DC-1 Digital Controller

DC-1Effects

Panorama extracts the natural ambience from recorded music and moves it			Panorama
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.

LOW FREQ WIDTH allows you to apply low-frequency spatial correction to the signal. Positive values of LOW FREQ Width indicate that thedifference signal (L-R) has additional energy below 500Hz, while the sum (L+R) has correspondingly less. Negative settings of LOW FREQ WIDTH can com- pensate for recordings with too much of this property. This control can add needed spaciousness and warmth to classical recordings made with coin- cident or near-coincident 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.
