Heil Sound PSM6 – AR Pro-Micro Single-Sided Headset W/HC-6 Dynamic Element


The Pro-Micro is a lightweight single-side headset designed for Amateur Radio use. The Pro-Micro is available with a dynamic element.


The speakers used in the Pro-Micro are very sensitive and don’t require much AF gain from the transceiver. The frequency response is 20 Hz – 17 kHz with very low distortion. The ear pads are replaceable acoustic foam.

The Pro-Micro 6: The headset is outfitted with the HC-6 dynamic microphone element. Designed for Amateur Radio applications, the -3 dB points are fixed at 100 Hz and 12 kHz with a sensitivity of -57 dB at 600 Ohms output impedance (centred at 1 kHz).

The use of the AD-1 series mic adapters allows simple interface with popular transceiver inputs. The adapter cable has a 1/8” female input jack for the boomset microphone and a 1/4” female that is for the PTT (push to talk) line for the Heil foot switch or hand switch. The 1/4” stereo plug goes into the headphone jack on the transceiver front panel. To adjust the headset simply bend the stainless steel piece that is inside the black padded headband.

All Heil Pro-Micro Boomsets are shipped with foam windscreen that fits over the microphone. The windscreen does not change the frequency response, just the breath blasts directly into the microphone.

Note: To use dynamic mic elements on vintage radios (requiring a high impedance input of 10k to 30k Ohms) will require the use of an XT-1 impedance matching transformer.
