PANORAMA
• Designed for playback of stereo and matrix-encoded sources.
• Uses proprietary 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 primary 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.

CALIBRATION
• Selecting the PANORAMA listening
mode menu CALIBRATION option
opens the PANORAMA CALIBRATION
menu shown at the right, which can
be used to calibrate the PANORAMA
listening mode. This listening mode
must be calibrated to take full
advantage of its effects.
• For best results, it is recommended to center the primary
listening position between the front left and right speakers as
shown in illustration 5-B at the top of the next page (center).
Otherwise, the PANORAMA listening mode will be calibrated
with various results.
• An external calibration source is required to calibrate the
PANORAMA listening mode. It is recommended to select a
familiar stereo source.
