MANUAL SETUP
BEAM TRAVEL LENGTH (Beam
travel length)
A certain amount of delay must be applied to the sound
from each channel so that all sounds can arrive at the
listening position at the same time. This menu sets the
distance that sound beams travel after being output and
reflected off the wall until they arrive at the listening
position and adjusts the delay applied to the respective
channel.
The lines in the illustration below indicate the distance.
FOCAL LENGTH
(Focal length)
Use to set the distance from the front of this unit to the
focal point of output for each channel to achieve an
expansive feeling for each channel.
The focal points except for the center channel should be
set near the reflection points on the walls. The shorter the
distance, the larger the expansion.
