The Quad Stereo Gate (QXG) is a four-channel stereo low pass gate and mixer. It features a brand new all-analog, vactrol-free circuit, designed after months of development to capture the character of classic vactrol-based LPGs while offering greater precision and reliability. With the Vactrol button, you can switch between: Slow Mode (ON): emulates the natural decay of a vactrol LPG. Fast Mode (OFF): delivers a precise, snappy response while retaining gentle filtering. Perfect for fast, complex modulation sources such as PoliMaths. Other features include: Stereo Sum Output with voltage-controllable Stereo Spread for wide spatial mixing. Individual Outputs that remove channels from the Sum when patched. Stereo Auxiliary In for chaining multiple QXGs into larger mixes. Pre-patch headers for seamless integration with PoliMaths and MultiMod. Chain two QXGs with a PoliMaths for immediate 8-channel amplitude control. Specifications: Width: 12HP Max Depth (incl. power cable): 43 mm Power: +12V 65 mA / -12V 75 mA Part of the New Universal Synthesizer System.
