The speaker layout above shows the standard ITU-R speaker
setting. You can use it to enjoy CINEMA DSP, multi-channel
audio sources and THX.
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.
Surround back speakers (SBR and SBL)
The surround back speakers supplement the surround
speakers and provide for 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 the front speakers.
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.
Presence speakers (PR and PL)
Presence speakers supplement the sound from the front
speakers with extra ambient effects produced by
CINEMA DSP (see page 41). 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 - 1 m (1 - 3 ft) outside the front speakers, facing
slightly inwards, and about 1.8 m (6 ft) above the floor.
■ Di-pole speaker layout
Either di-pole or direct radiating speaker types can be used
for THX surround. If you choose di-pole speakers, please
place the surround and surround back speakers according
to the speaker layout below.
