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.
How to install YRB-100
The unit outputs sound beams according to the “Position” settings (p. 18) as shown in
the following illustrations.
Install the YRB-100 in the path of the sound beam.
shows the recommended install position.
• After installing the sound reflection board, refer to the YRB-100 owner’s manual to
adjust the height and angle. Playing test-tones from “Channel Level” in the setup
menu is recommended when adjusting the board (p. 49).
• By installing the board close to your listening position, you can achieve clear surround
sound positioning.
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.
Note
• This unit does not have the function to automatically adjust sound beam angles. It is not necessary to
adjust the sound beam angles, although the procedure is described in the owner’s manual.
