Heil Sound BM17DYN – AR Lightweight Dual-Sided Boomset W/Dynamic Element for Emergency Communications


The BM-17 is a lightweight dual-sided headset designed for Amateur Radio use. To accommodate different radio setups, the BM-17 is available with a BM-17-Dynamic Element.


The speakers used in the BM-17 are very sensitive and don’t require much AF gain from the transceiver. The frequency response is 200 Hz – 5 kHz with very low distortion. The ear pads are replaceable acoustic foam.

The BM-17-Dynamic headset uses the BM-D dynamic element designed specifically for communications use in Ham Radio. This 600 Ohm dynamic element will work on most amateur radio rigs requiring a Low-Z input impedance (usually between 150 Ohms and 4k Ohms). The BM-17-Dynamic has an operating frequency response of 120 Hz – 10 kHz.

The microphone audio for the BM-17 series terminates into a 1/8” mono plug while the headphone terminates into a 1/8“ stereo plug (1/8” to 1/4” adapter included).

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.

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 headset microphone while the 1/4” female that exits the adapter is the PTT (push to talk) line for the Heil foot switch or hand switch. The 1/8” or 1/4” stereo plug goes into the headphone jack on the transceiver front panel.
