Chapter 7: Inputs and Input Routing 71
Compressor/Limiter
To engage the built-in Compressor/Limiter on the selected
channel:
Press the Comp/Lim In switch in the ACS Dynamics sec-
tion.
To engage the built-in Compressor/Limiter on any input channel:
1 Bank to the desired channels.
2 Press the Comp Thrs switch to assign the input encoders to
the built-in Compressor/Limiter.
3 Push the assignable encoder on each channel you want the
built-in Compressor/Limiter engaged.
To adjust the Compressor/Limiter threshold from a channel:
1 In the Encoder Assignment section, press the Comp Thrsh
switch.
2 Turn the assigned rotary encoder to set the Compres-
sor/Limiter threshold value.
To adjust Compressor/Limiter controls from the ACS:
1 Target a channel by pressing its Select switch.
2 Press the Select switch next to the Comp/Lim In switch in
the ACS Dynamics section. The switch lights to indicate con-
trol of the Compressor/Limiter.
Expander/Gate
To engage the built-in Expander/Gate on the selected channel:
Press the Exp/Gate In switch in the ACS Dynamics section.
To engage the built-in Expander/Gate on any input channel:
1 Bank to the desired channels.
2 Press the Gate Thrs switch to assign the input encoders to
the built-in Expander/Gate.
3 Push the assignable encoder on each channel you want the
built-in Expander/Gate engaged.
To adjust the Expander/Gate threshold from a channel:
1 In the Encoder Assignment section, press the Gate Thrsh
switch.
2 Turn the assigned rotary encoder to set the Expander/Gate
threshold value.
To adjust Expander/Gate controls from the ACS:
1 Target a channel by pressing its Select switch.
2 Press the Select switch next to the Exp/Gate In switch and
meter in the ACS Dynamics section. The switch lights to indi-
cate control of the Expander/Gate, and indicator LEDs below
each encoder light red to show that these controls are mapped
to Exp/Gate functions.
Using EQ on Channels
A built-in High-Pass Filter and 4-band EQ are available on each
Input Channel and a 2-band EQ is available on each FX Re-
turn. Modular controls for all of the built-in EQ processors are
in the ACS EQ section, and an EQ response curve appears
on-screen.
One of two EQ types can be selected for the built-in EQ, on a
per-channel basis: a full-spectrum parametric digital EQ or an
analog-modeled EQ.
To use the built-in EQ on a channel, do one of the following:
1 Target the channel by pressing its Select switch.
2 Do any of the following:
• To engage the channel High-Pass Filter, press the HPF
switch in the Encoder Assignment section. Toggle HPF
in/out on each channel by pressing its encoder; adjust
HPF frequency by rotating its encoder.
• To engage the built-in 4-band or 2-band EQ, press the
EQ In switch at the bottom of the ACS Equalizer section.
Using Inserts on Channels
You can use software plug-in inserts or hardware inserts on
any Input Channel or FX Return.
Using Plug-In Inserts on Channels
Plug-Ins are arranged in virtual racks, which allow signals to
be sent to and from each plug-in as if it were an external pro-
cessor. Plug-Ins can be used in two ways: as inserts, or as ef-
fects in a Send/Return arrangement.
Insert The plug-in is patched in at the insert point on an Input
Channel or FX Return. Each Input Channel may have up to
four plug-in inserts.
Send/Return Signal is sent to the plug-in over any of the sys-
tem busses (usually an Aux Send) and routed back to an Input
Channel or FX Return.
For more information on using plug-ins in a Send/Return ar-
rangement, see “Using Plug-Ins as a Bus Processor” on
page 156.
