• PM Resonator - 3 Channel Formant Filter

The PM Resonator is a recreation of the formant filter section of a Polymoog™ synthesizer in a standard 5U double-width modular panel. Each of the three filter channels has a control for frequency, signal gain, and emphasis or resonance.

A rotary switch selects the type of filter mode for each of the three channels. The modes are low pass, bandpass, band notch, and high pass.

The MU version is housed in a 2MU (4.25 inch wide by 8.75 inch high) panel with DOTCOM compatible power connector.
