Sub Group − Compressor / Limiter
(TouchMix-30 Pro only)
The Compressor reduces the dynamic range of a signal
above a set Threshold. When set as a Limiter, prevents
the audio level from exceeding a pre-set threshold.
NOTE:
Compressor and Limiter have
similar controls. Some of the labels and
the color of the trace will differ.
1.
Comp tab
– Selects the Compressor screen.
2.
Comp In / Out
– Engages and disengages
the compressor.
3.
Comp / Limiter –
Changes the function of
this screen between the Compressor and the
Limiter.
4.
Knee In –
The
knee determines
whether the
compressor/limiter
transitions abruptly
or gradually as the
threshold is crossed.
5.
Simple –
Turns Simple mode on and off.
Hides all controls except:
• Comp (Limiter) In
• Comp / Limiter
• Simple
• Reset
• Compression (Limiting)
6.
Reset –
Sets all the Comp controls to their factory default position.
7.
In meter –
RMS input level
8.
G.R. meter –
Gain Reduction – (red) indicates how much the signal is being reduced by the compressor.
9.
Out meter –
Output level after any applied compression
10.
Threshold –
Sets the point at which the compressor will begin to reduce signal level.
11.
Compressor graph
– Vertical scale from 0 dB to -60 dB; horizontal measurement is time. When the Compressor is engaged, the
trace is displayed.
•
Threshold
(A) – The level at which compression begins.
•
Attack time
(B to C) – The time it takes for the compression to reach 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.
12.
Ratio
– Sets the ratio of input level change to output level change when the signal exceeds the threshold.
13.
Attack
– Adjusts how quickly the compressor reacts to a signal that exceeds the threshold.
14.
Release
– Adjusts how quickly the compressor stops compressing when signal falls below threshold.
15.
Gain
– (Compressor only) Adjusts the overall output gain to makeup any loss after the signal is compressed.
16. Compressor indicator – When the Compressor is In, an orange “C” displays on the channel controls strip. The Limiter displays a blue “L”.
