We have a Soundstructure C8 + C12 and have connected two Shure MX412 mics. The Shure MX412 has a toggle on/off button on the mic stand. It does not have any additional logic wires.
I am wondering if it is possible to use the Mute button in the Soundstructure Studio and cause the LED on the Shure MX412 to be off when the mic has been muted from the studio? I thought that turning off the channel the mic is connected to would achieve this, but can't see how this can be achieved from the studio.
