The Marani CLP-160 Stereo RMS Compressor with Sub-Harmonic Synthesizer utilizes a real RMS compressor that compresses a pure sinusoidal signal at the same threshold as a squared wave. The compression process is carried out 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 acts on the evaluation of an input signal which is an averaged one on a 50 ms time frame, and represents the actual RMS value of the input signal itself, so as to make the compressors action more musical.
The RMS Compressor maintains constant output energy for different inputs, independent of their harmonic content; maintaining a constant output RMS level. This compressor offers ratio and hard / soft knee parameters. The ratio parameter allows you to get a compressed output, maintaining a constant dB ratio with the input. With a precise look up table log computation process, this ratio parameter feature allows in the ratio maintenance with a precision of 0.1 dBu.
The hard and soft knee feature allows you to select between a sudden compression intervention when the input signal is just above the threshold (hard knee) or a smoother one starts the compression smoothly before the threshold. This compressor comes with a powerful sub-harmonic synthesizer that generates sub-harmonics based on the harmonic content of the original signal.
The amplitude distribution of the generated sub-harmonics follows the shape of a band-pass filter set on the lower part of the band. The peak of this band-pass filter is centered on 65 Hz. 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 low extra body to the original sound.
