Compressor Attack. Sets and
Displays the Compressor 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 Release. Sets and
Displays the Compressor 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.
Power User Tip: 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 Makeup Gain. Sets
and Displays the Amount of
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.
Equalizer On/Off Button
(StudioLive 24.4.2 only). Globally
switches all EQ Bands On or Off
for the Selected Input Channel or
Output Bus.
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 On/Off Button. Turns
the Low Band EQ On/Off for the
Selected Input or Output Bus.
This button activates 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 Frequency Control. Sets
and Displays the Center
Frequency of the Low EQ Band.
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.
