MANUAL SETUP
FOCAL LENGTH (Focal length)
Use to set the distance from the front of this unit to the
focal point of output for each channel and adjust an
expansive feeling of each channel.
The focal points except the center channel should be set
near the reflection points on the walls. The shorter the
distance, more the expansion.
Front left channel Center channel
Choices: -1.0 m to +13.0 m
Adjust towards - (minus) to move the focus outward and
adjust towards + (plus) to move the focus towards the
normal position.

beams.
• Front R adjusts the focal length for the front right
sound beams.
• Center adjusts the focal length for the center sound
beams. Initial setting: -0.5 m

center channel.
TREBLE GAIN (Treble gain)
Use to adjust the high frequency output level of each
channel.
If the reflection point of the front left and right or surround left
and right sound beams is a curtain or other acoustically absorbent
surface, you can achieve more effective surround sound by
increasing the treble level for those sound beams.
Initial setting: 0 dB
