DC-1 Effects

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. In systems configured without rear speakers, the settings 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. In

systems configured without rear speakers, the settings affect the side out-

puts.

CENTER LEVEL adjusts the output level from the center speaker.

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.

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 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.
