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”.
