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 speaker (SB)
The surround back speaker supplements the surround 
speakers and provides more realistic front-to-back 
transitions. Place this speaker directly behind the listening 
position and at the same height as the surround speakers.

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.
