SPEECH DETECT The Speech Detection circuit 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 Ambience algorithm is reduced while the
stereo component is increased.
If the input signal is pure monaural speech the input is almost entirely
attenuated. SPEECH DETECT is a real benefit to some popular music
(where spoken voice, such as rap, occurs along with music), stereo televi-
sion, and early stereo movies. Any stereo material which was not carefully
mixed for Surround is a good candidate for playing through Ambience with
SPEECH DETECT on.
SUB BASS BOOST boosts or cuts the subwoofer output level. Although the
normal subwoofer level was set during the initial calibration procedure,
with some recordings you may find it desireable to increase or decrease this
deep bass level.
In Ambience, MAIN MUTE mutes allows you to hear only the CP-3

generated effects; EFFECTS MUTE allows you to hear the original, unproc-
essed stereo signal.
Note that the S/N Optimizer is not active in this mode.
