Product Info

ADVA is a fat-sounding 24dB ANALOG MULTIMODE FILTER packed with features including a VCA, white noise generator, pre and post-distortions and a smart interface that makes it a versatile beast in a surprisingly small package.

With 7 filter modes, ADVA provides high richness and a wide variety of tones; it can filter gently like an LPG or it can be pushed up to the edges of hot acid tones.

Unlike many other multimode filters, a phase keeper ensures that ADVA never inverts the input’s phase in any of its filter modes.

Self-Oscillation is available for all modes, producing a range of waves from clean sine waves up to soft square waves when activating the post-distortion circuit. Together with V/OCT tracking, ADVA works brilliantly as an oscillator or as a percussive sound generator.

A resonance loudness compensation circuit ensures that ADVA does not compromise on volume when the resonance is increased.

An Internal analog white noise generator is the little bit of spice that can make the world of difference. Blend it together with the input signal by rotating the dedicated knob to add more richness to your sound and further emphasize cutoff movements, or use it as an FM source to achieve the different flavors of dirty tones.

ADVA is packed with two separate distortion circuits. First, the soft-clipping overdrive is located in the sound path after the white noise blend knob and the input gain knob, a circuit which can push the incoming signal to thicken any waveform. If you blend the input with the noise generator it can compress the noise and exaggerate it to achieve more aggressive levels.

The second (post) distortion is located after the VCA, just before the output. This is a more aggressive distortion and can be used for acid and other dirty hot tones.

Although the sound path is completely analog, ADVA has a digital support circuit that enables a smart routing system with the option to modulate filter modes via CV, and a very intuitive interface that includes 3 CLICKKNOBS and an RGB LED ring that provides visual feedback for whatever state the filter is in.
