DUAL LPG + MIXER + PRE-AMP

Inspired by the input / output section of the 208 music easel... This module features two independent vactrol based low-pass gates with CV input attenuation, offset, and LPG/Both/VCA Mode switches. Dedicated banana outputs of the LPG's, but also sent to a summing mixer which outputs to an 1/8" (3.5mm) jack.
The module also features a pre-amplifier for boosting signals from say.. a Piezo pickup to modular levels and outputs through a banana jack. The pre-amp is always providing gain from 5-30x amplification.

** 4U Modular is a term used for the format most commonly known as “Serge Format” or “Loudest Warning Format”. Out of respect for the ever growing format, 4U Modular is the easiest way to refer to it. More Specifically it refers to the panel height and mounting hole style. 4U Modular will patch up just fine with other 4U "Serge" formats such as "Random Source", but it will not mount in RS boats or Buchla Boats (or power off Buchla power for that matter). An info page about this will be added to the website soon to make this a lot more easy to understand.
