PREPARATIONPREPARATION
The speaker layout below shows the speaker setting we
recommend. You can use it to enjoy CINEMA DSP and
multi-channel audio sources.
Front left and right speakers (FL and FR)
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 (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. Place the
center speaker centrally between the front speakers and as
close to the monitor as possible, such as directly over or
under it.
Surround left and right speakers (SL and SR)
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.
Surround back left and right speakers
(SBL and SBR)
The surround back speakers supplement the surround
speakers and provide more realistic front-to-back
transitions. Place these speakers directly behind the
listening position and at the same height as the surround
speakers. They should be positioned at least 30 cm (12 in)
apart. Ideally, they should be positioned at the same width
as that of the front speakers.
Presence left and right speakers (PL and PR)
The presence speakers supplement the sound from the front
speakers with extra ambient effects produced by CINEMA
DSP (see page 153). These effects include sounds that
filmmakers intend to locate a little farther back behind the
screen in order to create more theater-like ambience. Place
these speakers at the front of the room about 0.5 to 1 m (1
to 3 ft) outside the front speakers, facing slightly inward,
and about 1.8 m (6 ft) above the floor.
Subwoofer (SW)
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 high
fidelity sound reproduction of the LFE (low-frequency
effect) channel included in Dolby Digital and DTS
sources. 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.
