DC-1 Effects

SURROUND 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 dis-
played during adjustment. The settings also affect the level of the side
outputs.
BASS CONTENT allows you to modify the bass content for Mono, Stereo or
Binaural recordings. The BINAURAL setting turns the rear level parameter
off and activates special low-frequency compensation. This feature is
offered specifically for true binaural recordings made with a dummy head.
LOW FREQ WIDTH allows you to apply low-frequency spatial correction
to the signal. Positive values of LOW FREQ Width indicate that the difference
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 coinci-
dent or near-coincident microphones.
SUBWOOFER LVL boosts or cuts the subwoofer output level. Although the
normal subwoofer level is set during the calibration procedure, with some
recordings it may be desirable to increase or decrease this deep bass level.
EFFECT LEVEL changes the apparent width of the front soundstage. 0 =
ordinary stereo, 62 provides the widest image.
