4.1 The Fat Channel
Gate Range Sets and Displays the Range
of the Gate.
This encoder sets, and the meter
displays, the amount of gain
reduction that the gate will produce.
The range goes from 0 to -86 dB.
Gate Attack Sets and Displays the Gate Attack
Setting for the Selected Channel.
This encoder sets, and the meter
displays, the rate at which the gate
opens on the selected channel or
output.- You can set the attack time
from 0.2 to 150 ms.
A fast attack rate is crucial for
percussive instruments. Slow-rising
signals such as vocals and bass guitar
require a slower attack; with these
signals, a faster attack can cause an
audible click. All gates have the ability
to click when opening but a properly
set gate will never click.

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 rate
can be set from 2 to 0.05 seconds.
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.

Fat Channel Compressor Section
Compressor Turns the Compressor On and Off for
On/Off 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.
Auto Mode Enables Automatic Attack
Button 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.

Fat Channel 4.1
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.
