You can enable the sidechain filter with the green enable
button.
After the sidechain signal has been processed by the
sidechain filter it is measured by a level detector that deter-
mines the instantaneous level of the signal (in the case that
ChannelStrip is running in stereo mode the detector is linked
with the other channel in the stereo pair and the higher level
of the two channels is used). The measurement made by the
level detector is indicated by the orange triangle in the com-
pressor input meter. The channel signal is delayed by 8 sam-
ples relative to the detector signal to allow the compressor to
have an instantaneous attack when the “Attack” parameter is
set to 0.
When the compressor is enabled using the orange “Comp
Enable” button the signal will be attenuated based on how
much the detected level is above the threshold you set with
the “Thres” knob and what compression ratio is set with the
“Ratio” knob.
The dynamic behavior of the opening and closing of the gate
is controlled with the “Attack” and “Release” knobs and the
compressor character switch.

Compressors are important in controlling the dynamic range
of the source material you are working with. While the
instruments, your ears, the microphones and your digital
audio workstation all have dynamic ranges that are greater
than 100 dB, most reproduction and delivery media have
significantly reduced dynamic ranges. Compression is used,
in its simplest form, to help reduce the dynamic range of
