The MZA 900 P phantom power adapter is used to connect pre-polarized condenser microphones with a 1/8" plug to microphone inputs with 10V- 52V phantom powering (P12 - P48). The connected microphone is supplied via the adapter. This version features a lockable 3-pin special socket.

The adapter is also a quick and flexible solution if a microphone is to be used for both wired and wireless applications. One and the same microphone can be used together with the MZA 900 P for wired applications (e.g. in the studio) or with a transmitter of the Evolution wireless series for wireless applications.
