When set with the above controls the Compressor's number of bands and eventually the X-Over
frequencies, each compressor operating on each single band is a RMS Compressor working as
shown by the following picture
The RMS Compressor is a Compression process applied with fast slow Attack and Release times to
the INPUT signal of a Unit, in order to maintain the amplitude of the OUTPUT signal at a defined
level, when input level is exceeding a defined intervention Threshold.
The Compressors implemented in the CLP2600 are acting on the evaluation of an input signal
which is an averaged one on a 50ms time frame, and representing actually the RMS value of the
input signal itself, so to make more
Musical
the Compressors action.
The RMS Compressor, it is so maintaining constant the output energy and not the Output peak, so
to have for the different inputs, independently from their harmonic content, a constant output
RMS level.
More, for the CLP2600 Compressors is also available a Ratio and a Hard/Soft Knee parameters.
The Ratio parameter is allowing to get a compressed output maintaining a constant Db ratio with
the input.
This feature is got in the CLP2600 with a precise Look Up Table Log Computation process, allowing
int the ratio maintenance a precision of 0.1dBu.
The Hard and Soft knee feature is allowing the user to select between a sudden compression
intervention when the input signal it is just above the Threshold (Hard Knee) or a smoother one
starting the compression smoothly before the Threshold.,
