Panorama is also used as an element in the ambience and reverb simulation
effects, where it can synthesize side loudspeakers which are not present in
the installation. In these effects, the stereo inputs to the processor are fed
directly to the front loudspeakers, with the digital outputs mixed in accord-
ing to the setting of the processor's Effect Level control. The Ambience or
Reverb side outputs are sent through Panorama before being mixed into the
front loudspeakers, so the added sound spreads beyond them and does not
interfere with the original material. When side speakers are present, the
Panorama Effect parameter is automatically turned down and no mixing
occurs into the front speakers.

Speaker alignment is important. A 6"
difference in the distance to the rear wall
can greatly change the effective area,
unless compensated for by the LIS-
TENER POSITION parameter.
