1. DESCRIPTION / OVERVIEW:
The SB4001 is a Quad VCA based compressor, and can be used for either stereo or
mono applications. The VCA is used for the gain reduction and is a very accurate and
powerful design, perfect for a number of signal types and musical applications. VCA’s
have historically been used in a large number of classic compressors. While the
SB4001 is not directly based off of any of these classic compressors the nature of the
VCA lends itself to share some of the sonic characteristics. We have taken these sonic
qualities and have done our best to improve and augment them by carefully tuning our
circuit and features to take full advantage of what can be done with these VCA’s. We
hope you enjoy it as much as we do.
