Noise Engineering’s Quantus Ampla is a compact, four-channel VCA. Not your average VCA, the Quantus Ampla features a bit of NE flair and can be used for tons of applications. From the top, each channel has two independent modes: amplify, which gives users normal VCA response, and attenuate, which makes the VCAs close instead of open in response to positive CV. The CV inputs are circularly normalled, so players can easily create effects over multiple voices, volume fades and transitions — all with minimal patching.
