One of the most versatile Eurorack VCF´s with sixteen different filter types

This multimode filter and VCA offers sixteen different filter types, each with two different resonance models, giving an incredible thirty-two different resonant filters to choose from. Also included are manual and CV control of filter type selection, along with 16 LEDs to give a clear visual indication of which filter type is currently selected.

The filter core circuitry is based on that of the rare and highly sought after Oberheim Matrix 12 synthesizer and has an all-analogue signal path. The Matrix 12 VCF originally offered fifteen filter types, however we have expanded this to 16 with the addition of AP4, a full four pole all pass phaser mode.

AJH added a unique P-Vox resonance distortion and overdrive circuit that changes the character of the resonance completely and can force all the filter modes into self-oscillation. This effectively doubles the filter variants and hugely broadens what is already a very impressive sound pallet.

Other features include an inbuilt VCA with Input and Output Level controls, a Peak level LED, CV control of resonance, and of course the legendary AJH-Synth build quality.
