(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.

Dolby Pro Logic Surround + 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. The combination of Dolby Pro Logic Surround and DSP is used on the sound field program PRO LOGIC ENHANCED.

CINEMA DSP

The YAMAHA CINEMA DSP logo indicates these programs are created by the combination of Dolby Pro Logic and YAMAHA DSP technology.

SPEAKER SETUP

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 main speakers, rear speakers and a center speaker. You may omit the center speaker. (Refer to the 4-Speaker Configuration shown below.) The main 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 programs encoded with Dolby Surround. The center speaker needs to be equal in power to the main 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.

SPEAKER CONFIGURATION

5-Speaker Configuration
This configuration is the most effective and recommended one. In this configuration, the center speaker is necessary as well as the rear speakers. If the program DOLBY PRO LOGIC or DOLBY PRO LOGIC ENHANCED is selected, conversations will be output from the center speaker and the ambience will be excellent. Set the center channel mode to the NORMAL or WIDE position. (For details, refer to page 18.)

These are additional 6-channel audio signal input terminals (for left main, right main, center, left rear surround, right rear surround and subwoofer channels) available for inputting signals from your existing amplifier, receiver, sound processor, etc. to this unit. To listen to a sound by reproducing signals input to these terminals from the external amplifier etc., be sure to set the PROCESSOR SELECTOR switch on the front panel to the EXTERNAL position. By doing so, the signals input to these terminals are sent to the corresponding SPEAKERS terminals and OUTPUT terminals of this unit bypassing any circuit in this unit. So, volume, tone, etc. must be controlled on the external amplifier.

PROCESSOR SELECTOR

INTERNAL EXTERNAL

Brief Overview of Digital Sound Field Programs
The following list gives you a brief description of the sound fields produced by each of the DSP programs. Keep in mind that most of these are precise digital recreations of actual acoustic environments. The data for these sound fields was recorded at actual locations using sophisticated sound field measurement equipment. Note The channel level balance between the left and right rear effect speakers may vary depending on the sound field you are listening to. This is due to the fact that most of these sound field recreations are actual acoustic environments.
FEATURE This program is used for playback of sources encoded with Dolby Surround. The application of a sophisticated digital signal processing system reduces crosstalk and directs or steers the sound source more smoothly and precisely, as compared to conventional types. This program is also used 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 movie theater. This effect creates a wide surround sound field, and expands the sound stage with an improved presence image. This program is used for musical based movies, as well as drama and comedy based movies. 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 gives you long delays between direct sounds and effect sounds, and extraordinarily spacious feel of a large stadium. This program recreates the acoustic environment of a lively disco in the heart of a very lively city. The sound is dense and highly concentrated. It is also characterized by a high-energy, immediate sound. This program is ideally suited for rock music. You will experience a very dynamic or lively sound field. In this program, the center will appear to be deep behind the main speakers, creating an expansive large hall ambience. Orchestra and opera music are suited for this sound field.
