AI017 Low Pass Gate Black

Vactrol Based Low Pass Gate

The AI017 Low Pass Gate Eurorack Module can be used as a Voltage Controlled Filter, Voltage controlled Amplifier, or both. The AI017 is an updated variation of the classic Buchla 200 Series Low Pass Gate, updated with a tunable resonance circuit, and a Depth control. Vactrols are used for control voltage, allowing for classic "ringing" and "bongo" effects.

The Depth control compensates the vactrols inability to drop lower than 100 ohms, which can allow audio bleed on traditional Low Pass Gates. The effect can be switched on or off, as depth will attenuate the classic ringing and bongo effect. This gives the user an easy way to go from a "vintage" Low Pass Gate to a "modern" Low Pass Gate with a flick of the switch. A rear trimmer allows for the tuning of the resonance.
