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.
