SPEAKER SETUP
Speakers Speaker placement
This unit has been designed to provide the best sound-
field quality with a 5-speaker system, using main left and
right speakers, rear left and right speakers and a 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 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.
Refer to the following diagram when you place the
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, nearly 1.8 m (6 feet) above the
floor.
■ Subwoofer
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 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 and/or center),
change the settings of SPEAKER SET items at the SET MENU
to designate the signals to other terminals you connect speakers
to.

CAUTION
Use magnetically shielded speakers. If this type of
speakers still creates the interference with the monitor,
place the speakers away from the monitor.
