LA AUDIO C-400 C QUAD COMPRESSOR

The C400 C is a professional 4 channel compressor that can be operated as 4 separate
processors or linked as two independant 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. The 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 (program dependant) Attack/Release or Auto Attack with manuallly 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
jack. 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.

Innovation
The ARX COMPO? is a unique compressor/limiter designed for use in any
professional audio dynamics control application, packaged in a compact 1
RU chassis.The COMPO operates as two independent compressor/limiters,
with 'industry standard' variable Threshold, Ratio and Output gain controls.
A Stereo Link switch on the front panel lets both channels track as a stereo
pair in a Master/Slave configuration.
Enhance Switch
The COMPO features an 'Enhance' switch, which provides frequency restoration
to preserve the spectral balance of the audio signal, compensating for the sagging
Low and High frequency response of compressed program material.
The best way to think of it is as a 'smart' loudness control.
Wide Scale metering
There is comprehensive LED indication of all operating functions and status. Above
or Below Threshold LEDs on each channel give you instant visual confirmation of
compressor activity, as well as easy to read LED Gain Reduction meters.
Balanced Inputs and Outputs
On the rear panel, each channel has true differential Balanced inputs and outputs,
on both XLR and TRS jack connectors. Other features include an Active/Bypass
switch for each channel, and passive RFI filters on the inputs.
Universal AC Power
AC power range is a universal 100 to 120V or 220 to 240V AC, and is connected to
the unit via a removable power lead and standard 3 pin IEC connector, with built-in
fuse and voltage change switch.
ARX Quality
With its smooth compression, intuitive user friendly layout, high density precision
circuitry, and extensive user-variable operating parameters, the ARX COMPO is the
ideal installation 'set and forget' compressor, and is also equally at home in Studio,
Broadcast and Sound Reinforcement environments.

Every day, ARX Audio interface products solve audio problems for thousands of people
around the world.
