VocoPro CLG-600 owner manual 0-30 dB

Front Panel Description and Controls (cont.)

4.IN/OUT button - This switch enables you to quickly hear the CLG-600 compressor/limiter IN or OUT of the audio chain. When the switch is in the OUT position, all limiting and compression controls and functions are bypassed, with the exception of the gain and output controls, which continue to function as straightforward level controls.

5.THRESHOLD control - The THRESHOLD control has a range of -40dB to +20 dB, allowing applications from low level compression to high level limiting. The THRESHOLD control determines the audio level above which GAIN REDUCTION occurs. When the THRESHOLD LED comes on, that means that GAIN REDUCTION is beginning to occur, due to input signal peaks exceeding the selected threshold in dB.

8.RELEASE control - The RELEASE control determines how fast or slow a compressed segment returns to its original volume. The available range is from .05 to 4 seconds. This control when used correctly creates either a

9.AUTO/MANUAL switch - By activating the AUTO switch to the ON position, the attack and release controls are handled by the CLG-600 automatically. When it is set to the MANUAL position, the attack and release controls will adhere to settings of the controls in place. This allows for unobtrusive musical compression with widely varying dynamics to occur without "manning" the sound system.

6.RATIO control - 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 increase in input (above threshold) required to produce a 1db 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 input/output ratio.

NOTE: It should be remembered that the RATIO control has no effect on signals which are below threshold. 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.

7.ATTACK control - ATTACK controls how fast the compressor reacts to signals passing over the threshold point. The available range is from 0.1 to 200 ms. This control when used correctly creates either a smooth or abrupt signal process.

10.OUTPUT LEVEL control - OUTPUT Level control is provided to fully cut or restore up to -/+ 20 dB of system gain. For unity gain, set the control to 0.

NOTE: When the unit is in the BYPASS mode the output control still functions.

11.GAIN REDUCTION meter - This 8-stage LED meter indicates the actual GAIN REDUCTION processing level and displays this in range

of 0-30 dB.

12.LEVEL EXPANSION meter - This 8-stage meter indicates the actual LEVEL EXPANSION level and displays this in a range of -30dB to +6dB.
