Output Channel - Compressor / Limiter - QSC TouchMix-30 Pro User Manual

Output Channel – Compressor / Limiter
Output Channel − Compressor / Limiter
When set as a Limiter, prevents the audio level from
exceeding a preset threshold.
1. Comp / Limiter tab – Selects the Comp /Limiter screen.
Note that the label on this tab will change depending on the
setting of the Comp/Limiter switch.
2. Comp / Limiter In/Out switch – Engages or
disengages the compressor or limiter. Note that the
label on this tab will change depending on th setting
of the Comp/Limiter switch.
3. Comp/Limit switch – Selects Compressor or
Limiter mode. If "Comp" is selected, the processor
is identical in operation to the input channel
compressors.
4. Knee In button – The knee determines whether
the compressor/limiter transitions abruptly or
gradually as the threshold is crossed.
5. Simple button – Hides all controls except:
• Limiter In button
• Simple button
• Reset button
6. Reset button – Sets all the Limiter controls to their
factory default position.
7. In meter – RMS input signal level
8. NR meter – Gain Reduction – indicates how much
the signal level has been reduced by the Limiter.
9. Out meter – Output signal level
10. Threshold slider – Sets the point at which the compressor/limiter will begin to reduce signal level.
11. Limiter graph – When the Limiter is engaged, the trace is blue.
• Threshold (A) – The level at which limiting begins.
• Attack time (B to C) – The time it takes for the limiter to reach maximum limiting after the input exceeds the threshold level.
• Ratio (A to E) – The amount of limiting applied to the signal.
• Release time (C to D) – The time it takes for the limited signal to rise to the threshold level once the input level no longer exceeds the
threshold.
• Vertical scale = dB
12. Ratio slider – Sets the ratio of input level change to output level change when the signal exceeds the threshold.
13. Attack slider – Adjusts how quickly the processor reacts to a signal that exceeds the threshold.
14. Release slider – Adjusts how quickly the processor stops compressing or limiting when signal falls below the Threshold.
