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.

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.
Dolby Pro Logic Surround
The Dolby Pro Logic Surround Decoder program lets you experience the dramatic realism and impact of 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 channel separation for a much higher degree of realism than the “passive” Dolby Surround circuits found in today’s typical home audio/video equipment. Dolby Pro Logic Surround provides a true center channel, so that 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 the action on the screen while experiencing good stereo imaging.

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.
In addition, this unit features a built-in automatic input balance control. This always assures you the best performance without manual adjustment.
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.
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 No. 5 through No. 14, and No. 16.
The YAMAHA “CINEMA DSP” logo indicates these programs created by the combination of Dolby Pro Logic and YAMAHA DSP technology.
VIDEO SUPERIMPOSE
If you connect your video cassette recorder, video disc player, video monitor, etc. to this unit, you can take advantage of this unit’s capability to display program titles, parameter data and information about other various settings and adjustments on your video monitor’s screen. This information will be superimposed over the video image.

Setting Up Your Speaker System
This unit has been designed to provide the best sound field |
5 Speaker System |
4 Speaker System |
quality with a full five-speaker system setup, using one extra pairs of |
|
|
effect speakers to generate the sound field plus one center speaker |
|
|
for dialog, when using Dolby Pro Logic Surround decoding. We |
|
|
therefore recommend that you use a five-speaker 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 five speaker system later. |
|
|
Use of the Center Dialog Speaker Is Recommended
With digital sound field programs No. 5 through No. 16, by using either the Directional Enhancement circuit or the Dolby Pro Logic decoder, decoded signals will be output from the center channel. Therefore, if you want to upgrade the Audio/Video home theater system, it is recommended to use the center speaker unit.
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.
It is also possible to further expand your system with the addition of a subwoofer and amplifier. You may wish to choose the convenience of a Yamaha Active Servo Processing Subwoofer System, which has its own built-in power amp.
This is the recommended speaker system, providing the best sound effects.
With sound field programs No. 1 through No. 4, using effect speakers reproduces the effective sound field. With the sound field programs No. 5 through No. 16, the center speaker provides precise center localization.
Center Mode—Set to NRML or WD. (See page 22.)
Simple system without center speaker.
With sound field programs No. 1 through No. 4, a sound effect matching that of a 5-speaker system can be obtained. With sound field programs No. 5 through No. 16, center sound is output from the left and right main speakers.
Center Mode—Set to PHNTM. (See page 22.)

Speakers and Speaker Placement
Your full five-speaker system will require two speaker pairs: the MAIN SPEAKERS (your normal stereo speakers) and the REAR EFFECT SPEAKERS, plus the CENTER SPEAKER. You may also be using a subwoofer.
You will probably use your present stereo speakers as the MAIN SPEAKER pair. The rear effect do not need to be equal with the MAIN SPEAKERS, although the center speaker should be as close as possible. They should have enough power handling capacity to accept the maximum output of the DSP system.
Place the MAIN SPEAKERS in the normal position.
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.) |
Main speaker |
Rear effect speaker Center 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.
NOTE: The Yamaha NS-C110 speaker, available in some countries, is an ideal choice for the center speaker.

GENERAL INSTRUCTIONS FOR CONNECTIONS
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 other plugs for the “L” jacks.
With speaker connections you must also be sure that the polarity is correct. For each amplifier and each channel, connect the plus (+) terminal of the amplifier to the plus terminal of the speaker, and connect the minus (–) terminal of the amplifier to the minus terminal of the speaker. To keep track of polarity, use a speaker cable that has one of the two wires marked by a stripe or a different color.
