■ Speaker placement
Refer to the following diagram when you place the
speakers.
Main speakers
Place the main left and right speakers an equal distance
from the ideal listening position. The distance between
each speaker and each side of the video monitor should
also be the same.
Center speaker
Align the front face of the center speaker with the front
face of your video monitor. Place the speaker as close to
the monitor as possible (such as directly over or under the
monitor) and centrally between the main speakers.
Rear speakers
Place these speakers behind your listening position,
facing slightly inwards, about 1.8 m (6 feet) above the
floor.
Rear center speaker
Place the rear center speaker in the center between the
rear left and right speakers at the same height from the
floor as the rear speakers.
Subwoofer
The position of the subwoofer is not so critical, because
low bass sounds are not highly directional. However, it is
better to place the subwoofer near the main speakers.
Turn it slightly toward the center of the room to reduce
wall reflections.
Note
• If you do not use any of effect speakers (rear, center and/or
rear center), change the settings of “SOUND 1 SPEAKER
SET” items at the set menu to direct signals to other terminals
you have connected speakers to.
CAUTION
Use magnetically shielded speakers. If these speakers
still create interference with the monitor, place the
speakers away from the monitor.
Connecting the speakers
■ Speakers
This unit has been designed to provide the best sound-
field quality with a 6-speaker system, using main left and
right speakers, rear left and right speakers, a center
speaker, and a rear center speaker. If you use different
brands of speakers (with different tonal qualities) in your
system, the tone of a moving human voice and other types
of sound may not shift smoothly. We recommend that you
use speakers from the same manufacturer or speakers
with the same tonal quality.
The main speakers are used for the main source sound
plus effect sounds. They will probably be the speakers
from your present stereo system. The rear speakers are
used for effect and surround sounds. The center speaker is
for the center sounds (dialog, vocals, etc.). The rear center
speaker supplements the rear (left and right) speakers and
provides for more realistic front-to-back transitions.
The main speakers should be high-performance models
and have enough power-handling capacity to accept the
maximum output of your audio system. The other
speakers do not have to be equal to the main speakers. For
precise sound localization, however, it is ideal to use the
models of equivalent performance with the main
speakers.
Use of a subwoofer expands your sound field
It is also possible to further expand your system with the
addition of a subwoofer. The use of a subwoofer is
effective not only for reinforcing bass frequencies from
any or all channels, but also for reproducing the LFE
(low-frequency effect) channel with high fidelity when
playing back Dolby Digital or DTS signals. The
YAMAHA Active Servo Processing Subwoofer System is
ideal for natural and lively bass reproduction.
