Cathedral Parameters

ROLLOFF mimics the absorption of the air in the hall and, typically, should
begin with a low frequency when simulating larger spaces.
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 Effect.
The Cathedral Effect uses a reverberation algorithm which emphasizes
rich, smooth reverberant decay in large spaces. As its name indicates, it
works well for simulating a space with a long reverberation time relative to
its size, such as a cathedral.

CENTER LEVEL adjusts the output level from the center speaker.
SPEECH DETECT activates a circuit that distinguishes monaural speech
from other inputs. Essentially, this control turns down the effect to make
speech clearer. Whenever stereo signals are present, the right and left input
channels are used independently as inputs to the ambience synthesis.
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.
MID RT (midrange reverberation time) is the time required for midrange
sounds to decay 60dB in level.
BASS RT (low frequency reverberation time) depends on MID RT and is
expressed as a multiplier. BASS RT should be set to 1.0 x MID RT for a more
natural effect in smaller spaces.
