the 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
Toggle Compression.
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. Enables
Automatic Attack and Release Mode.
Auto Mode Button
When Auto mode is active, the
Attack and Release controls become
inoperative, and a pre-programmed
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
Threshold
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
Sets and Displays the Compression
Ratio Ratio for the Selected Input Channel
or Output 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.
