Notes about the Remote Control Unit

When you notice that remote control operation has become erratic, or the distance from which the remote control will function has decreased, it’s time to replace the batteries. Always replace all batteries at the same time.

• If you have exchanged batteries in the remote control unit with new ones, press the RESET button before using the remote control unit.

Make sure that the YPC/USER/LEARN switch on the remote control unit is set to the YPC or USER position for normal operation.

This remote control uses an advanced, highly directional infrared beam. Be sure to aim the remote control directly at the remote control sensor on the main unit when operating. Open/close the control door When it is not necessary to operate controls inside the control door, close the door. To open the door Remote control transmitter operation range To close the door Remote control sensor Within approximately 6 m (19.7 feet) 30°

30° Notes There should be no large obstacles between the remote control transmitter and the main unit. If the remote control sensor is directly illuminated by strong lighting (especially an inverter type of fluorescent lamp etc.), it might cause the remote control transmitter to work incorrectly. In this case, reposition the main unit to avoid direct lighting. FEATURES In addition, this unit incorporates a Dolby Pro Logic Surround decoder and Dolby Surround AC-3 decoder for multi-channel sound reproduction of Dolby Surround encoded video sources. The operation of the Dolby Pro Logic Surround or Dolby Surround 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 Surround 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. English 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 12 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.

Dolby Pro Logic Surround Dolby Surround AC-3 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 lessthan-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 surroundsound effects. The built-in Dolby Surround AC-3 Decoder leads you into a totally new sound experiences. 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. Compared to Dolby Pro Logic that is referred to a “3/1” system (left front, center, right front and just one surround channel), Dolby Surround AC-3 features two surround channels, called stereo or split surrounds, each offering the same full range fidelity as the three front channels. In addition, this unit features a built-in automatic input balance control. This always assures you the best performance without manual adjustment. 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. Dolby Surround 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 Surround AC-3 is a digital surround sound system that provides completely independent multi-channel audio to consumers. In multi-channel form, Dolby Surround 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.

Copyright 1992 Dolby Laboratories, Inc. All rights reserved. The following original functions make the surround-sound effect of Dolby Surround 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. 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. English Laser Disc is a home audio format that could benefit from Dolby AC-3. In the near future, Dolby 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 AC-3 encoded video software. 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.

• Output of LFE can be assigned to either the MAIN SPEAKERS terminals or SUBWOOFER terminals to maximize system performance.

Dolby Pro Logic + 2 Digital Sound Fields Dolby Surround AC-3 + 3 Digital Sound Fields A digital sound field is created on the presence side and the rear surround side of the Dolby Pro Logic Surround-processed sound field individually. 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. A digital sound field is created on the presence side and the independent left and right surround sides of the Dolby Surround AC3-processed sound field individually. They create a wide acoustic environment and much surround effect in the room without losing high channel separation. With wide dynamic range of 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 used on sound field programs No. 7 through No. 11, and “PROLOGIC/Enhanced” of No. 12. This combination is available on the sound field programs No. 7 through No. 11 and “AC-3/Enhanced” of No. 12 when playing a source with the Dolby Surround AC-3 decoded.

• If you connect your video cassette recorder, LD player, video monitor, etc. to this unit, you can take advantage of this unit’s capability to display program titles, parameter data and information for various setting changes and adjustments on your video monitor’s screen.

SPEAKER SETUP Setting Up Your Speaker System Use of the Center Dialog Speaker Is Recommended 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. When playing back a source with the “CINEMA DSP” programs No. 7 through No. 12, or when the Dolby Surround AC-3 is decoded with any DSP program used, 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 Surround AC-3 decoded. You may wish to choose the convenience of a Yamaha Active Servo Processing Subwoofer System, which has its own builtin power amp.

4 Speaker System 5 Speaker System 6 Speaker System 7 Speaker System Simplest system. Good for Audio/Video sources. Good for sound fields from 2-channel stereo sources. This is the recommended speaker system, providing the best sound effects. You can enjoy widely diffused sound by only adding two additional speaker units at the rear. By the use of center speaker, center sounds (dialog, vocals etc.) are precisely localized. When a normal stereo source is played back with the sound field programs No. 1 through No. 6, a sound effect matching that of a 7-speaker system can be obtained. The addition of front left and right effect speakers produces a more effective sound field. When a normal stereo source is played back with the sound field programs No. 1 through No. 6, using both sets of effect speakers (front and rear), reproduces the most effective sound field. When using the the sound field programs No. 7 through No. 12 or when decoding the Dolby Surround AC-3 with any program used, the center speaker provides precise center localization. FRONT MIX switch—Set to ON. (See page 21.) CENTER SP—Set to PHNTM. (See page 30.) FRONT MIX switch—Set to ON. (See page 21.) CENTER SP—Set to NRML or WD. (See page 30.) FRONT MIX switch—Set to OFF.

English Four Possible Types of Speaker System Configurations Recommended

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 EFFECT 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 and REAR EFFECT 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 EFFECT 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.

GENERAL INSTRUCTIONS FOR

CONNECTIONS 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 (D) and FRONT MIX slide switch (C). 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. 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. In a 5 or 4 speaker system, set the FRONT MIX switch to “ON”. English

REAR PANEL SWITCH AND CONTROL

SETTINGS For connections with audio/video source equipment, use RCA type pin plug cables with the exception described later. Next, set the NTSC/PAL switch (B) to the position corresponding to the standard which your video equipment employs.

CONNECTING SPEAKER SYSTEMS

Connect the SPEAKERS terminals to your speakers with wire of the proper gauge, cut as short as possible. If the connections are faulty, no sound will be heard from the speakers. Make sure that the polarity of the speaker wires is correct, that is, + and – markings are observed. If these wires are reversed, the sound will be unnatural and will lack bass. Do not let the bare speaker wires touch each other or any other metal part as this could damage this unit and/or speakers. Make a connection as figured below with a commercially available scart-plug connector cable.

In this position, low bass signals (below 90 Hz) at the rear surround channels are output from the main speakers (or the SUBWOOFER jacks if the SW or BOTH position is selected on “1D. LFE/BASS OUT”). LARGE: Select this position if your rear effect speakers have a high ability for bass reproduction, or a subwoofer is connected to the rear effect speaker in parallel. In this position, full range signals are output from the rear effect speakers.

Choices: SMALL/LARGE Preset position: LARGE Choices: MAIN/SW/BOTH Preset position: SW SMALL: Select this position if your main speakers do not have a high ability for bass reproduction. However, if your system does not include a subwoofer, do not select this position. In this position, low bass signals (below 90 Hz) at the main channels are output from the SUBWOOFER jacks (if the SW or BOTH position is selected on “1D. LFE/BASS OUT”). LARGE: Select this position if your main speakers have a high ability for bass reproduction. In this position, full range signals present at the main channels are output from the main speakers. English

MAIN: Select this position if your system does not include a subwoofer. In this position, full range signals present at the main channels, signals from the LFE channel and other low bass signals that are selected on 1A to 1C to be distributed from other channels are output from the main speakers. SW/BOTH: Select either the SW or BOTH position if your system includes a subwoofer. In either position, signals at LFE channel and other low bass signals that are selected on 1A to 1C to be distributed from other channels are output from the SUBWOOFER jacks. When the LARGE position is selected on “1C. MAIN SPEAKERS”, in the SW position, no signal is distributed from the main channels to the SUBWOOFER jacks, however in the BOTH position, low bass signals from the main channels are output to both of the main speakers and the SUBWOOFER jacks.

This operation uses an internal test-tone generator for balancing the levels of the main, center and effect speakers.

1. Depress the TEST switch on the remote control so that “TEST

DOLBY SUR.” appears on the display panel to enter test mode. A hiss-like calibration signal should be heard from the left main speaker, center speaker(s), right main speaker, right rear effect speaker and left rear effect speaker in turn (see diagram). Adjust the master VOLUME to a normal listening level.

• The state of test-tone output is shown by the display panel and the monitor screen. (On the monitor screen, it is shown by an image of audio listening room.) This is convenient for adjusting each speaker level. Left main Center Right main LEFT CENTER RIGHT Left rear Right rear LEFT SURROUND RIGHT SURROUND

2. Adjust the center and rear level by using the CENTER and REAR

LEVEL +/– keys on the remote control so that the sound coming from the corresponding speaker seems to be at the same level as that from the main speakers when you are at a normal listening position. The REAR LEVEL +/– keys adjust the right rear level if pressed while the test-tone is output from the right rear effect speaker, and adjust the left rear level if pressed while the test-tone is output from the left rear effect speaker. If the REAR LEVEL + or – key is pressed while the test-tone is output from other than the right or left rear effect speaker, the key adjusts either the right or left rear level that has been adjusted last time.

If there is insufficient volume from the effect speakers, you may decrease the main speaker volume level by setting the MAIN LEVEL switch on the rear panel to “–10 dB”, and adjust the center and rear level again. Volume controls on external power amplifiers may also be adjusted if necessary to achieve proper balance.

Pressing the Parameter + or – key (only when the PARAMETER/SET MENU switch is set to the PARAMETER position) transfers the test-tone from the speaker that is currently outputting the test-tone to the right or left rear effect speaker. Pressing “+” transfers the test-tone to the right rear effect speaker, and “–” to the left rear effect speaker.

Pressing and holding the Parameter Select ▼ or ▲ key (only when the PARAMETER/SET MENU switch is set to the PARAMETER position) fixes the test-tone on the speaker that is currently outputting the test-tone. English MAIN/CENTER/EFFECT SPEAKER LEVEL BALANCE ADJUSTMENT NOTE: If not using a center speaker, be sure to set the CENTER SP mode to the PHNTM (phantom) position. You will then hear the center channel test tone from the left and right main speakers.
