Speakers to Be Used

This unit has been designed to provide the best sound-
field quality with a 5-speaker system, using left and right
main speakers, left and right rear 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 to ensure even tonal quality.
The main 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, 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.
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
high-performance models that can reproduce sounds over
the full range for the center speaker and the rear speakers.
I 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
the Dolby Digital signal or the DTS signal is played back.
The YAMAHA Active Servo Processing Subwoofer
System is ideal for natural and lively bass reproduction.


Speaker Placement

Refer to the following diagram when you place the
speaker (L)
Center speaker
I Main speakers
Place the left and right main speakers an equal distance
from the ideal listening position. The distance of each
speaker from each side of the video monitor should be the
I Rear speakers
Place these speakers behind your listening position,
facing slightly inwards, nearly 1.8 m (approx. 6 feet)
above the floor.
I 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.
• If the center speaker is not used, the center channel sound will
be heard from the left and right main speakers. In this case,
"1A CENTER SP" on the SET MENU is set to NONE.
I 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 the wall
Please use magnetically shielded speakers. Sometimes
a video monitor may be adversely affected even when
magnetically shielded speakers are used. Separate the
speakers from the monitor if this happens.
