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 is used with plug-in power. Battery installation: Unscrew the lower section of the microphone and slide it down to reveal the battery compartment. Insert the battery being certain to observe polarity as indicated (+ end toward the front of the microphone). Close and secure the cover. Remove the battery during long-term storage. Output for each stereo channel is low impedance (Lo-Z) unbalanced. The included 6' (1.8 m) shielded cable features a 3.5 mm stereo mini-plug at the output end. Locating the PRO 24 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.
