PROFILE OF THIS UNIT

CINEMA DSP

You are the proud owner of a Yamaha stereo receiver –an extremely sophisticated audio component. The Digital Sound Field Processor (DSP) built into this unit takes full advantage of Yamaha’s undisputed leadership in the field of digital audio processing to bring you a whole new world of listening experiences. Follow the instructions in this manual carefully when setting up your system, and this unit will sonically transform your room into a totally new listening environment – movie theater, concert hall, and so on. In addition, you get incredible realism from Dolby Surround-encoded video sources using the built-in Dolby Pro Logic Surround Decoder. Please read this operation manual carefully and store it in a safe place for later reference.

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.

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.

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 live performance environments in your own home.

This Dolby Pro Logic Surround Decoder employs a digital signal processing system. This system increases sound stability at each channel and minimizes crosstalk between channels compared to conventional analog Dolby signal processing. 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

Additionally you can enjoy sound environment created by the combination of Dolby Pro Logic and YAMAHA DSP. Precise sound movement and orientation by the Dolby Pro Logic technology is added to sound fields which are precisely recreated on the basis of actual acoustic environments by the DSP technology, so it is suitable for any Audio/Video source with video image. This combination is used on sound field programs “DOLBY PRO LOGIC ENHANCED”, “70 mm MOVIE THEATER”, “TV THEATER” and “SPORTS”.

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

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.

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 digital sound field program DOLBY

PRO LOGIC, DOLBY PRO LOGIC ENHANCED, 70 mm MOVIE THEATER, TV THEATER or SPORTS 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 14.)

4-Speaker Configuration

The center speaker is not used in this configuration. If the digital sound field program DOLBY PRO LOGIC, DOLBY PRO

LOGIC ENHANCED, 70 mm MOVIE THEATER, TV THEATER or SPORTS 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 5speaker configuration.

●

Be sure to set the center channel mode to the “PHANTOM” position. (For details, refer to page 14.)

SPEAKER PLACEMENT

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: 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.)
