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 a variety of venues such as an actual concert hall, theater, etc. to allow you to accurately recreate one of several actual 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 minimizes 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 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 23.) Front L Main Center Front R Main R

4-Speaker Configuration

The center speaker is not used in this configuration. If the program DOLBY PRO LOGIC or DOLBY PRO LOGIC ENHANCED is selected, the center sound is output from the left and the right main speakers. However, the sound effect of other programs can be the same as that of the 5-speaker configuration. Be sure to set the center channel mode to the PHANTOM position. (For details, refer to page 23.)

OUTPUT terminals (for driving speakers with external amplifiers)
SUBWOOFER OUTPUT terminal
This terminal is for connecting with the input terminal of an amplifier for driving a subwoofer. When the input signals to this unit are in normal 2-channel stereo, this terminal outputs only frequencies below 150 Hz from the main and center channels. When discrete signals are input to this unit and are selected as the input source, this terminal outputs signals from the subwoofer channel.
REAR (SURROUND) OUTPUT terminals
These terminals are for rear channel line output. There is no connection to these terminals when you use the built-in amplifier. However, if you drive rear speakers with an external stereo power amplifier, connect the input terminals of the external amplifier (MAIN IN or AUX terminals of a power amplifier or an integrated amplifier) to these terminals. Note Output level of signals from these terminals are adjusted by the use of VOLUME control on the front panel or VOLUME keys on the remote control transmitter.

CENTER OUTPUT terminal

This terminal is for center channel line output. There is no connection to this terminal when you use the built-in amplifier. However, if you drive a center speaker with an external power amplifier, connect the input terminal of the external amplifier to this terminal.
