PANORAMA (continued)
To calibrate the PANORAMA listening mode:
1. Remove all obstructions between the speakers and the primary
listening position.
2. Make sure the distances between the speakers and the primary
listening position are properly measured. To do this, perform
the following procedure:
Measure the distance between the primary listening position
and the front baffle of each speaker. Then, set the
corresponding SPEAKER DISTANCES menu parameters to the
closest available value.
3. Sit in the primary listening position. If the primary listening
position is not centered between the front left and right
speakers as shown in the Center illustration (above), set the
PANORAMA CALIBRATION LISTENER POS parameter to
compensate for the difference using the remote control or
arrow button. Each increment within the –127 to +127
parameter range represents about one-third of an inch.
Adjusting the offset more to the left will make the value more
negative; more to the right will make the value more positive.
The Left illustration shows the left of center position. The Right
illustration shows the right of center position.
4. Set the SOURCE parameter to RIGHT.
5. Begin playback of the external calibration source.
6. When playback of the external calibration source is in progress,
set the SPEAKER ANGLE parameter so the sound is not heard in
the right ear.
7. To confirm the LISTENER POS and SPEAKER ANGLE parameter
settings, set the SOURCE parameter to LEFT & RIGHT. If the
PANORAMA listening mode is properly calibrated, the sound
should be perceived to come from all around the primary
listening position. If not, go back to Step 1 and repeat the
calibration procudure.
