The C4 Quad Compressor/Limiter presents matchless feature, performance and ergonomic value. Rounding out Rane’s popular series of analog-controlled digital products for live sound applications, 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.
The C4 is a member of Rane’s analog-controlled digital family of products, which includes the G4 Quad Gate / Ducker / Expander, AC 24 crossover, DEQ 60 and DEQ60L graphic equalizers, and the PEQ 55 parametric equalizer.

Analog-Controlled Digital
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 de-essing 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.
