The MZA 900 P phantom power adaptor is used to connect pre-polarized condenser microphones with a 3.5mm jack plug to microphone inputs with 10 - 52 V phantom powering (P12 - P48). The connected microphone is supplied via the adaptor.

The phantom power adaptor is available in two different versions:

- MZA 900 P with lockable 3.5 mm jack socket (as evolution wireless)
- MZA 900 P-4 with lockable 3-pin special socket

The adaptor 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(-4) for wired applications (e.g. in the studio) or with a transmitter of the evolution series for wireless applications.

The MZA 900 P can also be used as a cable tester for XLR microphone cables.
