Rane C4 Quad Compressor

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.
