| Heading: | Heil Sound HM12 Mic w/ 8 pin cable - NEW | 
| Ad Message: | Heil Sound presents the new HM-12 Mic. $104.99 Delivered - check, Zelle, PP FF Designed specifically for Amateur Radio communications. Their high output, full-range ‘Genesis’ dynamic elements are designed to work with just about every Amateur transceiver low impedance mic input. HM-12 elements are secured in a unique internal shock mount and exhibit nearly 35 dB of rear rejection to reduce background and ambient noise from the transmitted signal. Heil HM–12 Microphones exhibit 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 for producing high quality AM, FM or SSB signals. These microphones feature a ‘soft touch’ PTT switch, wired to pins 3 and 4 for transmitter control. Microphone audio signals are fed to pins 1 and 2 of the four-pin XLR. Heil HM -12 Microphones use the CC-1 series cables and feature an internal foam windscreen. Larry k6ro |
