➤ When surround effect is not enough
En

The unit achieves its surround sound effects by projecting sound beams which reflect 
off walls. The sound beams are not reflected toward to the listening position caused by 
furniture, etc., in the path of sound beams, or the room shape. In this case, the sound 
may become unbalanced.
If the sound beams are not reflected toward to the listening position (figure 2), you can
adjust for this by installing the optional sound reflection board YRB-100.
• YRB-100 may not be available in some countries or regions.

Decide the position of the sound reflection board.
Install the sound reflection board as shown in the picture.
• Always hold the pole when moving the sound reflection board.
• Use “CHANNEL LEVEL” in the setup menu (p. 56) to determine the precise direction from which 
sounds are difficult to hear.
When surround effect is not enough
Figure 1. Ideal condition
Figure 2. Surround right beam is not 
being reflected because there 
is no wall.
Surround right is quieter than surround 
(left), or surround right is in front of its 
proper location.
Figure 3. With a sound reflection board 
installed
The sound beam for surround right is 
reflected correctly, and correct surround 
sound effect is achieved.
