OUTPUT / LEVEL and LIMITER
A Limiter works like a very fast compressor with an infinite:1 compression ratio and
limits the output level to whatever is set by the threshold.
In CQ, the limiter is applied post fader, meaning that it can be set for use on an
output for monitoring and prevent the output signal rising above a set level, even if
the output level fader is adjusted by a musician using CQ4You for example.
Fast/Slow – Select the speed of the Limiter on the signal.
Threshold – Set the level when the limiter will be triggered (effectively maximum
output level).
In/Out – Enable or disable the Limiter.
