CONTROLS
AND INDICATORS
Gain
The gain control is used to match the level of the signal source to the
fixed 0 dBV threshold of your Compressor/Limiter. It should
be adjusted so
the yellow threshold indicator illuminates only when the signal reaches the
maximum level desired. Then, above this level, the Compressor/Limiter will
tend to minimize further increases in level.
Ratio
This control determines the ratio of change in output level to changes in
input level for all signals
above threshold. The numbers printed around the
Ratio control are calibrated in dB and indicate the dB increase in input above
threshold
required to produce a 1 dB increase in output. This can be
expressed conveniently as a ratio. If the output remains constant no matter
how high the input level, we have an infinite (cc) input/output ratio. It should
be remembered that the Ratio control has no effect on signals which are
below threshold, since the CL-SERIES products do not alter signals at below-
threshold levels.
There is a common but incorrect notion that limiting always implies the
use of an infinite ratio. Although there are times when an infinite ratio is
desirable, there will be situations where infinite, or "hard", limiting action is
neither appropriate nor necessary. In fact, it should be noted that an infinite
ratio setting
is likely to cause noticeable side effects
in the sound, and may
not be usable on programs where subtle control is desired.
Attack Time
The response of the compressor/limiter to signal levels above threshold
is further defined by the ATTACK TIME control. Attack time is the amount
of time that the unit takes to attenuate the output level after threshold has
