This passive microphone switcher routes a dynamic mic between three outputs. With no footswitch pressed, the mic feeds Output A, while Outputs B and C are muted. Press Switch B or Switch C to mute Output A and route the mic to the selected transformer-isolated output. Releasing the switch automatically returns the microphone to Output A. Pressing B and C together routes the mic to both outputs simultaneously. 15 units was built for a local audio company.
