Gate
Unlike the compressor, gate mode has only one style. While the dynamic section is
addressing the gate, all of its controls are enabled except the make up control knob
and the MODE and KNEE buttons.
Item Description
1 Up/down select buttons, for swapping dynamic section control from
compressor to gate, and vice versa.
2 Gate range control knob, adjusts 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.
3 Quick access button, which directly selects the compressor or gate detail
areas on the input channel strip.
4 To aid set up, the gate has a side chain listen that sends the side chain onto
a solo bus. This 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 255.
5 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.)
6 attack control knob, adjusts time taken for gate to open after an over-
threshold signal. Range is from 0.02ms to 20ms (milliseconds).
7 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).
8 threshold control knob, sets signal level at which gate opens. Range is
from -50dB to +25dB.
9 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).
