Lilt GB-CPX Studio Optical Compressor

This GB-CPX is a professional studio compressor in compact pedal format. It takes an instrument such as an electric guitar or bass guitar. Amplifies & compresses it and restores average volume after compression.

The PhotoOptical compressor is what gives GB-CPX unique character. It makes an instrument sound denser and playing seem more even for “produced” results.

Features:

SLOPE
Sets the average compression ratio applied to signals above threshold. Lower settings(anti-clockwise)have less effect. Turning the control clockwise increases the ratio and makes the effects of compression more dramatic. 

COMPRESS 
Sets the level of signal (or threshold) above which the signal starts to be compressed. Turning the compression control clockwise lowers the compression threshold, and drives the compressor harder. 

ATTACK
Sets how quickly the compressor reacts to peaks above threshold. Turn this control anticlockwise for a quick response. Slower(clockwise) allows the fast leading edge of percussive sounds to pass uncompressed for a moment. This example of “changing the enevlop”of a sound makes instruments sound more percussive. 

RELEASE
Sets how long the compressor goes on squashing the sound for, once the signal has dropped below threshold. If it stopped instantly there would be very noticeable modulation or ”pumping” of the sound. 

GR
The GR led is the compression indicator light, its brightness is related to the level of compression.
