Analog Multimode Filter

Plum Audio ADVA 3U

Plum Audio's ADVA 3U is an analog filter module like no other, packing seven different filter modes, an internal white noise generator, and dual drive circuits in a mere 6hp. This compact design is all thanks to Plum Audio's custom ClickKnobs: concentric pots with push button functions for stacked parameterization. Across the top layer of controls, you'll find filter Cutoff and Resonance controls, plus a blend control for the internal white Noise generator. Meanwhile, the lower layer of controls set the Input and Output levels, plus the amount of modulation from the FM input (or white noise generator if no external source is connected). With the push buttons, you can enable either of the saturation circuits or scroll between the seven different filter modes. With all that's packed inside, Plum Audio's ADVA might be the most feature-packed compact filter ever conceived.
