MANUAL SETUP
HORIZONTAL ANGLE (Horizontal angle)
Use to adjust the horizontal angle of sound beams for each
channel. By adjusting the horizontal angle of the sound
beams, you can optimize the sound beam paths. A test
tone is automatically output.
Choices: L90° to R90°
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.

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.
Choices: 0.3 m to 24.0 m (1.0 ft to 80.0 ft)
• Front L adjusts the distance the front left channel
sound beams travel.
• Front R adjusts the distance the front right channel
sound beams travel.
• Center adjusts the distance the center channel sound
beams travel.
• Surround L adjusts the distance the surround left
channel sound beams travel.
• Surround R adjusts the distance the surround right
channel sound beams travel.
