Adjust the horizontal angle of sound beams for each
channel using test tones.
Adjust toward L (left) to move the direction of the output
to the left and adjust toward R (right) to move it to the
right.
Control range: L90° to R90°

Adjust the distance that sound beams travel after being
output and reflected off the wall until they arrive at the
listening position so that all sounds can arrive at the
listening position at the same time.

Adjust the distance from the front of this unit to the focal
point of output for each channel to achieve an expansive

the focus outward (widen the sweet spot) and adjust
(plus) to move the focus toward the normal
position (narrow the sweet spot).
We recommend that you use the initial setting
(-0.5 m or -1.5 ft) for “Center”.
