microphone input and an accessory shoe. The microphone is designed for
either battery operation or for battery-free operation when used with
camcorders (or other recording devices) that provide plug-in power (2-10
volts DC) at the mic input. If used without plug-in power, install the battery
before attempting use. If used with a recording device equipped for plug-in
power, simply plug the microphone cable's stereo mini-plug directly into the
recording device's microphone input. No battery is needed when the
PRO 24-CM is used with plug-in power.

Output for each stereo channel is low impedance (Lo-Z) unbalanced. The

Locating the PRO 24-CM nearer the sound source enhances the width of
the stereo image, while decreasing room ambience. Conversely, as the mic
position moves away from the sound source, a narrower left/right stereo
image results, and more of the “room sound” is noted.

Avoid leaving the microphone in the open sun or in areas where temperatures
exceed 110° F (43° C) for extended periods. Extremely high humidity should
also be avoided.
