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
primary
listening position between the front left and right speakers.
Otherwise, the PANORAMA listening mode will be calibrated
with various results.
Option/ Default Possible
Parameter Setting Settings
SOURCE LEFT & RIGHT RIGHT, LEFT & RIGHT, LEFT
SPEAKER ANGLE 30deg 10deg to 90deg
LISTENER POS +0 –127 to +127
See “Listening Mode Menu Option & Parameter Descriptions” on page 5-29 for
detailed descriptions of these options and parameters.
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
distances on the SPEAKER DISTANCES menu.
3. Sit in the primary listening position. If the primary listening
position 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
that you use a familiar stereo source.
PANORAMA
• Designed for playback of stereo and matrix-encoded sources.
• Uses proprietary Lexicon algorithms to move the stereo
image outward 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.
