From the project

A collection of Avalon Harmonics branded synthesizer modules.

MiniDJ is a compact fully analog module that houses a stereo crossfader with an adjustable volume curve, as well as a DJ style filter, both adjustable with CV. The module is compact at only 6hp and very shallow, making it an easy install in various travel and performance cases. Features a golden (ENIG coated) panel.

The module has two sets of stereo inputs, which correspond to channels A and B, as well as a stereo output. The two channels are mixed together through the crossfader, and are then passed into the DJ style filter before leaving the module.
