ADDAC System ADDAC803 Quadraphonic Spatializer

The ADDAC803 Quadraphonic Spatializer injects immersive spatial audio into your Eurorack rig, using Vector-Base Amplitude Panning (VBAP) to position mono signals across a four-speaker field. Switch between Cartesian or Polar control schemes for intuitive sound movement, and tweak spatial behaviour in real time with onboard curve and offset controls. A fully analogue path powered by four precision VCAs ensures clarity, while dedicated CV outputs mirror panning and filtering movements—perfect for modulating effects based on spatial depth. With both 3.5mm and 1/4” outs and extensive CV I/O, the ADDAC803 is a serious spatial sculpting tool.
