Input Channel − Dynamics
(Compressor / ANC)
The Input Channel Dynamics processing block may
be configured as either a Compressor or an Automatic
Gain Control (AGC).
Compressor
The Compressor controls the dynamic range of a signal
above a set Threshold.
1.
Dynamics
button – Selects the Compressor / AGC
screen.
2.
Compressor / ANC
button – Selects either
Compressor or AGC.
3.
In
switch – Engages and disengages the
Compressor or AGC processor.
4.
Knee In
button
–
Determines how
abruptly or gradually the
compressor transitions
in and out of gain
reduction as the threshold
is crossed.
5.
Simple
button
– Turns Simple mode on and off.
When on, it hides all controls except:
• Compressor / AGC
• Comp In
• Simple
• Reset
• Compression (Threshold)
All other controls remain at the value set prior to engaging the Simple mode button.
6.
Reset
button – Sets all the Compressor and AGC controls, for this channel, to their factory default position.
7.
Input
meter – Displays the RMS input signal level.
8.
Reduction
meter – The red display indicates how much the signal is being reduced by the compressor. This meter displays a signal regardless
of whether the In button is engaged or not.
9.
Output
meter – Output level after any applied compression
10.
Compressor
graph – Vertical scale from 0 dB to -60 dB; horizontal measurement is time. When engaged, the trace displays.
•
Threshold
(A) – The level at which compression begins.
•
Attack
time (B to E) – The time it takes for the compression to reach its maximum compression after the input exceeds the threshold level.
•
Ratio
(A to E) – The amount of compression applied to the signal.
•
Release
time (C to D) – The time it takes for the compressed signal to rise to the threshold level once the input level no longer exceeds
the threshold.
11.
Threshold
slider – Sets the point at which the compressor begins to reduce signal level.
12.
Attack
slider – Adjusts how quickly the compressor reacts to a signal that exceeds the threshold.
13.
Release
slider – Adjusts how quickly the compressor stops compressing when signal falls below threshold.
14.
Ratio
slider – Sets the ratio of input level change to output level change when the signal exceeds the threshold.
15.
Nain
slider – Adjusts the overall output gain to makeup any loss after the signal is compressed.
16.
Compressor in/out
indicator – When the Compressor (or AGC) is In, an orange “
C
” displays on the channel controls strip.
