Make Up Gain

During compression the signal is attenuated, gain may be required to produce the required output level. The

amount of gain required in order to bring the signal level to the same is at input is displayed on the G.R. meter.

Comp. Switch

A fully hard-wired bypass switch toggles the Compressor section to be active or not, and is best used for A/B

comparisons, or to remove the compressor stage from the signal path altogether.

OUTPUT

VU Meter

A backlit moving coil VU meters monitor the level of the output signal.

+10dB Pad

Adjusts the meters to show either normal output level, (and for those working at 'hot' output levels) VU +10dB

i.e. with the switch at VU +10dB, when the VU meter reads 0dB the actual level is +10dB.

Mix

A variable control that mixes a user defined amount of 'uncompressed' signal (dry) with the compressed signal

(wet) to create a 'parallel compression effect' without the need for external mixing devices. In this way the amount

of overall compression on the signal is under complete control.

Fade

After E.Q. and compression gain may be required to produce the required output level. Adjust so that the output

signal approaches the desired level only on signal peaks. Alternatively the control can be used to turn the output

level off.

Preamp Direct

A fully balanced hard-wire bypass connects the preamplifier directly to the output without passing through the

E.Q., the compressor FET's, the mix and gain controls at all. Use this to provide an ultra clean microphone

signal or to hear the effects of the E.Q. and compressor in an A/B comparison.

REAR CONNECTIONS

In addition to the instrument jack connectors located in the instrument section on the front panel there are also:

Line Input

A dedicated line level input via balanced XLR is located on the rear panel.

Mic Input

A dedicated microphone input via balanced XLR.

Preamp O/P Clean

A dedicated output via balanced XLR. The signal is derived directly from the preamplifier and does not pass

through the E.Q., compressor, saturation or output circuitry at all, providing an absolute clean signal.

Side Chain

The side chain connector is part of the compressor feedback stage and would normally be connected to a

normalised or semi-normalised pair of patchbay contacts. This would allow the user to insert additional EQ for

some de-essing, or frequency conscious compression. Connection is via an unbalanced stereo ¼" jack: ring is

signal send, tip is signal return and sleeve ground.

Output

A dedicated output via balanced XLR.
