The CLP160 is a Stereo RMS Compressor with the addition of a Sub Harmonic
Synthes izer. With reference to the following RMS Co mpres sion p rocess
representation

The CLP160 is implementing a REAL RMS Compressor, so compressing at the
same threshold a pure sinusoidal signal as a squared wave.
Particularly, 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 Compressor implemented in the CLP160 is 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 CLP160 Compressor 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 CLP160 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.,

In addition to the RMS Compression process, in the CLP160 is also available a
powerful Sub Harmonic synthesizer.

The Sub Harmonic Synthesizer is working generating sub Harmonics on the base
on the Harmonic content of the original signal.
Particularly, the amplitude distribution of the generated Sub Harmonics is
following the shape of a band pass filter set on the low part of the band.
The peak of this “band pass” filter, is centered on 65Hz.
This means that the Sub Harmonics added to the original sound, and being at
one octave below the harmonics detected in the original signal itself, will bring
a “deep” and very low extra body to the original sound.

The CLP160 has a bypass control in the analog domain.
