ITU

 

(International Telecommunication Union).

 

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.

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.

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.

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

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.
