Fat Channel Compressor Section
Compressor
Turns the Compressor On and Off for the
On/Off
Selected Channel or Output Bus.
This button engages or disengages
the compressor for the selected
channel or output bus. It will
illuminate to indicate that the
compressor has been enabled.
The compressor is available for all input and
output buses.
Soft Knee
Engages Soft-Knee Compression.
Toggle Button
In normal operating mode, the
compressor is set for hard-knee
compression, meaning that the
gain reduction applied to the
signal occurs as soon as the signal
exceeds the level set by the
threshold. When the Soft Knee
button is engaged, the onset of
gain reduction occurs gradually
after the signal has exceeded
the threshold.
Auto Mode
Enables Automatic Attack and
Button
Release Mode.
When Auto mode is active, the
Attack and Release controls
become 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
Sets and Displays the Threshold of the
Threshold
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.
Compressor
Sets and Displays the Compression Ratio
Compression
for the Selected Input Channel or Output
Ratio
Bus.
This encoder sets, and the meter
displays, the com pression 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.
