Class A custom VCA compressor design Derived from the legendary Red 3 Dual Compressor/Limiter, this custom VCA design results in superb sound and very low distortion. Legendary “Huge” feature with Bass expansion The bass expander circuit generates extra bass harmonics, fattening up low frequency signals. Add to this the single ‘Huge’ feature and be afraid, be very afraid! Super-quiet Optical Gate/Expander circuit The unique opto circuit featured in the ComPounder’s two Gate/Expander sections ensures quiet operation with no pops or clicks. High performance Optical limiter Improved performance over standard VCA limiter designs which tend to add high levels of distortion, even when they are not limiting. Full stereo linking capacity The link feature enables the ComPounder to act as a true stereo processor, enabling complete stereo control of every parameter.
