Panorama - Lexicon DC-1 - ADDENDUM Owner's Manual Addendum

DC-1 Digital Controller
Panorama extracts the natural ambience from recorded music and moves it
outward from the speakers, producing greater width and depth of image
and a feeling of enhanced spaciousness. This mode adds no additional
sound but expands the existing stereo image. Panorama also works with
Dolby Stereo movies, bringing the surround track outward into the room.
The location of the front speakers and the listening position are crucial to
Panorama's effectiveness and for best results your system and the DC-1
together should be set up and calibrated according to the procedure in
Chapter 2. The strength of the Panorama effect drops off as you move away
from the prime listening position, especially to the sides. Video systems
with the main loudspeakers spaced closely on either side of a TV screen will
produce a usable effect over a somewhat wider area than set-ups with a
large included angle between the speakers.

INPUT BALANCE allows you to compensate for the occasional source with
audible channel imbalance. When selected, screen graphics indicate the
relative left/right position.
CENTER LEVEL adjusts the output level from the center speaker.
REAR ROLLOFF sets the frequency above which the rear-channel sound is
attenuated. The appropriate setting will vary with the program material. It
should be set high enough to give presence and airiness to the rear sound
without placing distracting instrumental overtones or other sounds behind
you. The settings also affect the side outputs.
REAR DELAY adjusts the amount of time between the appearance of a
signal in the front channels and its emergence from the rear. Generally, the
correct delay is about 16 milliseconds, but the setting depends on speaker
set-up and source material. In general, the delay should be low enough so
that the rear sound does not become identifiable as a distinct source. The
settings also affect the side outputs.
