PANORAMA
Designed for playback of stereo and matrix-encoded sources.
Uses proprietary algorithms to move the stereo image out-
ward from the front speakers, producing a wider stereo field
with greater depth.
Depends on proper location of the listening position and
front speakers. When the front speakers are positioned close
to either side of the display device, the effect is produced over
a wider area than when the front speakers are positioned at a
large angle from the display device.
See “Listening Mode Menu Option & Parameter Descriptions” on page 5-29 for detailed
descriptions

PANORAMA CALIBRATION
The PANORAMA listening mode must be calibrated to take
full advantage of its effects.
For best results, it is recommended that you center the pri-
mary listening position between the front left and right speak-
ers as shown in the illustration centered at the top of page 5-
14. Otherwise, the PANORAMA listening mode will be cali-
brated with various results.
See “Listening Mode Menu Option & Parameter Descriptions” on page 5-29 for detailed
descriptions
.
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. Then, enter these dis-
tances on the SPEAKER DISTANCES menu.
3. Sit in the primary listening position. If the primary listening posi-
tion is not centered between the front left and right speakers, set
the LISTENER POS parameter to compensate for the difference.
4. Set the SOURCE parameter to RIGHT.
5. Begin playback of the calibration source. It is recommended you
use a familiar stereo.
