Rane C 4 Quad Compressor / Limiter / Dynamic EQ £759.99
Description
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. A de-essing 'preset' in each channel is found by aligning the controls to the triangles, but with far greater control than other de-essers.
The C4 is a member of Rane's analog-controlled digital family of products, including the G4 gate, 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 dynamic equalization 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.
