Select [L/R Mix, Left, Right, L/R Individually]
This determines how the left and right channels of the
selected Source are used for controlling the compressor.
Note that this parameter applies only to the control signal;
the effect always processes both channels of the input signal
in stereo.
L/R Mix is generally the best choice for stereo signals; this
compresses both channels equally, based on the combined
volumes of the left and right channels.
L Only and R Only use only the selected channel for
controlling the limiter; the other channel is ignored.
L/R Individually splits the effect into two separately
controlled mono compressors. When processing stereo
signals, this will cause the stereo image to shift.
Fx Control Trim
This adjusts the level of the FX Control Bus inputs.
Detection Mode
RMS bases the amount of compression on the average level,
which tends to sound more natural in most cases.
Peak does not do this averaging, and so the compressor
responds more quickly to sudden jumps in level.
Choose RMS if you want to make the overall volume more
consistent, or choose Peak if you want to be sure that even
sudden peaks are suppressed.

Side Chain Monitor
When this is On, you'll hear the control signal (as selected
by the Source parameter) through the sidechain EQ, instead
of the output of the limiter. This can be helpful when you're
tuning the EQ to emphasize or de-emphasize specific
frequencies.
To hear the output of the limiter, set this to Off.
SIDE CHAIN EQ
This multimode filter applies only to the control signal, and
not to the main audio path. Use it to alter the response of the
compressor so that it reacts (or does not react) only to
specific frequencies.
For instance, if you want the compressor to ignore cymbal
crashes, adjust the sidechain EQ to reduce the gain of
frequencies specific to the cymbals. While doing so, it may
help to turn on the Side Chain Monitor switch, so that you
can listen as you hone in on the desired frequencies.
EQ On
Switches the EQ on and off.
Type
Selects the type of filter for the sidechain. For more
information, see "Filter Type" on page 63.
Frequency [Hz]
Sets the filter's cutoff frequency.
Q
Sets the bandwidth of the EQ.
COMPRESSOR

Ratio
This determines how strong the effect of the compressor will
be, expressed by how many dB in input level over the
[RMS, Peak]
Threshold is required for a 1dB change in output level.
Output Level
Level
At 1.0:1, the compressor has no effect. At 20.00:1, a 20dB
increase in the input level (over the Threshold) results in
only a 1dB change in output. At Inf:1, the compressor
becomes a brick-wall limiter; once the signal hits the
Threshold, the output level will no longer increase,
regardless of the input level.
[Check-box]
Threshold [dB]
Compression happens only when the input signal exceeds
this level. Input levels above the threshold will be
compressed, and input levels below the threshold will not be
compressed.
Soft Knee Width [dB]
Increasing this value will produce a more gentle volume
change around the Threshold level.
