Chapter 17: Dynamics
127
To adjust Exp/Gate parameters in Channel Control:
1
Press or rotate an encoder (1-8) corresponding to the desired
parameter (Threshold, Ratio, Attack, Knee, Release, Gain, Key
HF and Key LF).
2
Press the encoders for Key to engage/disengage Key HF or
Key LF.
To bypass the current dynamics processor:
Press the Channel Control In switch.
Expander/Gate Parameters
The Exp/Gate parameters can be adjusted using the Channel
Control encoders (in Exp/Gate mode) or on-screen.
Threshold
Increases or decreases the threshold level for the
built-in Expander/Gate.
Ratio
Increases or decreases the ratio for the built-in Ex-
pander/Gate. The most extreme clockwise setting (100:1) puts
the process into Gate mode.
Attack
Increases or decreases the attack time for the built-in
Expander/Gate.
Gate Hold
Increases or decreases the time the built-in gate
holds.
Release
Increases or decreases the release time for the built-in
Expander/Gate.
Range
Sets the maximum range or depth of attenuation of the
gate on that channel.
In/Out
Takes the built-in Expander/Gate in or out of circuit
(bypass).
Side-Chain Keying
The Expander/Gate supports side-chain and
key listen. For details, see “Side-Chain Keys and Filters” on
page 131.
Exp/Gate Gain Reduction Meters
A single bi-color Gate LED on each input channel indicates
Exp/Gate activity, as shown in the following table.
Six-segment gain reduction meters are provided in the ACS for
metering of the Exp/Gate on the currently selected channel.
Expander/Gate Defaults and Ranges
The following table lists the default values for the Ex-
pander/Gate:
