 En

This unit supports up to 7.1-channel surround. We recommend the following speaker layout in order to obtain the 
optimum surround effect.

7.1-channel speaker layout

6.1-channel speaker layout

5.1-channel speaker layout

■

Front left and right speakers (FL and FR)

The front speakers are used for the front channel sounds 
(stereo sound) and effect sounds. Place these speakers at 
an equal distance from the ideal listening position. When 
using a screen, the appropriate top positions of the 
speakers are about 1/4 of the screen from the bottom.

■

Center speaker (C)

The center speaker is for the center channel sounds 
(dialog, vocals, etc.). Place it halfway between the left and 
right speakers. When using a TV, place the speaker just 
above or just under the center of the TV with the front 
surfaces of the TV and the speaker aligned. When using a 
screen, place it just under the center of the screen.

■

Surround left and right speakers (SL and SR)

The surround speakers are used for effect and surround 
sounds.
Place them at the rear left and rear right facing the 
listening position. 
To obtain a natural sound flow in the 5.1-channel speaker 
layout, place them slightly further back than in the 7.1-
channel speaker layout.

■

Surround back left and right speakers (SBL 
and SBR) / Surround back speaker (SB)

The surround back left and right speakers are used for rear 
effect sounds. Place them at the rear of the room facing the 
listening position at least 30 cm away from each other, 
ideally at the same distance as that between the front left 
and right speakers. 
In the 6.1-channel speaker layout, surround back left and 
right channel sound signals are mixed down and output 
from the single surround back speaker. 
In the 5.1-channel speaker layout, surround back left and 
right channel sound signals are output from the surround 
left and right speakers. 

■

Subwoofer (SW)

The subwoofer speaker is used for bass sounds and low-
frequency effect (LFE) sounds included in Dolby Digital 
and DTS signals. Use a subwoofer with a built-in 
amplifier, such as the Yamaha Active Servo Processing 
Subwoofer System. Place it exterior to the front left and 
right speakers facing slightly inward to reduce reflections 
from a wall.
