BEAM TRAVEL LENGTH (Beam travel length)
A certain amount of delay must be applied to the sound
from each channel so that all sound will 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 adjust the delay applied to the respective
channel.
The lines in the illustration below indicate the distance.
Choices: 0.3 m (1.0 ft) to 24.0 m (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.

We recommend that you use the setting optimized by the AUTO
SETUP (see page 27). Set this menu only when you changed the
HORIZONTAL ANGLE (see page 60).
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.
Choices: –1.0 m (–3.5 ft) to +13.0 m (+43.5 ft)
Adjust towards – (minus) to move the focus outward and
adjust t (plus) to move the focus towards the
normal position.
•
Front L
adjusts the focal length for the front left sound
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 (–1.5 ft)
•
Surround L
adjusts the focal length for the surround
left sound beams.
•
Surround R
