C1-SIGMA is a stripped-down version of the C1-L1 VINTAGE COMPRESSOR

C1-Sigma is stereo and mono audio signal dynamic range compressor. C1-Sigma compressor has distinctive sound allowing its usage not only for technical purpose of dynamic range compression but also for artistic sound coloration. C1-Sigma compressor besides main dynamic range compression module also contains limiting module, which allows controlling peaks passing through the compressor, also supports «parallel» compression and M/S operational mode.

Product details

When control signal reaches threshold the compressor C1-SIGMA starts gain reduction very slowly thus most attack of the signal passes through (effect transient shaping). The curve of signal level change in this mode is similar to σ-function and due to that this attack mode is also called «sigmoid». C1-Sigma compressor is not an emulation of any hardware or software compressor. But due to their the sigmoid attack mode of audible results can be compared with the compressor Neve 33609 (on drum buss).
