Compressor Auto Mode
Button. Enables Automatic
Response Mode.
When Auto mode is active,
the Response control
becomes inoperative, and a
preprogrammed attack and
release curve is used. In this
mode, the attack is set to 10 ms,
and the release is set to 150 ms.
All other compressor parameters
can still be adjusted manually.
Compressor Threshold. Sets
and Displays the Threshold of the
Compressor for the Selected
Channel or Output Bus.
This encoder sets, and the
meter displays, the compressor
threshold for the selected
channel or output bus. When
the signal's amplitude (level)
exceeds the threshold setting,
the compressor engages. Turning
the knob counterclockwise
lowers the threshold so that
compression begins at a lower
amplitude. The threshold can
be set from -56 to 0 dB.
Compression Ratio. Sets and
Displays the Compression Ratio
for the Selected Input Channel or
Output Bus.
This encoder sets, and the
meter displays, the compression
ratio (or slope) for the selected
channel or output bus. The ratio
sets the compression slope,
which is a function of the output
level versus the input level. For
example, if you have the ratio
set to 2:1, any signal levels above
the threshold setting will be
compressed at a ratio of 2:1. This
means that for every 2 dB of level
increase above the threshold,
the compressor's output will
only increase 1 dB. The ratio
can be set from 1:1 to 14:1.

Compressor Response. Sets and
Displays the Compressor
Response Setting for the Selected
Input Channel or Output Bus.
This encoder sets, and the meter
displays, the compressor's
response setting for the selected
channel or output bus. The
Response control sets the
attack and release tapers for the
Compressor simultaneously. A
tight response time triggers the
compressor immediately and
returns the gain reduction back
to zero quickly when the signal
drops below the compressor
threshold. A smooth response
time allows the beginning
component of the signal or
"initial transient" to pass through,
uncompressed, and extends the
time of length of time before the
gain reduction returns to zero.
Power User Tip: In general, a
tighter response time should be
used for instruments with relatively
few transients, like drums and
percussion, while a smooth setting
should be using for instrument
with a lot of transients, like vocals
and stringed instruments.
Compressor Makeup Gain. Sets
and Displays the Amount of
Makeup Gain for the Compressor
on the Selected Input Channel or
Output Bus.
This encoder sets, and the meter
displays, the makeup-gain
setting of the compressor for the
selected channel or output bus.
When compressing a signal, gain
reduction usually results in an
overall attenuation of level. The
gain control allows you to restore
this loss in level and readjust the
volume to the precompression
level (if desired). You can adjust
Makeup Gain from 0 dB (no
gain adjustment) to +28 dB.
