Placing speakers
The speaker layout below shows the speaker setting we recommend. You can use it to enjoy the CINEMA DSP and
multi-channel audio sources.
■ 7.1 -channel speaker layout
7.1-channel speaker layout is highly recommended for playback the sound of high definition audio formats (Dolby
TrueHD, DTS-HD Master Audio, etc.) as well as the conventional audio sources with sound field programs. See page 14
for connection information.
We recommend that you also add the presence speakers for the effect sounds of the CINEMA DSP sound field program. See page 13 for
details.

Front ieft and right speakers
The front speakers are used for the main source sound plus effect sounds. Place these speakers at an equal distance from the
ideal listening position. The distance of each speaker from each side of the video monitor should be the same.
Center speaker
The center speaker is for the center channel sounds (dialog, vocals, etc.). If for some reason it is not practical to use a
center speaker, you can do without it. Best results, however, are obtained with the full system.
Surround left and right speakers
The surround speakers are used for effect and surround sounds.
Surround back ieft and right speakers
The surround back speakers supplement the surround speakers and provide more realistic front-to-back transitions.
Subwoofer(s)
The use of a subwoofer with a built-in amplifier, such as the Yamaha Active Servo Processing Subwoofer System, is
effective not only for reinforcing bass frequencies from any or all channels, but also for reproducing the high fidelity
sound of the LEE (low-frequency effect) channel included in Dolby Digital and DTS sources. You can connect one or
two subwoofer(s) to this unit. When you use two subwoofers, you can enjoy deeper bass sound. The position of the
subwoofer is not so critical, because low bass sounds are not highly directional. But it is better to place the subwoofer
near the front speakers. Turn it slightly toward the center of the room to reduce wall reflections.
\i/
When you use two subwoofers, select the same type of the subwoofer as another and set these subwoofers as same sound characteristics.
Place each subwoofer at the same distance from the listening position. The signal output at the SUBWOOFER PRE OUT 2 is the same
as the one output at the SUBWOOFER PRE OUT 1 jack.
