Audio pre amp with envelope follower.

Instrument Interface is an eurorack pre-amp capable to bring any type of audio signal to modular levels thanks to its amplification circuit.
The module can drive regular and condenser microphones (+48V Phantom Powered) as well as Instrument and Line signals with a very low distortion ratio.
Going further from the regular re-amp operation, Instrument Interface offers some additional extra functions like a Trig/Gate extractor and Envelope Follower circuits, allowing you to use the character of your audio signal in more creative ways
