Panorama - Lexicon DC-1 - REV 1 Owner's Manual

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.
LF WIDTH allows you to apply low-frequency spatial correction to the
signal. Positive values of LF Width indicate that the difference signal (L-R)
has additional energy below 500Hz, while the sum (L+R) has correspond-
ingly less. Negative settings of LF WIDTH can compensate for recordings
with too much of this property. This control can add needed spaciousness
and warmth to classical recordings made with coincident or near-coinci-
dent microphones.
REAR LEVEL adjusts the loudness of the signals sent to the rear channels.
This control should be set so that the rear is audible without calling
attention to itself. Numerical values and screen graphics are displayed
during adjustment. In systems configured without rear speakers, the
settings affect the level of the side outputs.
