The QUAD SWITCH MATRIX ROUTER is a passive module, where 2 x 4 output jacks (“destinations“) can be routed in pairs to 2 x 4 signal inputs (“sources“) using four 6-way rotary switches with two “off “-positions.
This simple device is intended as a companion module to the M552, but suitable for a multitude of applications, where audio- and control-signals have to be routed fast and with immediate visual feedback.
