The C400 is a professional 4 channel compressor that can be operated as 4 separate
processors or linked as two independent stereo pairs. In Link mode, Channel 1 and 3
provide Master control and 'rms summing' is used to ensure that signals from both the
linked channels affect compression equally.

Each channel has fully variable controls for Threshold, Ratio, Release and Gain.
Compression slope can be switched between Hard or Soft knee, with Hard knee
providing tight control of compression Ratio and Soft knee a more progressive style of
compression.

Two Attack/Release modes are available; Auto Attack/Release or Program Dependant
Attack with manually adjustable Release. A low frequency Program filter can be switched
into the sidechain to reduce the effects of bass heavy material causing over compression.
Each channel also has a sidechain insert on TRS jack to allow connection of external
processing such as an equaliser.

Gain Reduction is displayed on an 8 segment LED bargraph. The Bypass and Link
switches also have led indicators.

All inputs and outputs are electronically balanced and can be switched between +4dBu
and -10dBV operating levels.
