4 Controls
4.1 The Fat Channel
High EQ Gain Control. Sets and
Displays the Gain Attenuation or
Boost at the Center Frequency of
the High Frequency Band.
This encoder sets, and the meter
displays, the gain cut or boost at
the center frequency of the High
EQ band. The level of the center
frequency can be set between
-15 and +15 dB.
High Shelf EQ Button. Turns on
the High Shelving EQ for the
Selected Input or Output Bus.
When the Shelf button is not
engaged, the High band is a
parametric EQ. Enabling the Shelf
button turns the High band into
a high shelving EQ that alters,
by a fixed amount, a band of
high frequencies at and above a
user-selected shelving frequency.
Power User Tip: A high shelving
EQ is like a treble-control knob on
a stereo. In this mode, the Center
Frequency control selects the
shelving frequency.
Limiter On/Off. Turns on the
Limiter for the Selected Input
Channel or Output Bus.
When the limiter is engaged
the button will illuminate.
The ratio is ∞:1.
The Limiter is available for
all 32/24/16 input channels
and every output bus.
StudioLive™ 32.4.2AI
Owner's Manual
Limiter Threshold (32.4.2AI and
24.4.2AI only). Sets and Displays
the Threshold of the Limiter for
the Selected Channel or Output
Bus.
This encoder sets, and the meter
displays, the threshold of the
limiter for the selected channel
or output bus. When the signal's
amplitude (level) exceeds the
threshold setting, the limiter
is engaged. Turning the knob
counterclockwise lowers the
threshold, so limiting begins at a
lower amplitude. The threshold
can be set from -28 to 0 dB.
16.4.2AI users can access the
variable Limiter Threshold control
from VSL-AI and SL Remote-AI.
