The speaker layout below shows the standard ITU-R
*
speaker setting. You can use it to enjoy CINEMA DSP and
multi-channel audio sources.
*
ITU-R is the radio communication sector of the ITU
(International Telecommunication Union).
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 provides 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 71). These effects include
sounds that filmmakers intent 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 – 1 m (1 – 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 hi-fi
stereo 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.
