Heil HM-12 Hand microphone

The Heil HM-12 microphone was specially developed for amateur radio. The high output, full frequency range, dynamic "Genesis" element is designed to work with almost all low impedance amateur radio transmitters. This element is mounted in a unique internal shock mount and features nearly -35 dB of backward rejection, reducing background and ambient noise from the transmitted signal.

The HM-12 exhibits a very natural frequency response and is designed so that the traditional Heil +4 dB peak is centered at 2 kHz. This attention to detail results in excellent voice articulation balanced with a clean, clear bass 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 routed to pins 1 and 2 of the 4-pin XLR connector. A CC-1-x-x cable is required for operation, see 'Accessories'.

The microphone has an internal foam windscreen and is supplied with a 5/8"-27 microphone clamp suitable for table stands, microphone boom, shock mount, etc.
The surface has a satin black finish.
