Digital Sound Field Processing
What is it that makes live music so good? Todays advanced sound reproduction technology lets you get extremely close to the sound of a live performance, but chances are youll 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 youll feel all the sound of a live concert. Furthermore, our technicians, armed with sophisticated measuring equipment, have even made it possible to capture the acoustics of actual music venues to allow you to accurately recreate live performance environments in your own home.
Dolby Pro Logic Surround
The Dolby Pro Logic Surround Decoder program lets you experience the dramatic realism and impact of a Dolby Surround movie theater sound in your own home. Dolby Pro Logic gets its name from its professional-grade steering logic circuitry, which provides greater effective front and rear channel separation for a much higher degree of realism than the passive Dolby Surround circuits found in less sophisticated home audio/video equipment. Dolby Pro Logic Surround provides a true center channel, so there are four independent channels, unlike passive Dolby Surround which has in effect only three channels: left, right, and rear. This center channel allows listeners seated in even less-than-ideal positions to hear the dialog originating from action on the screen while getting a stereo effect as well. In addition, this unit features a built-in automatic input balance control. This circuit always presents you the best surround conditions without performing manual adjustments.
Dolby Pro Logic Surround + DSP
You can also enjoy a combination of Dolby Pro Logic Surround and DSP in the sound field program PRO LOGIC ENHANCED. It recreates the surround effect of a movie theater, effectively duplicating its multiple surround loudspeaker system, completely surrounding the listener with the sounds of the action taking place on the screen.
SPEAKERS TO BE USED
This unit is designed to provide the best sound-field quality with a 5 speaker configuration. The most effective speakers to use with this unit are front speakers, rear speakers and a center speaker. You may omit the center speaker. (Refer to the 4-Speaker Configuration shown below.) The front speakers are used for the main source sound plus the effect sounds. They will probably be the speakers from your present stereo system. The rear speakers are used for the effect and surround sounds, and the center speaker is for the center sounds (dialog etc.) within the Dolby Surround encoded programs. The center speaker needs to be equal in power to the front speakers, although the rear speakers should not be equal. However, all the speakers should have high enough power handling to accept the maximum output of this unit.
This configuration is the most effective and recommended one. In this configuration, the center speaker is necessary as well as the rear speakers. If a Dolby Surround program is selected, conversations will be output from the center speaker and the ambience will be excellent. q Set the center channel mode to the NORMAL or WIDE position. (For details, refer to page 12.)
The center speaker is not used in this configuration. If a Dolby Surround program is selected, the center sound is output from the left and the right front speakers. However, the sound effect of other programs can be the same as that of the 5-speaker configuration. q Be sure to set the center channel mode to the PHANTOM position. (For details, refer to page 12.)
The program DOLBY 3 STEREO is useless in this configuration.
Surround sound Rear L Rear R
As this unit is equipped with a monaural amplifier for the rear channel, you may use one rear speaker only instead of using two rear speakers. However, the use of two rear speakers is recommended when there are more than one listener in the listening room. When using one rear speaker, place it right behind your listening position.
The recommended speaker configuration, the 5-speaker configuration, will require two speaker pairs: front speakers (your normal stereo speakers), and rear speakers, plus a center speaker. When you place these speakers, refer to the following.
Front R Center Front L TV set Rear R
In normal position. (The position of your present stereo speaker system.) Rear: Behind your listening position, facing slightly inward. Nearly six feet (approx. 1.8 m) up from the floor. Center: Precisely between the front speakers. (To avoid interference with TV sets, use a magnetically shielded speaker.)
Before attempting to make any connections to or from this unit, be sure to first switch OFF the power to this unit and to any other components to which connections are being made. When making connections between this unit and other components, be sure all connections are made correctly, that is to say L (left) to L, R (right) to R, + to + and to. Also, refer to the owners manual for each component to be connected to this unit.

Description of Each Sound Field Program
The following list gives brief descriptions of the sound fields produced by each of the DSP programs. Keep in mind that some of these are precise digital recreations of actual acoustic environments. The data for them was recorded at actual places using sophisticated sound field measurement equipment. Note The channel level balance between the left rear effect speaker and the right rear effect speaker may vary depending on the sound field you are listening to. This is due to the fact that some of these sound field recreations are actual acoustic environments. PROGRAM FEATURE This program is effective for playback of sources encoded with Dolby Surround. Compared to the conventional 3-channel surround-sound system, the true center channel is added, thus even further expanding the width of the surround-sound effect. This program is effective for playback of sources encoded with Dolby Surround. Enhancing the Normal Dolby Pro Logic, the DSP technology simulates the multi-surround speaker systems of a 35 mm film theater, thus widening the surrounded-sound field with greater presence. This program is effective for music videos and gives excellent depth and clarity for vocals. For opera, the orchestra and stage are ideally recreated, letting you feel as if you were in an actual concert hall. This program is designed specifically to enhance mono source programs. Compared to a strictly mono setting, the sound image created in this mode is wider and slightly forward of the speaker pair, lending an immediacy to the overall sound. It is particularly effective when used with old mono movies, news broadcasts and dialog. This program is effective not only for playback of sources encoded with Dolby Surround, but also for sources not encoded with Dolby Surround or TV programs with 2-channel stereo sound. With this program, 2-channel stereo sound is converted into 3-channels (left front, center and right front), so the dialogs are emphasized on the center position by the use of the center speaker. As no sound is output from the rear speakers, this program is also effective in a simple Audio/Video system without rear speakers. This program is suitable for rock music. A big, powerful sound is reproduced lively and dynamically. In this program, the center seems deep behind the front speaker pair, creating an expansive, large hall ambience.

Description of Dolby Pro Logic Surround
DOLBY PRO LOGIC SURROUND: This unit employs the Dolby Pro Logic Surround system. This system is similar to professional Dolby Stereo decoders used in movie theaters. By employing a four-channel system, the Dolby Pro Logic Surround system divides the input signals into four levels: the left and right main channels, the center channel (to characterize dialog), and the rear surround-sound channels (to characterize sound effects, background noise and other ambient noise). Dolby Surround is encoded on the sound track of commercially available video cassettes and video discs as well. When you play a source encoded with Dolby Surround on your home video system, the Dolby Pro Logic Surround system in this unit decodes the signal and feeds the surround-sound effects. The Dolby Pro Logic Surround mode may not be always effective on video sources not encoded with Dolby Surround.
Manufactured under license from Dolby Laboratories Licensing Corporation. Additionally licensed under Canadian patent number 1,037,877. Dolby, Pro Logic, and the double-D symbol are trademarks of Dolby Laboratories Licensing Corporation.
To play a source with the digital sound field processor
Follow steps shown in BASIC OPERATIONS on page 14.
Notes If you prefer to cancel the DSP, press the EFFECT switch. The sound will be the normal 2-channel stereo without surround sound effect. When this units Dolby Pro Logic Surround system is used, if the main-source sound is considerably altered by overadjustment of the BASS or TREBLE controls, the relationship between the center and rear channels may produce an unnatural effect.
Select the desired program that is suitable for the source.
When CONCERT VIDEO, MONO MOVIE, ROCK CONCERT or CONCERT HALL is selected, no sound is heard from the center speaker. When a monaural sound source is played with DOLBY PRO LOGIC or DOLBY PRO LOGIC ENHANCED, no sound is heard from the front speakers and the rear speakers. Sound is heard only from the center speaker. However, if the center channel mode is in PHANTOM, the front speakers output the sound of the center channel.
The selected program name is shown on the display.
When ROCK or HALL is selected, no sound is heard from the center speaker. When a monaural sound source is played with DOLBY PRO LOGIC or DOLBY 3 STEREO, no sound is heard from the front speakers and the rear speakers. Sound is heard only from the center speaker. For DOLBY PRO LOGIC only, however, if the center channel mode is in PHANTOM, the front speakers output the sound of the center channel.
Whenever the SLEEP key is pressed, the SLEEP time will change as follows.
The SLEEP timer is off (OFF). (The state before the SLEEP key is pressed.) After a while, the display returns to the indication before the SLEEP timer is set, and the SLEEP indicator is illuminated.
The unit will be turned off automatically at the selected SLEEP time.

NOTES ABOUT THE REMOTE CONTROL TRANSMITTER
Battery installation Remote control transmitter operation range
Remote control sensor
Within approximately 6 m (19.7 feet)
If you find that the remote control transmitter must be used closer to the main unit, the batteries are weak. Replace both batteries with new ones. Notes q Use only AA, R6, UM-3 batteries for replacement. q Be sure the polarities are correct. (See the illustration inside the battery compartment.) q Remove the batteries if the remote control transmitter will not be used for an extended period of time. q If batteries leak, dispose of them immediately. Avoid touching the leaked material or letting it come in contact with clothing, etc. Clean the battery compartment thoroughly before installing new batteries.
Notes q There should be no large obstacles between the remote control transmitter and the main unit. q 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 not to work correctly. In this case, reposition the main unit to avoid direct lighting.
If the unit fails to operate normally, check the following points to determine whether the fault can be corrected by the simple measures suggested. If it cannot be corrected, or if the fault is not listed in the SYMPTOM column, disconnect the power cord and contact your authorized YAMAHA dealer or service center for help.
