Sennheiser MZA 900 P Phantom Power Adapter
The Sennheiser MZA 900 P lets a 3.5 mm locking lavalier, such as the ME 2 or ME 4, run on phantom power from the XLR mic input of a mixer, recorder, or camera.
It powers pre-polarized condenser mics from any phantom supply between 12 and 48 V, so one mic can go wired in the studio and wireless on an evolution wireless transmitter. A switch sets the gain to 0 or −12 dB, and the response runs from 20 Hz to 20 kHz. It also works as a tester for XLR mic cables.
Its lockable 3.5 mm socket matches evolution wireless bodypacks. For mics with Sennheiser’s 3-pin special connector, the MZA 900 P-4 is the version to choose.
