Built-In Expander/Gate - DigiDesign D-Show Profile Manual

In/Out Takes the built-in Compressor/Limiter in or out of cir-
cuit (bypass). The Compressor/Limiter can be taken in or out
of circuit using the ACS Comp/Lim In switch, by clicking the
input encoder when Comp Thrs is enabled, or by clicking the
Comp/Lim button on-screen.
Dyn In Takes the currently targeted dynamics processor in or
out of circuit (this switch mirrors the In/Out switch found in
each built-in dynamics processor as well as in dynamics
plug-ins.
Dynamics plug-ins can be taken in/out of circuit from the
the ACS Dyn In switch and software screen.
Side-Chain Keying Provides side-chain and key listen. For de-
tails, see "Side-Chain Keys and Filters" on page 132.
Compressor/Limiter Gain Reduction Meters
Three-segment gain reduction meters for built-in Comp/Lim
are located in each input fader strip. These provide constant
display of gain reduction being applied on all currently
banked Input Channels by the built-in Compressor/limiter
from right to left, according to the following scale:
Channel Compressor/Limiter gain reduction meter scale
LED Gain Reduction
none 0 dB
1 (right) <= 3 dB
2 <= 6 dB
3 (left) <= 12 dB
Six-segment gain reduction meters are provided in the ACS for
higher resolution metering of the currently selected channel
or Dynamics plug-ins.
See Chapter 13, "Metering."

Built-In Expander/Gate

One built-in Expander/Gate is available on each Input Chan-
nel. The Expander/Gate defaults to expansion, or can be
switched to a gate by setting the Ratio to its maximum setting.
Mono and stereo processing are supported.
Expander/Gate Parameters
The Exp/Gate Threshold can be controlled by the assignable
input encoders by pressing the Gate Thrsh switch. All other
built-in Dynamics parameters are adjusted using the Dynam-
ics controls of the ACS, or on-screen.
The built-in Expander/Gate has the following parameters, ad-
justable from the ACS Dynamics section or on-screen:
Threshold Increases or decreases the threshold level for the
built-in Expander/Gate. Threshold can be adjusted using the
input encoders (in Gate Thrsh mode), the ACS Threshold en-
coder, on-screen using the Exp/Gate Threshold encoder, or by
dragging the Threshold handle in the on-screen Dynamics
Graph display.
Ratio Increases or decreases the ratio for the built-in Ex-
pander/Gate. The most extreme clockwise setting (100:1)
switches the process into Gate mode. Ratio can be adjusted us-
ing the ACS Ratio encoder, the on-screen Exp/Gate Ratio en-
coder, or by dragging the Ratio handle in the on-screen Dy-
namics Graph display.
Attack Increases or decreases the attack time for the built-in
Expander/Gate. Attack can be adjusted using the ACS Attack
encoder or the on-screen Exp/Gate Attack encoder.
Gate Hold Increases or decreases the time the built-in gate
holds. Gate hold can be adjusted using the ACS Comp Knee
encoder or the on-screen Exp/Gate Hold encoder.
Release Increases or decreases the release time for the built-in
Expander/Gate. Release can be adjusted using the ACS Release
encoder or the on-screen Exp/Gate Release encoder.
Gate Range Increases or decreases the maximum range or
depth of attenuation of the gate on that channel. Minimum
gate depth is 0 dB. Gate Range can be adjusted using the ACS
Gate Range encoder or the on-screen Exp/Gate Range en-
coder.
In/Out Takes the built-in Expander/Gate in or out of circuit
(bypass). The Expander/Gate can be taken in or out of circuit
using the ACS Exp/Gate In switch, by pressing the input en-
coder when Gate Thrs is enabled, or by clicking the Exp/Gate
button on-screen.
Dyn In Takes the currently targeted dynamics processor in or
out of circuit (this switch mirrors the In/Out switch found in
each built-in dynamics processor as well as in dynamics
plug-ins.
