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
