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.
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 Attack. Sets and
Displays the Compressor Attack
Setting for the Selected Input
Channel or Output Bus.
This encoder sets, and the meter
displays, the compressor’s attack
setting for the selected channel
or output bus. Attack sets the
speed at which the compressor
acts on the input signal. A slow
attack time (fully clockwise)
allows the beginning component
of a signal (commonly referred
to as the initial transient) to
pass through, uncompressed,
whereas a fast attack time (fully
counterclockwise) triggers
compression immediately when
a signal exceeds the threshold.
You can set the attack from
0.2 to 150 milliseconds.
Compressor Release. Sets and
Displays the Compressor Release
Setting for the Selected Input
Channel or Output Bus.
This encoder sets, and the
meter displays, the release
setting of the compressor for
the selected channel or output
bus. Release sets the length of
time the compressor takes to
return the gain reduction back
to zero (no gain reduction) after
crossing below the compression
threshold. Release can be set
from 2.5 to 900 milliseconds.
Power User Tip:
Very short release
times can produce a choppy or
“jittery” sound, especially when
compressing instruments that
have a lot of low-frequency
components, such as bass guitar.
Very long release times can result in
an overcompressed, or “squashed,”
sound. All ranges of release can be
useful, however, and you should
experiment to become familiar
with different sonic possibilities.
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.
Equalizer On/Off Button
(32.4.2AI and 24.4.2AI only).
Globally switches all EQ Bands On
or Off for the Selected Input
Channel or Output Bus.
This button engages or
disengages the equalizer for the
selected channel or output bus.
It will illuminate to indicate that
the equalizer has been enabled.
The equalizer is available
for all 32/24 input channels
and every output bus.
