DC-1 Effects

CENTER LEVEL attenuates the level of the center channel and can turn it
off completely.
FRONT STEERING (available only in Music Logic) allows you to adjust the
amount of steering in the front channels. When this control is set to FULL,
the effect is identical to Dolby Pro Logic. At the 1/2 and 1/4 settings,
steering is reduced to accommodate the wide range of television program-
ming. Selecting OFF steers the signal to both the left and right channels.
SIDE LEVEL controls the volume level of the side speakers. Although we
have sleected a default value, the correct setting will vary with each
recording, the room, and your personal taste.
SIDE ROLLOFF provides a high frequency cutoff for the side speakers. The
optimal setting for this control will vary widely with the source material.
REAR ROLLOFF sets the cutoff frequency of a low pass filter in the rear-
channel. Frequencies above this setting are attenuated. This control should
be set high enough to give presence and airiness to the rear sound without
placing distracting instrumental overtones or other sounds behind you. In
systems configured without rear speakers, the settings affect the side out-
puts.
SUB BASS BOOST 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 adjusts the loudness of the side and rear speakers. When
there are no side speakers, it adjusts the amount of ambient signal mixed
into the main loudspeakers.
