FAQ

Q: What modules can I use to do quadraphonic sound on a Eurorack modular synthesizer?
A: Several modules are designed for quadraphonic sound, such as Shakmat Aeolus Seeds, Intellijel Planar 2, Antimatter Audio v3kt, u-he CVilization, New System Instruments Quad Mid Side, Kilpatrick Audio Sextuple Quadraphonic Spatial Director, Koma Elektronik Poltergeist, and Mutable Instruments Frames. These modules allow you to place, move, and manipulate sounds in a four-speaker setup.

Q: How can I output quadraphonic sound to the Front of House (FoH) mixer?
A: Using a pair of Intellijel stereo output modules with TRS balanced outputs and Intellijel headphones modules that can be interlinked. This way, you can have four TRS outputs that go to the FoH mixer and two stereo headphones outputs that go to a Zoom recorder. The TRS balanced outputs are very handy as they will cancel any noise that could be picked up by the cables.

Q: What is the difference between polar and cartesian modes for quadraphonic sound?
A: The polar mode uses angle and distance parameters to locate the sound in the quadraphonic space, while cartesian mode uses x and y coordinates. Some modules, such as Shakmat Aeolus Seeds, can switch between these modes and offer different ways of controlling the sound position with CV inputs and LFOs.
