Chapter 8: Inputs and Input Routing

Using Built-In Dynamics and EQ
Each Input Channel has built-in Dynamics processors, a
High-Pass Filter and a 4-band EQ; each FX Return has a
built-in 2-band EQ. If the channel is a stereo channel, the pro-
cessor controls are linked and apply to both the left and right
sides of the channel. Built-in EQ processors are controlled
from the Channel Control section of the ACS.
Using Dynamics on Channels
A built-in Compressor/Limiter and Expander/Gate are avail-
able on each Input Channel. Controls for all of the built-in dy-
namics processors are provided in the Channel Control sec-
tion, and an input/output curve appears on-screen.
Compressor/Limiter
To engage and adjust the built-in Compressor/Limiter:
1
Target a channel by pressing its Select switch.
2
Press the Comp/Lim switch in the Channel Control section.
The switch lights to indicate control of the Compressor/Lim-
iter.
3
Engage the built-in processor by pressing the In switch in
the Channel Control section.
4
Press and/or adjust the Channel Control encoders for the
displayed parameters.
Expander/Gate
To engage the built-in Expander/Gate on the selected channel:
Press the Exp/Gate switch in the Channel Control section.
To adjust Expander/Gate controls:
1
Target a channel by pressing its Select switch.
2
Press the Exp/Gate switch in the Channel Control section.
The switch lights to indicate control of the Expander/Gate.
3
Press the In switch to engage the built-in expander/gate.
4
Press and/or rotate Channel Control encoders to adjust the
displayed parameters.
Using Built-In 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. Controls for built-in EQ processors are in the Channel
Control 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:
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
switch in the Channel Control section, then press the
Channel Control In switch to put the EQ in circuit.
