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.

• Use “CHANNEL LEVEL” in the setup menu (p. 56) to determine the precise direction from which
sounds are difficult to hear.
