I see the box is phantom powered, but how does it pass 48v to condenser mics? If so, can 48v be turned off for use with dynamic mics?
Asked by: Daniel
This unit is made to power the Sennheiser MAS-1 button pecifically, to bring power to it and make it programmable for On, On/Off, PTT, and PTM modes. The phantom power from the mixer would go to the connected condenser microphone in the chain and if you are using a dynamic microphone it will not be affected by the condenser power in the line.
