If there is a strong monaural speaking voice present at the same time, this
component of the input to the Cathedral effect is reduced while the stereo
component is increased.
If the input signal is pure monaural speech the reverb is almost entirely
attenuated. SPEECH DETECT is a real benefit to some popular music
(where spoken voice, such as rap, occurs along with the music), stereo
television and early stereo movies.
CENTER LEVEL adjusts the output level from the center speaker.
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.
Music Logic Parameters
Music Logic is a surround effect developed specifically for music listening.
It makes full use of additional loudspeakers placed at the center, sides and
rear of the room and provides a slight degree of steering for the front
channels. (Music Surround, available in the THX and Dolby Digital
versions of the DC-1, passes unprocessed left and right information directly
to the front left and right speakers.)

Music Logic
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.
