Passive LPG 1U

Intellijel

Simple, DC-coupled, vactrol-based, 1-pole passive low pass gate controlled by an external CV input. Passive module requiring no power.456

Capabilities 2

Lowpass Gatelowpass-gate
1-pole passive DC-coupled low pass gate using a vactrol. Gate fully opens at +5V CV; fully closed at 0V.456
Vactrol-basedvactrol
Uses a vactrol whose internal LED slowly dims when CV is removed, producing a natural decay characteristic suitable for struck-percussion sounds.456

Jacks 3 — 2 in / 1 out

NameSignalVoltageDescription
Inputs (2)
CV INcv0V to 5VCV input that controls the extent to which the Low Pass Gate affects the signal. At +5V, the gate fully opens. At 0V, the gate is fully closed. Includes a Level LED that dims as CV diminishes.456
LPG INaudio—Input into the Low Pass Gate circuitry. Any signal patched in will be gated by the voltage at CV IN and sent to LPG OUT.456
Outputs (1)
LPG OUTaudio—Output of the Low Pass Gate. Contains an amplitude- and timbre-modified version of the LPG IN signal, determined by the voltage at CV IN.456
