What to do if the microphone indicator keeps blinking on Sony Control Unit?
- MMargaret DelgadoAug 25, 2025
If the microphone indicator and MIC ON/OFF button on your Sony Control Unit's chairman/delegate units are blinking, it could be due to several reasons: 1. Incompatible units are connected. If you are configuring a simultaneous conference system, make sure to use only SX-C700A/D700A/C750/D750 units. 2. Too many units are connected in series. Make sure that no more than 16 units are connected to one DELEGATE’S/CHAIRMAN’S connector. 3. A unit or connecting cable is defective. Try disconnecting the first blinking unit, replacing the connecting cable, or replacing the defective unit.
