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 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 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 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 49). 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
outside the front speakers, facing slightly inwards, and
about 1.8 m above the floor.
