FEATURES
This unit incorporates a sophisticated, multi-program digital sound field processor. The processor allows you to electronically expand and change the shape of the audio sound field from both audio and video sources, creating a theater-like experience in your listening room. This unit has a total of 10 digital sound field processor (DSP) modes. You can create an excellent audio sound field by selecting a suitable sound field (this will, of course, depend on what you will be listening to), and adding desired adjustments.
In addition, this unit incorporates a Dolby Pro Logic Surround decoder and Dolby Digital (AC-3) decoder for multi-channel sound reproduction of Dolby Surround encoded video sources. The operation of the Dolby Pro Logic Surround or Dolby Digital (AC-3) decoder can be controlled by selecting a corresponding DSP program including combined operations of the Yamaha DSP and the Dolby Pro Logic Surround or Dolby Digital (AC-3) decoder.
Digital Sound Field Processing
What is it that makes live music so good? Today’s advanced sound reproduction technology lets you get extremely close to the sound of a live performance, but chances are you’ll still notice something missing, the acoustic environment of the live concert hall. Extensive research into the exact nature of the sonic reflections that create the ambience of a large hall has made it possible for Yamaha engineers to bring you this same sound in your own listening room, so you’ll feel all the sound of a live concert. What’s more, our technicians, armed with sophisticated measuring equipment, have even made it possible to capture the acoustics of a variety of actual concert halls, jazz clubs, theaters, etc. from around the world, to allow you to accurately recreate any one of these live performance environments, all in your own home.

Dolby Pro Logic Surround
This unit employs a Dolby Pro Logic Surround decoder similar to professional Dolby Stereo decoders used in many movie theaters. By using the Dolby Pro Logic Surround decoder, you can experience the dramatic realism and impact of Dolby Surround movie theater sound in your own home. Dolby Pro Logic employs a four channel five speaker system. The Pro Logic Surround system divides the input signal into four levels: the left and right main channels, the center channel (used for dialog), and the rear surround sound channels (used for sound effects, background noise, and other ambient noises). The center channel allows listeners seated in even less-than-ideal positions to hear the dialog originating from the action on the screen while experiencing good stereo imaging. Dolby Surround is encoded on the sound track of pre-recorded video tapes, laser discs, and some TV/cable broadcasts. When you play a source encoded with Dolby Surround on this unit, the Dolby Pro Logic Surround decoder decodes the signal and distributes the surround-sound effects.
This Dolby Pro Logic Surround Decoder employs a digital signal processing system. This system improves the stability of sound at each channel and crosstalk between channels, so that positioning of sounds around the room is more accurate compared with conventional analog signal processing systems.
In addition, this unit features a built-in automatic input balance control. This always assures you the best performance without manual adjustment.
Dolby Digital (AC-3)
The built-in Dolby Digital (AC-3) Decoder leads you into a totally new sound experiences.
Dolby Digital (AC-3) is a new generation of multi-channel digital audio technology, or the newest spatial sound processing format developed for 35 mm film-movies by employing a new kind of low bit-rate audio coding.
Dolby Digital (AC-3) is a digital surround sound system that provides completely independent multi-channel audio to consumers. In multi-channel form, Dolby Digital (AC-3) provides five full range channels in what is sometimes referred to as a “3/2” configuration: three front channels (left, center and right), plus two surround channels. A sixth bass-only effect channel is also provided for output of LFE (low frequency effect), or low bass effects that are independent of other channels. This channel is counted as 0.1, thus giving rise to the term 5.1 channels in total.
Compared to Dolby Pro Logic that is referred to a “3/1” system (left front, center, right front and just one surround channel), Dolby Digital (AC-3) features two surround channels, called stereo or split surrounds, each offering the same full range fidelity as the three front channels.
Sound of wide dynamic range reproduced by the five full range channels presents listeners much excitement that has never been experienced before. Precise sound orientation by the discrete digital sound processing expands realism that the original movie possesses.
6
Laser Disc is a home audio format that could benefit from Dolby Digital (AC-3). In the near future, Dolby Digital (AC-3) will also be applied to DBS, CATV, DVD and HDTV. The ongoing release of Dolby Stereo Digital theatrical films now underway will provide an immediate source of Dolby Digital (AC-3) encoded video software.

The following original functions make the surround-sound effect of Dolby Digital (AC-3) become the most suitable for your audio system and the listening conditions.
●Dynamic range (sound scale) of source can be changed so that it will be suitable for the listening conditions.
●Output of low bass from any channel can be assigned to either the MAIN SPEAKERS terminals or SUBWOOFER terminals to maximize system performance.
●Output of LFE can be assigned to either the MAIN SPEAKERS terminals or SUBWOOFER terminals to maximize system performance.
Dolby Surround + DSP (CINEMA DSP)
Dolby Surround sound system shows its full ability in a large movie theater, because movie sounds are originally designed to be reproduced in a large movie theater using many speakers. It is difficult to create a sound environment similar to that of a movie theater in your listening room, because the room size, materials of inside walls, the number of speakers, etc. of your listening room is much different from those of a movie theater.
Yamaha DSP technology made it possible to present you with nearly the same sound experience as that of a large movie theater in your listening room by compensating for lack of presence and dynamics in your listening room with its original digital sound fields combined with Dolby Surround sound field.
CINEMA DSP 7ch
The YAMAHA “CINEMA DSP” logo indicates those programs are created by the combination of Dolby Surround and YAMAHA DSP technology.

Dolby Pro Logic + 2 Digital Sound Fields
Digital sound fields are created on the presence side and the rear surround side of the Dolby Pro Logic Surround-decoded sound field respectively. They create a wide acoustic environment and emphasize surround-effect in the room, letting you feel much presence as if you are watching a movie in a popular Dolby Stereo theater.
This combination is available when the sound field program No. 2, No. 3 or No. 4 is selected, and the input signal of source is analog, PCM audio or encoded with the Dolby Digital (AC-3) in 2- channels.
Dolby Digital (AC-3) + 3 Digital Sound Fields
Digital sound fields are created on the presence side and the independent left and right surround sides of the Dolby Digital (AC- 3)-decoded sound field respectively. They create a wide acoustic environment and much surround effect in the room without losing high channel separation. With wide dynamic range of Dolby Digital (AC-3) sound, this sound field combination lets you feel as if you are watching a movie in the newest Dolby Stereo Digital theater. This will be the most ideal home theater sound at the present time.
This combination is available when the sound field program No. 2, No. 3 or No. 4 is selected, and the input signal of source is encoded with the Dolby Digital (AC-3) (except in 2-channels).

SPEAKER SETUP
Setting Up Your Speaker System
This unit has been designed to provide the best sound field quality with a full seven-speaker system setup, using two extra pairs of effect speakers to generate the sound field plus one center speaker for dialog. We therefore recommend that you use a sevenspeaker setup. A four-speaker system using only one pair of effect speakers for the sound field will still provide impressive ambience and effects, however, and may be a good way to begin with this unit. You can always upgrade to the full seven speaker system later. In the 4 or 5 speaker system, the Digital Sound Field Processing is still performed, but the main speakers are used for both the main channels and the front effect channels.
Use of the Center Dialog Speaker Is Recommended
When playing back a source with the DSP programs No. 1 through No. 4, or when the Dolby Digital (AC-3) is decoded with any DSP program used, if the source contains center-channel signals, dialog, vocals etc. are output from the center channel. Therefore, if you want to maximize the performance of your Audio/Video home theater system, it is recommended that you use a center channel speaker.
If for some reason it is not practical to use a center speaker, it is possible to enjoy movie viewing without it. Best results, however, are obtained with the full system.
Use of a Subwoofer Expands Your Sound Field
It is also possible to further expand your system with the addition of a subwoofer and amplifier. The use of a subwoofer is effective not only for reinforcing bass frequencies from any or all channels, but also for reproducing the LFE (low frequency effect) sound with high fidelity when playing back a source with the Dolby Digital (AC-3) decoded. You may wish to choose the convenience of a Yamaha Active Servo Processing Subwoofer System, which has its own built-in power amplifier.

This is the recommended speaker system, providing the best sound effects.
When a normal stereo source is played back with the sound field programs No. 5 through No. 10, using both sets of effect speakers (front and rear), reproduces the most effective sound field. When using the sound field programs No. 1 through No. 4 or when using any program with the Dolby Digital (AC-3) decoded, the center speaker provides precise center localization.

Speakers and Speaker Placement
Your full seven-speaker system will require three speaker pairs: the MAIN SPEAKERS (your normal stereo speakers), the FRONT EFFECT SPEAKERS and the REAR SPEAKERS, plus the CENTER SPEAKER. You may also be using a subwoofer.
The MAIN SPEAKERS should be high performance models and have enough power handling capacity to accept the maximum output of your audio system.
Other speakers do not have to be equal to the MAIN SPEAKERS. For precise sound localization, however, it is ideal to use high performance models that can reproduce sounds in full range for the CENTER SPEAKER and the FRONT EFFECT and REAR SPEAKERS.
Place the MAIN SPEAKERS in the normal position.
Place the FRONT EFFECT SPEAKERS further apart than the MAIN SPEAKERS, on either side of and a few feet behind and above the MAIN SPEAKER pair.
Place the REAR SPEAKERS behind your listening position. They should be nearly six feet up from the floor.
Place the CENTER SPEAKER precisely between the two MAIN SPEAKERS. (To avoid interference, keep the speaker above or below the television monitor, or use a magnetically shielded speaker.)
If using a SUBWOOFER, such as a Yamaha Active Servo Subwoofer System, the position of the speaker is not so critical because low bass tones are not highly directional.

2Standby Indicator
While the power of this unit is on, pressing the (SYSTEM POWER) OFF key on the remote control unit switches this unit to the standby mode. In this mode, the standby indicator is illuminated.
3Remote Control Sensor
Signals from the remote control unit are received here.
4Display Panel See page 16.
5Input Selector Buttons
Selects an input source that you want to listen to (and watch).
6Master VOLUME Control
Simultaneously controls volume level at all outputs: front effect, main, rear effect, center, and subwoofer. (This does not affect REC OUT level.)
*When the volume is decreased by pressing the MUTE key on the remote control unit, the indicator on the master VOLUME control flashes on and off.
7PHONES Jack
When you listen with headphones, connect the headphones to the PHONES jack. You can listen to the sound to be output from the main speakers through headphones.
When listening with headphones privately, set both the SPEAKERS A and B switches to the OFF position and switch off the digital sound field processor (so that no DSP program name is illuminated on the display panel) by pressing the EFFECT switch.
8SPEAKERS switches
Set the switch A or B (or both A and B) for the main speakers (connected to this unit) you will use to the ON position. Set the switch for the main speakers you will not use to the OFF position. Selected main speakers are shown by the lighting of “SPEAKERS A” and/or “SPEAKERS B” on the display panel.
9BASS EXTENSION Switch
When pressed inward (ON), boosts bass frequency response at the main left and right channels while maintaining overall tonal balance. If you do not have a subwoofer, the use of this switch will be effective to reinforce the bass frequencies.
0TONE BYPASS switch
When this switch is pressed inward (ON), the input signal does not pass through the tone (BASS and TREBLE) control circuitry so that it is unaffected by the tone control circuitry. Use this switch to obtain pure sound and to check the tone control setting. Press this switch to release it outward (OFF) to use the tone control circuitry.
ABASS and TREBLE Controls
Adjust low and high frequency response respectively for the main channels only.
BBALANCE Control
Adjusts the left and right output volume to the Main Speakers to compensate for sound imbalance caused by speaker positions or listening room conditions.
CREC OUT Selector
Selects the source to be recorded to a tape deck or
VCR independently of the setting of the input selector buttons. However, when set to the SOURCE position, the setting of the input selector buttons decides the source to be recorded to a tape deck or VCR.

English
19
REAR PANEL SWITCH AND CONTROL SETTINGS
There are several switches and controls on the rear panel that you’ll have to check before operating your system, and it’s a good idea to do it before you connect cables. Locate the MAIN LEVEL slide switch (C) and FRONT MIX slide switch (B). Make sure the MAIN LEVEL switch is set to “0 dB” and the FRONT MIX switch is set to “OFF” for 7 or 6 speaker driving.
In a 5 or 4 speaker system, set the FRONT MIX switch to “ON”.
Next, set the NTSC/PAL switch (A) to the position corresponding to the standard which your video equipment employs. (General Model only)
For the setting of IMPEDANCE SELECTOR switch (J), see page 29.
For the setting of the center speaker switch (6), see page 27.
GENERAL INSTRUCTIONS FOR
CONNECTIONS
Make sure that you have the left (L) and right (R) channels correctly connected. That means that jacks marked “L” on this unit must be connected to jacks marked “L” on other units. Likewise with the “R” jacks. This is easy if you remember to always use the red plug for the “R” jacks and the white plug for the “L” jacks.
For connections with audio/video source equipment, use RCA type pin plug cables with the exception described later.
With speaker connections you must also be sure that the polarity is correct. For each amplifier and each channel, connect the plus (+) terminal of the amplifier to the plus terminal of the speaker, and connect the minus (–) terminal of the amplifier to the minus terminal of the speaker. To keep track of polarity, use a speaker cable that has one of the two wires marked by a stripe or a different color.
