Input Channel - Compressor - QSC TouchMix-30 Pro User Manual

Input Channel – Compressor
Input Channel − Compressor
The Compressor controls the dynamic range of a signal
above a set Threshold.
1. Comp tab – Selects the Compressor screen.
2. Comp In / Out switch – Engages and disengages
the compressor.
3. Knee In button
– Determines how
abruptly the compressor
transitions in and out of
gain reduction as the
threshold is crossed.
4. Simple button – Turns
Simple mode on and off. Hides all controls except:
• Comp In
• Simple
• Reset
• Compression
5. Reset button – Sets all the Comp controls to their
factory default position.
6. In meter – RMS input level
7. N.R. meter – Gain Reduction – (red) indicates
how much the signal is being reduced by the
compressor.
8. Out meter – Output level after any applied
compression
9. Threshold slider – Sets the point at which the compressor will begin to reduce signal level.
10. 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 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. Ratio slider – Sets the ratio of input level to output level when the signal exceeds the threshold.
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. Nain knob – (Compressor only) Adjusts the overall output gain to makeup any loss after the signal is compressed.
15. Compressor indicator – When the Compressor is In, an orange "C" displays on the channel controls strip.
16. De-Esser knob – Adjusts the amount of compression at the frequencies of sibilant consonants such as "s", "z", and "sh".
17. De-Esser button – Engages or disengages the De-Esser.
18. Side Chain selector – Selects another input channel to control the compression of the currently selected channel. Touch the Side Chain
selector box then use the Master Encoder to adjust.
19. Side Chain In – Engages or disengages the side chain. When the side chain is disengaged, the input of the currently selected channel controls
its own compression.
