Yamaha RX-SL80 - Manual (Page 12)

SPEAKER SETUP
8
You can enjoy this unit with the following speaker setup to
obtain the best surround sound.
y
The speaker layout above shows the standard ITU-R* speaker
setting. ITU-R recommends that the front left and right speakers
be placed at 30° from the central listening position, and that the
surround left and right speakers be placed at between 60° and 80°
from the central listening position.
* ITU-R: for more information (see page 54).
Front speakers (FR and FL)
The front speakers are used for the main source sound plus
effect sounds. Place these speakers 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 (C)
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. Align the front
face of the center speaker with the front face of your video
monitor. Place the speaker centrally between the front
speakers and as close to the monitor as possible, such as
directly over or under it.
Surround speakers (SR and SL)
The surround speakers are used for effect and surround
sounds. Place these speakers behind your listening
position, facing slightly inwards, about 1.8 m (6 ft) above
the floor.
Subwoofer
The use of a subwoofer, 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 high fidelity reproduction of the LFE (low-
frequency effect) channel included in Dolby Digital and
DTS software. 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.
