4.1 The Fat Channel
Compressor Sets and Displays the Compressor
Attack 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 Sets and Displays the Compressor
Release 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 40 to 1,000
milliseconds.
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 Sets and Displays the Amount of
Makeup Gain 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.

Fat Channel Equalization Section
Equalizer Turns the Equalizer On and Off for
On/Off the Selected Channel or Output Bus.
Button
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 input and output buses.
Low EQ Activates Control for the Low Band
On/Off EQ for the Selected Input or Output
Button Bus.
This button actives control of the
equalizer's Low band for the selected
channel or bus. The button will
illuminate to indicate control is active.
The Low EQ band is available for
all input and output buses.
Low EQ Sets and Displays the Center
Frequency Frequency of the Low EQ Band.
Control
This encoder sets, and the meter
displays, the center frequency of the
equalizer's Low band. The center
frequency is the middle of the
passband (the mean) between the
lower and upper cutoff frequencies
that define the limits of the band.
You can adjust the center frequency
from 30 to 555 Hz.

Fat Channel 4.1
Low EQ Q Sets and Displays the Q of the Low
Control Frequency Band.
This encoder sets, and the meter
displays, the Q for the Low band.
The Q is the ratio of the center
frequency to the bandwidth. When
the center frequency is constant, the
bandwidth is inversely proportional
to the Q, so as you raise the Q, you
narrow the bandwidth.
Low EQ Gain Sets and Displays the Gain
Control Attenuation or Boost of the Center
Frequency.
This encoder sets, and the meter
displays, the gain cut or boost at the
center frequency for the Low band.
The level of the center frequency can
be set between -15 and +15 dB.
