Item Control Function
1 ON switch Enables gate in the signal path. When switched off,
gate is bypassed. (Both the comp and gate switches
can be on at the same time.)
2 listen LED To aid set up, the gate has a side chain listen that
sends the side chain onto a solo bus. The side chain
listen LED indicator illuminates to warn you that
soloed material is from the side chain, and not the
main channel. For information on the side chain, see
“Side chain” on page 296.
3 threshold control
knob
Sets signal level at which gate opens. Range is from
-50dB to +25dB.
4 hold control knob Minimises chattering in conjunction with internal
hysteresis. Once the signal is detected as below
threshold, this defines a waiting period before the
gate starts to close. Range is from -0.005s to 2.000s
(seconds).
5 Up/down select
buttons
Swap dynamic section control from compressor to
gate, and vice versa.
6 ratio/range/
[range] control
knob
On the gate, this control adjusts the amount of gain
reduction applied to the signal below threshold.
Controls the maximum gain reduction that is
possible. Range is from minus infinity (-∞) to zero.
7 attack control
knob
Adjusts time taken for gate to open after an over-
threshold signal. Range is from 0.02ms to 20ms
(milliseconds).
8 release control
knob
Adjusts time taken for gate to close after programme
material falls back below threshold. Range is from
-0.005s to 2.000s (seconds).
9 Graph Shows the effects of adjusting the gate’s parameters.
10 Meter The gate meter mimics the gate meter at the top of
the input channel’s fast strip (see “Input metering” on
page 282).
