QUICK START - 

IF YOU JUST CAN’T WAIT

If you are familiar with compressors,
limiters, gates and de-essing techniques
this quick guide is probably all the
information you will need to operate the
C400XL. For more information, please refer
to other sections of this manual.

• Unpack the C400XL and check for possible

damages that could have been caused by
transport. 

• Read the safety instructions.
• Take a few minutes to register online via:

The C400XL is a compressor/de-esser -
gate/expander with two independent channels
that can be routed either in serial (stereo) or
dual mono mode.

Routings

The C400XL has two routing options. Dual
Mono  or Stereo/Serial. The Routing mode is
set on the C400XL front panel on the far left. 

Dual mono

- where C400XL is split and operates as two
100% separate mono engines. A typical
application for this mode is using the two
engines as insert effects on two different
channels.

Stereo/Serial Mode

- utilizing both effect engines in serial. Engine

1 is feeding Engine 2. This is the mode to

choose if you wish to process a signal with both
processing engines. Note that this routing
works for both a stereo setup but also a single
mono setup. Typically you would use one
engine as a gate/expander and the other as de-
esser or compressor/limiter. But note that any
combination of effects is possible as the
engines operate independently.

• Make all appropriate connections. You may

refer to the examples on pages 10-11.

• Decide application and set Routing

accordingly.

• Set MIX to 100% for normal compression.

Any setting between 0 and 100% utilizes the
C400XL “new compression style”, based on
parallel compression. Read the section “New
Style Compression”

• Select desired processing  type on the two

Engines.

• Start playing.
• Feed the C400XL channels with an

appropriate level. The yellow -3 LED should
only be lit at peaks. The level is set on the
sending device.

• Set MIX depending on your intentions and

selected effect.

• Now tweak the THRESHOLD, MAKE-UP

GAIN and RATIO controls for the two
engines until you have the intended result.
