3.3.9 Expander/Gate Parameters
Press GLOBAL VIEW: EXP-GATE.
This view enables the user to control the most important parameters of the
dynamics section’s expander and gate parts. The complete parameter set is
available on the channel-related dynamics view, refer to chapter 3.4.2. In
that chapter you will also find the parameter details.
Please note: The expander and gate parts of the dynamics section can be
activated simultaneously with the EXP GATE hardware key below the
channel meters – in addition to the individual on/off keys described below.
EXP On/Off Expander on/off.
EXP THRS The expander threshold level can be adjusted in 1 dB steps from 0 dB
FS
to
–96 dB
FS
.
EXP RTIO The expander ratio can be adjusted from 1:1 (no expansion) to 20:1 (heavy
expansion).
GATE On/Off Gate on/off.
GATE THRS The gate threshold level can be adjusted in 1 dB steps from 0 dB
FS
to
–96 dB
FS
.
GATE ATCK The gate attack time can be adjusted in 9 steps within a 200 µs to 1 ms
range.
GATE hyst on/off 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.
