Gate Parameters:
GATE On/Off [53] Gate on/off.
GATE THRS [54] The gate threshold level can be adjusted in 1 dB steps from 0 dB
FS
to
–96 dB
FS
.
GATE REL [55] The gate release time can be adjusted in 13 steps within a 10 ms through
10 s range (10 ms, 20 ms, 30 ms, 50 ms, 100 ms, 200 ms, 300 ms, 500 ms,
1 s, 2 s, 3 s, 5 s, and 10 s).
GATE hold on/off [56] Hold on = 150 ms, off = 0 ms.
GATE ATCK [57] The gate attack time can be adjusted in 9 steps within a 200 µs to 1 ms
range (0.2 ms, 0.3 ms, 0.4 ms, 0.5 ms, 0.6 ms, 0.7 ms, 0.8 ms, 0.9 ms, and
1 ms).
GATE hyst on/off [58] The gate hysteresis function provides an offset between the un-mute and
mute thresholds. This means the gate will remain open (un-muted) at a
lower level than the level than was required to open it. For example, a
threshold can be set so that amp noise from an electric guitar will be at-
tenuated until the guitar is played. However, as the guitar sustains and
loses energy (level) over time, the gate will remain open at levels below
that which caused it open in the first place (un-mute threshold). Once the
level falls far enough, the gate will close (mute) again.
GATE ATTN [59] The attenuation level can be adjusted in 1 dB steps from 0 dB
FS
to
–48 dB

Parameters Shared by the Dynamics Functions:
SC LINK [60] The Side-Chain Link function allows to form a side-chain group from up
to eight channels in order to control the dynamics of all of them by the
maximum level of all side-chain group members. Side-chains are defined
in the GC’s Channel Patch window. The rotary encoder switches the side-
chain link function on/off, if it is available for the specified channel.
SC LINK intKey/extKey [61] The key source input can be selected from intKey (dynamics processing
depends on the channel’s input signal), or extKey (processing is controlled
by a signal connected via the patch).
SC HI CUT/LO CUT On/Off [62] Low-cut and high-cut filters are available within the side-chain key signal.
This facilitates frequency-dependent dynamic processing for creating ef-
fects, such as de-essing. Both side-chain filters can be switched on/off in-
dependently.
