BEAM settings

When "AUTO SETUP" in the "IntelliBeam" menu (☞p. 24) is
used, recommended beam settings are automatically applied by
this unit. "HORIZONTAL ANGLE", "BEAM TRAVEL
LENGTH", "FOCAL LENGTH" (except "Center"), and
"IMAGE LOCATION" settings, however, can later be
fine-tuned.
Surround sound channel output can also be modified from the
"BEAM" menu.

HORIZONTAL ANGLE

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.

BEAM TRAVEL LENGTH

Specify the distance that sound beams travel for each channel.
The distance starts at this unit, ends at the listening position, and
includes refraction off a wall. The audio delay is adjusted and
sound from each channel arrives at the listening position
simultaneously.

FOCAL LENGTH

Expand the optimal listening area (sweet spot).
The illustration below shows how output from all channels is
once concentrated in a focal point and then expanded from that
point. Apply negative (-) values to broaden the sweet spot, or
positive (+) values to narrow the sweet spot.
