Patching in a Dynamics Processor
The Digital Recording Console 02R features comprehensive dynamics
processors for all the channel inputs, tape returns, and stereo and bus
outputs. These processors allow you to compress, expand,
compress/expand (compand), gate, or duck the signals passing through
the mixer.

The dynamics processors are generally used to correct or control signal
levels, giving you unparalleled sonic quality and flexibility. You can also
use them creatively to shape the volume envelope of a sound.

Compressor
A compressor provides a form of automatic level control. It attenuates high
levels, thus effectively reducing the dynamic range, making it much easier
to control signals and set appropriate fader levels. Reducing the dynamic
range also means that recording levels can be set higher, therefore
improving the signal-to-noise performance.

Limiting is an extreme form of compression, where the output signal is
sharply attenuated so that it cannot exceed a particular level.

Expander
An expander is another form of automatic level control. By attenuating the
signal below the threshold, the expander reduces low-level noise or
expands the dynamic range of the recorded material.

expands the dynamic range of the recorded material.
Compander
A compander is a compressor/expander – a combination of signal
compression and expansion. The compander attenuates the input signal
above the threshold as well as the level below the width. For very dynamic
material, this program allows you to retain the dynamic range without
having to be concerned with excessive output signal levels and clipping.

Gate and Ducking
A gate, or noise gate is an audio switch used to mute signals below a set
threshold level. It can be used to suppress background noise and hiss from
valve (tube) amps, effects pedals, and microphones.

Ducking is used to automatically reduce signal levels when the level of a
source signal exceeds a specified threshold. It is used for voice-over
applications where, for example, level of background music is
automatically reduced, allowing an announcer to be heard clearly.
