4-Channel Signal Mixer & Utility Module At its core, the Instru crn is a four channel signal processing utility with distinct functionality and individual outputs per channel. It is optimised for both audio and control voltage signals and offers a voltage-controlled panner with constant power panning, a VCA, a ring modulator, and a signal crossfader all housed within a compact stereo mixer format. As a mixer, crn can function as a traditional end-of-chain summing stage with a built-in stereo VCA. It can also seamlessly expand to related stereo Instru modules via its pair of stereo back jacks and included low profile stereo cable. crn includes an optional stereo limiter that is perfect for everything between gentle signal softening to saturated drum bus distortion. Whether you need a feature-dense signal processor, a hyper-compact summing mixer, or a soft-clipping signal mangler, crn will meet the challenge.
