Technical Data; Handling Precautions - Panasonic AJ-MC900G Operating Instructions Manual

Features
This super-directional electret stereo microphone has been developed to serve as the
front microphone for video cameras.
By setting its mono/stereo switch to MONO, it can also be used as a super-directional
monaural microphone.
The AJ-MC900G has a stabilized power supply circuit built into the grip and uses a DC
48 V capacitor microphone phantom power supply.

Handling precautions

Electret capacitor microphones are easily damaged by high temperatures and
humidity. Therefore, take care not to expose the microphone to water or to leave the
microphone for extended periods of time near strong lights, exposed to direct sunlight
during the summer, or in vehicles with the windows rolled up, etc.
Be sure to use an output cable with balaced connections.
Unbalanced cables (cables wihch short Pin 2, 3, 4 or 5 to Pin 1) cannot be used.
OSee the operating instructions of the camera recorder for a description of mounting
methods.
