GATE
All input channel strips provide a Gate module.
Figure 8-2: The Gate module.
The gate silences the signal when the input signal’s
level drops below the
Threshold .
The rate at which the gate responds, (opens to let
signal through) is determined by the
Attack
parameter. With a short Attack time, the gate will
open as soon as the signal crosses the Threshold;
with longer Attack times, the gate will gradually
open, much like a fade-in.
When the input level falls back below the
Threshold, the time it takes for the gate to close
(how quickly the signal is attenuated), is
determined by the
Release parameter. Short
Release times will close the gate quickly, abruptly
attenuating your signal, versus longer release times,
which will gradually attenuate your signal, like a
natural fade-out.
FOUR-BAND PARAMETRIC EQ
All mixer channel strips, (except for the Monitor
bus), provide modeled, four-band parametric EQ.
Vintage EQ
Inspired by legendary British large console EQs,
the
EQ section (Figure 8-3) models the sound of the
most sought-after classic equalizers. Four bands of
center frequency parametric EQ filtering are
provided, each with a bandwidth control. The
High and Low bands include a shelf filtering
option. With 32-bit floating point precision, the
vintage EQ has been carefully crafted and
meticulously engineered to produce musical
results in a wide variety of applications.
Enabling EQ
Each band has an enable/disable button
(Figure 8-3), allowing you to enable as few or as
many bands as needed for the channel strip.

EQ filter controls
The EQ filters have three controls:
Double-click a knob to return to its default
position.
EQ filter characteristics
EQ is one of the most widely used processing tools
and can be applied to many different situations,
from minor corrective tasks to creative tone
sculpting. The four-band EQ has been designed to
