6.7.2 Gate/Expander
Figure 6-16 GATE (top) and EXP Touchscreens
The Gate/expander has five controls and an on/off
switch. There is a mode button to switch between the
gate and downward expander.
The
IN/OUT
meters show the levels coming in/out of
the gate/expander. The inverted
REDUCTION
meter
displays the gain reduction.
The graph summarizes the gate/expander’s parameter
settings.
Threshold
The
THRESH
control adjusts the level below which
attenuation begins. It is adjustable in the range -60 to -1
dBFS in increments of 0.1 dBFS. The default threshold
value is -1 dBFS.
Range/Ratio
In Gate mode, the
RANGE
control sets the amount of
attenuation that occurs when the signal drops below the
Threshold. The
RANGE
is variable from -100 dB to -1 dB
in increments of 0.1 dB. The default is -100 dB.
In Expander mode, this setting is called
RATIO
and
sets the expansion gain reduction ratio from 1:1 to 1:
∞
.
The default is 1:
∞
.
Hold
The
HOLD
control adjusts the time the Gate/Expand-
er stays open after the signal drops below the threshold
before gain reduction begins.
HOLD
is adjustable in the
range 0–5 s; the default is 0 s.
Attack
The
ATK
control adjusts the time for the gate to open
and pass the signal through once the signal exceeds the
threshold after reduction has occurred.
ATK
is adjust-
able in the range 1–30 ms.
ATK
is scaled such that the
faster settings can have finer adjustments. The default
ATK
is 1 ms.
Release
The
REL
control adjusts the time for the gate to close
and begin gain reduction after the signal drops below
the threshold and the hold time has passed.
REL
is ad-
justable from 50 ms to 3 s and is scaled such that faster
settings can have finer the adjustments. The default
REL
time is 250 ms.
Expander/Gate Mode
The
EXPANDER/GATE
switch toggles from Gate
to Expander. It is accessible only from the GATE/EXP
Touchscreen, not from DYNAMICS. In Expander mode,
the,
HOLD
,
ATK
and
REL
controls operate the same
as in Gate mode but the
RANGE
control is displayed
as
RATIO
. This can produce smoother sounding gain
reduction in many situations.
In Expander Mode,
RANGE
is replaced by
RATIO
that sets the rate of gain reduction as the signal drops
below the Threshold. Ratio is variable between 1:20
(maximum gain reduction) to 1:1 (no gain reduction).
As
RATIO
approaches to 1:1, the resolution between
values increases.
