Heil Sound HM-12 Single Element Communications Microphone with PTT
The new HM-12 microphone is designed specifically for amateur radio communications. The high output full range ‘Genesis’ dynamic element is designed to work with just about every amateur radio low impedance transmitter. The element is mounted in a unique internal shock mount and exhibits nearly -35 dB of rear rejection, which reduces background and ambient noise from the transmitted signal. The Heil HM-12 exhibits a very natural audio response from 80Hz - 14 kHz. The traditional Heil +4 dB peak centered at 2 kHz gives the new HM-12 excellent voice articulation balanced with clean, clear low-end response producing a high quality AM, FM or SSB signal. The ‘soft touch’ PTT switch is wired to pins 3 and 4 for transmitter control with the microphone signal fed to pins 1 and 2 of the four-pin XLR. The Heil HM -12 uses the HEIL CC-1 Connecting Cables.
