The C1 is a frequency-selective dynamic processor allowing two simultaneous dynamic processes. It is an expert tool for any application requiring compression, expansion or gating. Select any frequency range, then apply a dynamic process to that range, or use as a traditional wideband device. C1 offers mono and stereo capabilities of the compressor and/or the gate. Now the C1 compressor and C1gate also offer 88.2/96kHz support.
