sor in that band. This prevents the muted compressor’s sidechain from producing a
gain reduction signal that could couple into unmuted bands through the various
band-coupling controls.
Please note that a single band will interact with the back-end clipping system quite
differently than will that band when combined with all of the other bands. There-
fore, do not assume that you can tune each band independently and have it sound
the same when the clipping system is processing all bands simultaneously.
Compression Threshold; Speech Compression Threshold controls set the com-
pression threshold for music and speech in each band (following the 8600Si’s auto-
matic speech/music discriminator), in units of dB below the final clipper threshold.
We recommend making small changes around the factory settings to avoid changing
the range over which the
MB C
LIPPING control operates. These controls will affect
the spectral balance of the processing above threshold, but are also risky because
they can significantly affect the amount of distortion produced by the back-end
clipping system.
You can use these controls to set independent frequency balances for music and
speech (page 3-70).
