Compressor & Expander

The following

parameters apply to both the Compressor and the
Expander. The only difference is that compression
limits levels above the threshold setting while expan-
sion lowers levels below the threshold setting.

Gain dB

Use this fader to adjust the selected chan-

nel’s gain (±20 dB) post dynamics processing.

Ratio

This fader adjusts the compression ratio (from

1:1 to infinite). For example, with a setting of 4:1, for
every 4 dB of input gain above the threshold, 1 dB of
gain is output.

Threshold dB

Use this fader to set the threshold at

which the dynamics processing is active.

Attack ms

This fader sets the attack time (0 to 125

ms) for the dynamics processor. Higher values pro-
duce slower attack times, thus allowing more of the
transient through.

Release ms

This fader sets the release time (1 to

5000 ms) for the dynamics processor.

TIP

To gain control of the

DYNAMICS

module’s faders via the

LCD’s soft knobs, recall the LCD’s

MIXER CHANNEL

press

CHANNEL

in the

MAIN DISPLAY MODE SECTION

.

Then press the

AUX DYN

soft key to reach the

AUX DYN

control screen.

BYPASS

Press this key to turn dynamics processing

on and off for the selected channel.

Gate

The following three parameters are unique to

the gate algorithm:

Rge dB

This slider determines the range of the gate,

which is the amount of attenuation when the gate
closes. The default is –30 dB, but the range is from 0
to –60 dB.

Hold ms

Determines the duration that the gate will

remain open without being re-triggered.

Hyst dB

Short for Hysteresis, this parameter pro-

vides a way of fine-tuning the clamping action of the
gate. The higher the value, the less “gate chatter”,
which often happens with gates as the input signal
remains very close to the gate threshold.

COMP

Use this key to select the type of dynamics

processing you want on the selected channel: com-
pressor, expander, or gate. The key’s label changes
according to the selection. Use your mouse to click
on the key and bring up the dynamics menu.

MAKEUP

Use this key to compensate for level lost

during compression.

SELF

This key selects a trigger source for the selected

channel’s dynamics processor (the audio signal that
dictates how the dynamics will behave). The selec-
tions are:

Self

,

Side

, or

Both

.

Self

This setting uses the selected channel’s audio

to trigger the dynamics processor. It is the default
setting.

Side

This setting uses an adjacent channel’s (the

channel that would be part of a linked pair—see
“Links” on page 69) audio to trigger the dynamics
processor. This is commonly referred to as a “side-
chain”. It is important to note that while the dynam-
ics processor’s input is being controlled by the other
channel in this case, the selected channel’s audio is
the one affected by the processing.

Both

This setting uses the audio from both chan-

nels to trigger the dynamics processor. The effect is
like having a linked pair strapped to one compressor
setting, with the exception that the audio from the
channel providing the “Side” input is not affected.

LIBRARY

Use this key to display the Dynamics

Library. For example, If the

LIBRARY

window cur-

rently shows the EQ Library, pressing this key will
override that display and recall the Dynamics Library
instead.
