Gate Release. Sets and Displays
the Rate at Which the Gate Closes
on the Selected Channel.
This encoder sets, and the meter
displays, the rate at which the
gate for the selected channel
closes. The release time can be
set from 0.05 to 2 seconds.
Power User Tip: Gate-release
times should typically be set so
that the natural decay of the
instrument or vocal being gated is
not affected. Shorter release times
help to clean up the noise in a
signal but may cause “chattering“
with percussive instruments.
Longer release times usually
eliminate chattering and should
be set by listening carefully for the
most natural release of the signal.
Compressor On/Off. Turns the
Compressor On and Off for 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 Toggle Button.
Engages Soft-Knee Compression.
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 Button. Enables
Automatic Attack and 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 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.
