  • Sennheiser MZA900 P Adapter by Sennheiser

Due to manufacturer's restrictions this item cannot be shipped outside of the United States.

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.

  • Input 3.5 mm stereo jack socket, lockable
  • Output XLR-3M

Guy says, "An absolute must for every Sennheiser Evolution G3 wireless owner. If you ever have multiple wireless hits, it may be time to go cabled. The MZA 900P allows you to use the stock Sennheiser ME2 mic via hardwired XLR. A total lifesaver! This also allows me to use my Sanken COS11-D lav which is wired for Sennheiser 3.5mm locking via XLR. Keep in mind that you still do need to enable phantom power."
