Quad Compressor/Limiter/De-Esser 


The C4 Quad Compressor / Limiter / Dynamic Equalizer presents matchless feature, performance and ergonomic value. The C4 offers four feature-packed channels of compression and limiting in a 2U package. Internal and external side-chain options offer a fully adjustable parametric EQ for frequency-dependent compression or de-essing. The oversampled brick wall limiter determines the maximum output level and operates independent of the compressor. Adjacent channels link in a master/slave arrangement to ensure accurate tracking of stereo inputs. Intuitive meters show side-chain level relative to Threshold, gain reduction and complete dynamic range at a glance.


Analog controls (knobs, sliders) allow a performer or sound engineer to make precise adjustments in real time. Digital signal processing (DSP) provides a degree of accuracy, consistency and flexibility that simply cannot be matched with a traditional analog design.

The C4 combines the best of both worlds by using analog controls and high performance digital processing to achieve an unprecedented feature set. Benefits of this approach:


Allows the use of advanced compression and dynamic EQ techniques which are difficult or costly to implement in traditional analog designs.


Improved accuracy and repeatability.

Exceptional immunity to RF and electromagnetic interference.

Lower cost per channel.

Independent Compressor / Dynamic EQ / Limiter per channel.

Relative-threshold Dynamic EQ remains calibrated for all levels.

Auto mode for fast setup of Attack and Release.

External side-chain with balanced / unbalanced 1/4" TRS input.

Side-chain has a parametric EQ with Compress, Dynamic EQ and Listen modes.

Adjustable soft or hard knee compression.

Independent metering: Side-chain level, Threshold indicator, Gain reduction and Limiter headroom.

Stereo Link between channels 1 and 2 or 3 and 4.

XLR and 1/4" TRS input / output connectors.

Universal internal switching power supply (100-240V).
