUTO MODE".
   See chapter "Operating the receiver - General functions".

5. CHANNEL In combination with the „SET“ buttons (38) this can modify the volume difference between the speaker channels (front left, center, etc.). For the front channels this is equivalent to the “Balance” setting of stereo systems.
   See chapter "Speaker settings - Setting and testing the volume of the speaker channels".
6. LISTEN For every type of audio input signal (for example „Stereo analog“) there are several possible audio playback modes (for example „STEREO“, „3 CHANNEL STEREO“ or „PROLOGIC“). Using this button you can choose between them. The buttons (34) can be used to select those three playback modes directly. See chapter „Operating the receiver - Audio playback modes“.
7. SET - buttons "SET+ and SET" have identical function as the knob MULTI CONTROL (9) at the front panel. In normal operation these but tons serve to switch to a different input channel. In settings mode (TONE, CHANNEL, SPEAKER, DSP and some tuner modes) they are used to browse available parameters.
8. SPEAKER In combination with the "SET" buttons (38) this is used to set up the speaker configuration for optimizing the sound management system. See chapter "Speaker settings - Speaker configuration".
9. VOL+ und VOL- Adjust with these buttons the volume level of speakers, phones and the signal of the preamplifier outputs „PRE" (19) and „SW" (18).
10. MUTE, If this button is pressed, the volume of speakers, phones and the pre-amplified outputs "SW" (18) and "PRE" (19) is forced to zero. If pressed again, the original volume levels are being restored.
11. DELAY After installing a speaker set, delay times for surround and center (Dolby Digital only)

channel signals must be adjusted, optimizing the sound of "Dolby Digital" and "Prologic" material. The "SET" buttons (38) are being utilized.

Low-volume movie dialogues become comprehensible at low system volume levels while high-volume sound effects represent no disturbance to others any more.
5. TEST Upon activation, a test noise sound changes through all speaker channels. It enables you to check the differences in volume levels of all speaker channels at your listening/viewing position in the room. One more touch of the button turns off the noise signal. See chapter "Speaker configuration - Setting the volume of the speaker channels".
6. DSP Repeated use of this button changes through all eight possible sound conditioning formats and sound simulation modes like "Hall" or "Pop". See chapter "Operating the receiver - Digital simulating effects".

INSTALLATION

Home theater systems can reach different levels of complexity. Using this receiver, the system can consist in a minimal configuration of a DVD-Player, this receiver, one TV and a speaker set. If it is desired to use most of the potential of the AV receiver, it becomes harder to handle the system configuration with lots of components.

Imagine your AV system a general system that is provided with input signals (via its input connectors) and makes output signals available to components connected to its output connectors.

The receiver's function is to process the audio video signals from different sources (CD, DVD, TUNER) connected to the inputs and to supply them via its outputs to the components connected there.

It becomes clear that it is possible to guide the video signal directly to the displaying device and thus not feeding it through the receiver. This may be of use if you have connected only one video source device. In doing so you eliminate the (extremely small) loss in video quality that every unnecessary processing of signals creates. This solution is also useful if you want to use the coaxial digital audio connection from the AV-source, because this receiver input is audio-only. The advantage you have when feeding video signals through the receiver is its capability of switching audio and video signals of different inputs simultaneously.

Establish the necessary cable connections for all inputs first. Then add the outputs' cable connections. The last thing to do is to provide power by adding the power cable.

General instructions:

Note that there is no signal conversion between the two video signal formats S-Video and Composite. The displaying device will be able to display only the signals of video sources that use the same type of connection! It is always possible to connect video signals of AV sources that use a different type of video output directly to the displaying device (TV, video beamer).

Note that "COAXIAL" is an audio-only input. If you want to use it for an AV source as a DVD-Player, the video signal must be connected directly to the displaying device (TV, video beamer) as mentioned above. You can use all audio-only inputs (such as CD, AUX2") of the receiver for AV-sources that way.

Remove plastic protective covers

Prior to the first installation, remove the plastic protective covers on all used connectors.

Connections

Most of the input, output, audio and video connectors are mechanically identical RCA jacks. Pay attention to connect the cables to the associated ones!

Connection quality

Make sure all connections are tight. Loose connections may cause noise, failure or malfunctions.

RCA Connection

Do not interchange connectors for right and left channel. At most audio equipment, RCA connec

tors are color-coded

using red for the right channel and white or black for the left channel.

Loudspeaker Connection

Use speaker cables with connectors (for example banana connectors) for safety.

Make sure that unprotected speaker cable ends can not touch each other or the metal of the receiver housing!

Connect only one speaker cable wire to one screw connector!

Mind the polarity of the speaker cable. Match it to the polarity of the screw terminals (positive = red = marked side of the cable). If one speaker has false connection polarity, sound quality reduces dramatically.

Use only speakers with a nominal impedance of not less than 4

Interconnection Cables

To achieve best performance only quality interconnection cables as produced by Vincent should be utilized. Prefer shielded audio cables. Consult your audio specialist dealer.

INPUT CONNECTIONS

Name of input channel	Type of audio input and connector	Type of video input and connector
CD	stereo analog (RCA)	-
AUX 1	stereo analog (RCA)	Composite (RCA) or S-Video (Mini-DIN)
AUX 2	stereo analog (RCA)
5.1 CH INPUT	5.1 analog (RCA)	Composite (RCA) or S-Video (Mini-DIN)
OPTICAL	5.1 digital (Toslink)	Composite (RCA) or S-Video (Mini-DIN)
COAXIAL	5.1 digital (RCA)	-
Antenna (Tuner)	Antenna 75Ω/loop antenna	-

Audio inputs of "CD", "AUX1", "AUX2" and "5.1 CH" represent standard analog high level audio inputs using RCA jacks.

CONNECTING AUDIO/VIDEO SOURCES

To provide your audio system with the input signals (from DVD-Player, CD-Player, Tape etc.), connect their outputs and the antenna to the inputs of this receiver.

The table on previous page shows you properties and affiliation of the connectors. For information about connectors on your source devices refer to their manuals.

For utilization of a record player mostly a separate phono pre-amplifier is needed. It must be situated in the signal path between record player and one receiver stereo high level input. Most types are RCA-connected. Some models integrate this small amplifier unit and can be connected directly to the receiver. For more information see the manual of the record player.

First, connect all devices that can deliver multi channel audio. Inputs "COAXIAL", "OPTICAL" (14) and "5.1 CH" (16) can be used for those. Check the available connection standards at those devices to decide which receiver input to choose, respectively. Up to three multi channel sources can be connected to the receiver. If you should want to connect less than three multi channel sources, the free ones can be assigned to stereo sources. Should you decide to connect more than three multi channel sources, it is possible to establish a stereo connection to one of the receiver's free stereo input channels.

Second, connect all unassigned stereo source devices with free receiver stereo input channels. Again, the previous table can show you which receiver input channels can be used as AV inputs.

In the following you can see some typical setup situations:

CD-Player and other Stereo Audio-Sources

Stereo Audio-Source with Video connection

Analog Audio Multichannel Source

Digital Audio Source with optical signal connection
Digital Audio Source with coaxial signal connection

CONNECTING THE ANTENNA

If a wall terminal that provides radio signal from satellite, house antenna or cable is available in the room, connect its radio socket with the "FM 75 jack (12). Otherwise you could use an indoor aerial or the provided lead-type FM antenna (wire). Fit the metal sleeve of the lead-type antenna over the core (center) pin of this connector.

If you want to receive AM broadcast, connect the loop antenna's wires to the AM antenna terminals "LOOP ANTENNA" (13) as shown.

OUTPUT CONNECTIONS

CONNECTING SPEAKERS AND THE SUBWOOFER

Two front speakers (right and left), one center speaker, two rear (surround) speakers and one passive or one active subwoofer can be used in the system based on this receiver. Every speaker is connected to its assigned pair of screw/banana connectors. If you are using an active subwoofer, it must be connected to the RCA output "SW" (18) instead.

CONNECTING SPEAKERS

Consider correct polarity, the positive contact is mostly marked red or with " + " . The side of the speaker cable that has to be connected with the positive socket has a marking.

If you use speaker cable equipped with connectors, all you need to do is connect the two plugs of each speaker's associated cable to the correct screw terminal jack.

Otherwise, remove a piece of approximately 1cm from the cable insulation at the cable ends, twist the blank cable ends and turn the speaker connector screw counterclockwise to release it. Insert the blank wire into the hole in the screw thread. Turn the screw connector clockwise to fasten the speaker cable.

Your receiver has two output connectors dedicated to the subwoofer signal: One speaker screw terminal in the "SPEAKERS" field for a passive subwoofer and one line level output for an active saubwoofer. An active subwoofer includes a built-in amplifier, a passive one not. You can recognize active subwoofer by their power supply cable or power supply connector at the rear panel. It is not necessary to connect a passive and an active subwoofer at the same time. An active subwoofer's RCA cable must be connected to the output "SW" (18) subwoofer jack (mono). When using a passive subwoofer, connect it to the associated speaker screw (banana) connectors "SW" (22) instead.

CONNECTION TO A RECORDING DEVICE

If that is desired you can connect an analog stereo recording device like a CD-Recorder or a tape recorder to the receiver's "REC" (17) RCA connectors. It delivers the unchanged, fixed stereo level (line level) of the source device that is connected to the SV-122 and currently selected. This output level is independent from the volume and mute settings.

Connect this signal output of the preamplifier using RCA cables to the signal input (,RECORD^ or ,INPUT^ ) of the recording device. It is possible to connect other devices that accept the line level signal of the source that is selected at the receiver (for example integrated amplifiers).

AV recordings can be made if the receiver's video output is connected to the video input of the recording device instead of a displaying device.

STEREO PREAMPLIFIER OUTPUT "PRE"

These stereo RCA connectors (19) are only needed, if you want to add one or more main amplifiers for additional speakers.

This could be of use if you want to listen to stereo music with higher-quality speakers and use a compact cinema surround speaker set for movies.

CONNECTING A DISPLAY (TV,VIDEO BEAMER,ETC.)

The receiver owns two video output connectors (21): one for Composite Video (RCA) and one for the S-Video (Mini-DIN) signal type. The last mentioned transmits separate color and brightness signals and thus has higher picture quality compared to Composite video.

All display devices that accept one of those signal and connection types can be used with this receiver. The most used displays are TV and video beamers.

If the displaying device has additional video inputs, they can be used to accept the video signals of source devices that have audio connection with the SV-122 receiver.

CONNECTING HEADPHONES

A set of headphones equipped with a standard 6.3mm plug can be plugged into the "PHONES" jack (11) (stereo, analog) at the front panel. As long as a headphone is connected, the speakers and the preamplifier outputs "PRE" (19) and "SW" (18) of the system are muted. We recommend setting the

audio playback mode to "STEREO" when listening to headphones. Before the headphone connector is inserted or removed, the volume level should be reduced. All headphones can be used starting from an impedance by 32 ohms.

To establish the power supply push the plug of the power cable into the AC socket on the back panel and connect the plug on the other side of the cable to

a 220 V - 240 V AC 50 Hz wall outlet. Make sure that a current of 10 A can be provided

SPEAKER SETTINGS

Home cinema systems are designed for a variety of combinations with other consumer electronics and many different environments. That is why it is necessary to configure the system before first use and every time the speaker system is changed.

Usually, a quick setup procedure must be absolved, where audio/video settings have to be made. This setup has been reduced to the minimum required steps at this receiver, to kepp it user friendly. No video settings have to be taken on for this receiver. So only the speaker configuration and the required volume differences and delay times have to be defined. Note that some settings can only be made using the remote control.

It is best to follow the sequence displayed in the following table:

Button(s)	Function	At front panel/with remote control	available parameters
1 SPEAKER (6)(39)	Speaker configuration	both	SMALL LARGE NONE
2 CHANNEL (5)(36)	Stereo bal. and vol. level difference of center, surround and subwoofer signals in relation to front channel volume level	both	Speaker channel volume differences in dB
TEST (47)	The speaker channel test sound ("TEST" (47)) can make volume level differences experienced at the listening position recognizable	remote control only
3 DELAY (42)	Delay times of the center and surround signals in relation to front channel signal	remote control only	Delay time in ms (milliseconds)

1 SPEAKER CONFIGURATION ( „SPEAKER“ BUTTON)

These settings influence the distribution of the source signals to the different speaker channels. Since every surround sound system needs „bass management" to bring bass frequencies from specific or all channels to those speakers that are best adapted for the reproduction of those, it is necessary to give the receiver information about the kind of speakers used.

As „SMALL" speakers all speaker models without nameable bass (frequencies below 80Hz ) playback ability are declared, irrespective their size. „LARGE" speakers are all used speakers that have the ability to playback low bass frequencies. No speaker (.,NONE^ ) means that it is not used in the system. If, for example, no rear surround speakers have been installed, the required setting is „NONE".

At any time in normal operation you can enter the speaker configuration menu pressing „SPEAKER" (6)(39). Do this after first installation and every time you add, remove or exchange speakers.

If the „5.1 CH INPUT" is currently selected, it is not possible to change these settings.

If no button is pressed for some seconds, the normal operation mode (display of currently selected source input) is entered again. While settings mode is still active, the following settings can be made using "MULTI CONTROL" (9) or the "SET" buttons (38) on the remote control.

By using the button „SPEAKER" (6)(39) you select speaker categories, parameters can be changed using the knob „MULTI CONTROL" (9) or the remote „SET" buttons (38). The settings mode will be left automatically. Make your settings as described in the following:

All Speaker settings are "global", they have effect on all source input channels except .5.1 CH INPUT and in all sound playback modes.

2 SETTINGS AND TESTING THE VOLUME OF THE SPEAKER CHANNELS (CHANNEL" AND ,TEST BUTTON)

In most cases the viewing/listening position must be chosen in a way that the distances to the different speakers are not equal. Additionally, efficiency of different speaker types varies, so that the experienced volume level at identical signal at the speaker output can be very different. This can reduce or undo the „surround“ effect of films. To avoid that, every speaker channel is separately adjustable in volume level.

If "5.1 CH INPUT" has been selected, these settings can not be changed.

If a source input channel with stereo audio format (CD, AUX1, AUX2, TUNER) has been selected, the volume level differences of the rear channels and the center channel (LS, RS und CEN) can not be changed.

Settings for speaker channels that are defined „NONE" or „N" in the „SPEAKER" (6)(39) menu can not be changed.

If a source input with digital audio ("OPTICAL" und "COAXIAL" (14)) has been selected, volume level differences of the rear channels and the center channel (LS, RS und CEN) can not be changed when a PCM stereo signal has been detected by the receiver or if one of the stereo-based sound playback modes ("STEREO", "3STEREO" and "PROLOGIC") has been selected.

Make sure the system volume level is at a low value. Activate the test sound using the "TEST" button (47) while staying at your favourite viewing/listening position in the room. A hissing noise can be heard changing through all used speaker channels that have not been deactivated in the "SPEAKER" (6)(39) settings menu. Check which speaker channel volumes, compared with the front left channel, have to be increased or decreased.

L C R SR SL SW

Press "TEST" (47) to deactivate the test sound. Press CHANNEL" (5)(36), repetitive use changes the settings display through all selectable speaker channels. Using the knob ,MULTI CONTROL" (9) at the front panel or the "SET" buttons (38) on the remote control, you can now eliminate differences in perceived volume levels. Levels can be attenuated or amplified up to 10dB. Settings mode will be left if no input is made for a few seconds. Check again, if all speaker channels have the same volume level at the listening position. The following scheme shows the menu options:

All settings are "global", they have effect on all source input channels except ".5.1 CH INPUT" and in all sound playback modes.

3 SETTINGS THE DELAY TIMES OF THE SPEAKER CHANNELS (DELAY" BUTTON)

In order to achieve a homogeneous sound field at your position in the room, it is necessary to adjust the delay time values for the rear speaker channels and the Center speaker channel. This is necessary, because in a speaker arrangement typical for a living room the front speaker distance to the listening position is usually larger than the rear speaker distance to the listeners. Irritations of the perception of direction by early surround signals are avoided by delaying the signal for the rear speakers. In some speaker arrangements a delay time must also be adjusted for the center speaker. As the result the sound signals of all speakers arrive at the listener at the same time. In the mode „PROLOGIC", additional 15ms (milliseconds) of delay cause the back channel sound to arrive later than the front channel sound. This is part of the "Dolby Surround Prologic" specification and reduces audibility of sound fractions crosstalk from the front channel signals and makes sure that the audio information, that is important for sensual location of acoustic sources, is first obtained from the front channels. This receiver allows Surround delay times from 0ms to 15ms (milliseconds) in the „Dolby Digital" mode and from 15ms to 30ms in the „Prologic" mode. Additionally, in the „Dolby Digital" mode, a Center delay time in the range 0ms...5ms must be set. All this has to be done after first installation of the system and to be repeated every time the speaker distances are changed.

Calculating the delay time values

Surround delay for Dolby Digital mode: Measure the distance from your listening position to the front left or right speaker. Substract from this value the distance from the listener's position to the rear speakers. Each 30cm of this difference should be related with a delay time of 1ms. Round to the closest multiple of 30cm . For example, a length difference of 120cm results in a required delay time of 4ms. The maximum value is 15ms.

Center delay for Dolby Digital mode: Measure the distance from your listening position to the Center speaker and to one of the front speakers. Subtract the Center distance from the Front speaker distance. Again, 30cm of this difference should be related with a delay time of 1ms. Round to the closest multiple of 30cm . If the Center speaker is about 50cm closer to the listener, 2ms of delay time should be applied. The maximum value is 5ms.

Surround delay for Dolby Prologic II mode: Add 15ms to the Surround delay time in Dolby Digital mode.

Setting the Dolby Digital delay times

Choose one of the receiver inputs with digital sound (OPTICAL, COAXIAL (14)). Use the button "LISTEN" (3)(37) to enter playback mode "Dolby Digital". Press the "DELAY" (42) button.

SDLY --ms Use the „SET" buttons (38) to change the parameter for the rear (surround) speaker channels to the calculated value for Dolby Digital. Press the „DELAY" (42) button again and enter the calculated value for the center channel delay using "SET" (38).

CDLY --ms If no input is given for a couple of seconds, the settings mode is quit into normal operation.

Setting the Dolby Prologic II delay time

Choose one of the receiver inputs except for „5.1 CH". Change the audio playback mode to „PROLOGIC" using the "LISTEN" (3)(37) button (do not use the button „PROLOGIC" on the remote control). Press „DELAY" (42).

SDLY --ms

Use the "SET" buttons (38) to change the parameter for the rear (surround) speaker channels to the calculated Dolby Prologic II value. If no input is given for a couple of seconds, the settings mode is quit into normal operation.

These changes can only be made while audio playback modes "PROLOGIC" or "DB DIG" (Dolby Digital) are selected.

Settings for Dolby Digital and Prologic are saved and stored separately.

If "5.1 CH INPUT" has been selected, these settings can not be changed.

To keep disturbances to other people in quiet environments to a minimum, many home cinema systems offer a function like „Night" . Quiet sounds are intensified, loud passages are dampened. That enables you to comprehend movie dialogues at low system volume levels while high-volume sound effects represent no disturbances to others.Activate this option by a short push on the „NIGHT" button, if repeated, the "night mode" will be deactivated.This function can be activated and deactivated only from the remote control and is only available in the audio playback mode "Dolby Digital".

Audio playback modes ("LISTEN" button)

The SV-122 can accept different types of audio signals. Digital formats can be identified by the receiver and a suitable playback mode is changed to automatically if the input mode (IN_MODE) is set to "AUTO MODE". For all audio formats different playback modes are possible. At one time it could be preferred to listen to stereo sources using only front speakers and the subwoofer, at another time playback using the whole set of speakers may seem more attractive. The button "LISTEN" at the front panel (3) or on the remote control (37) as well as the buttons (34) serve to choose the audio playback mode.

Bear in mind that the subwoofer will always have a signal if it is activated in the „SPEAKER" menu.

If "5.1 CH INPUT" has been selected, these settings can not be changed. In this case, the receiver will output those signals that it receives at each channel's input connector.

DIGITAL SIMULATING EFFECTS

DSP is especially effective with material from CD, TV and FM radio. Just try different DSP-Modes when using the receiver to listen to a concert or watch a sports broadcast!

Repeated use of the „DSP" (7)(48) button changes the used DSP-mode:

The simulation of different environments is created by adding reverberation and changing the frequency content of the sound signal without degrading the signal quality.

The DSP mode "LIVE" creates the atmosphere of a Live-Concert at the playback of different input sources.

If the receiver input "5.1 CH INPUT" is selected, DSP programmes can not be used.

TIPS

Burn in/ Warm up

Your audio components need a certain time period until they reach maximum performance. The duration of this "warm up" time is very different for the various elements of your audio system. Higher and homogeneous sound quality is achieved while keeping the device switched on.

Your audio specialist dealer has enough experience to give you more information.

Net frequency noise

Some audio source devices may together with the amplifier cause a humming noise at powerline frequency audible from your speakers. Usually its volume is variable with the volume setting of the amplifier. This is no sign of a defect or fault of your audio products but has to be eliminated.

Generally, every wall-powered device connected to the ground wire of the power plug can cause this problem when connected to the amplifier.

Mostly that this problem is caused by antenna-connected components (as TV-sets or Tuners), personal computers, electrostatic loudspeakers, subwoofer, record players or headphone amplifiers that are connected to the audio inputs of the amplifier. Another possible reason for humming noise is electromagnetic interference of other components' power supplies with pick-up-systems of record players (change the place of the record player for a test).

Some main amplifiers are equipped with a „Ground Lift“ switch. If it is activated, ground potential of the chassis and the protective ground wire are being separated from the central signal ground point. The protective ground wire keeps its function. Sometimes this helps prevent noise caused by errors in grounding.

If the problem occurs and cannot be solved by you-self your audio specialist dealer will help you.

GLOSSARY

RCA (Cinch)

Name of a coaxial two-pole plug-and-socket connection (abbrev. for "Radio Corporation of America", name of a US-American company). Plugs and sockets are built from a middle pin conductor and a concentric metal cylinder mantle as the outer conductor. One signal, audio or video, can be transferred. Compared to XLR, this type is being called "unsymmetrical signal connection" ("unbalanced").

Input sensitivity

Term used for the smallest input voltage that makes the amplifier generate the maximum output power at maximum volume setting. Examples: 100 to 500 mV (Millivolts) at high level inputs, 2 to 5 mV at Phono-MM-Inputs or 0,1 to 0,5 mV at Phono-MC-Inputs.

Audio sources / Audio source device

Components of your Hi-Fi system and devices that deliver the audio signal you want to listen to, for example CD-Players, Tuners, Tape recorders, DAT Recorders, Personal Computers, Record players, portable audio devices and many more.

Dolby

A company located in the Bay area near San Francisco (Dolby Laboratories, Inc), named after its founder and president Ray Dolby. In the recent

decades this company developed many technologies and signal processing standards for the improvement of audio playback and recording. Most famous products are „Dolby NR" (noise reduction for audio tape playback), „Dolby Surround Prologic" (analog multi channel audio standard) and „Dolby Digital" (digital multi channel audio standard).

Dolby Surround Prologic

Dolby Prologic is an analog four-channel audio system including two front channels, one center channel and one surround channel. The signals of both additional channels are integrated in a clever way into the Stereo signal (of VHS-Cassettes, LD's und DVD's, as well as diverse TV programmes), so that even conventional equipment, that cannot process surround sound, can use the integrated stereo sound as usual. A decoder separates the four channels. The Dolby Surround Prologic sound quality is not perfect: the surround channel ist monophonic and has a cut frequency range of 100 to 7000Hz . Moreover, as opposed to the digital surround systems a considerable crosstalk into both additional channels is present.

Dolby Prologic II (5.1)

From conventional two channel signals, for example digital PCM, analog Stereo or Dolby Surround Prologic signals 5.1 separate channels are calcula

GLOSSARY

ted. All Dolby Surround software offered up to now contains decoders for Prologic II. As opposed to Prologic the full HiFi frequency range is covered for all channels and there are two surround channels.

Dolby Digital 5.1 (AC-3)

Dolby Digital 5.1 (firstly named AC-3) is a digital audio multi channel format developed in 1992 for the movie sound recording and playback in the Dolby Laboratories. It contains up to six independent channels (two front channels, one center channel, two surround channels and one low-frequency channel (LFE)). The first mentioned five channels can transfer the full audible frequency range (20 to 20,000Hz ), the LFE channel only the low bass frequency range (20 bis 120Hz ). All separate digital signals are interleaved into one digital data stream

that can be transferred via ONE digital cable. Compression techniques are used to reduce the huge data rate necessary for this high quality signal data transfer by the factor of eight. The effective data rates are 384 and 448 kbit/s. Since 1997 Dolby Digital 5.1 is the standard DVD audio format.

DSP

stands for "Digital Signal Processor". This is a small microcomputer (IC, chip) designed for the processing of digital signals (audio or video). It can, for example, be used to add reverberation or echo to an audio signal. One of the most important factors in the perception of sound is reverberation, that is the way how the sound is reflected continuously by different objects and walls (similar to echoes) in the room.
