The Califone M319 Belt Pack Transmitter delivers handsfree wireless mic support to presentations. Since its frequencies work with all of the Califone PA equipment shown below, the M319 provides greater flexibility for matching the best PA to suit your needs. All that's needed is to turn on the power and set the channel on the M319 to match the receiving channel on the broadcasting PA.
The M319 has two power settings to tailor the output to the environment where the audio amplification is being used. The lower setting is for transmitting audio up to 50' within smaller, enclosed rooms. It's designed to help prevent interference if there are neighboring PA systems being used in the same building. The higher power level ensures your message will be heard in outdoor settings, gyms or auditoriums where the receiving PA is 50-150' from the M319.
The M319 can be used with any of the mics shown on this page. For use in outdoor settings, Califone recommends the Neck Mic (shown far right). Wrapping comfortably around the throat, the NM319 picks up sound vibrations from the vocal cords, eliminating disruptive wind noises or other factors which can adversely affect the quality of the audio.
