Heil BM-17D-Dyn

The BM-17 is a lightweight headset designed for emergency communications. The speakers used in the BM-17 are very sensitive and don’t require much AF drive 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. This 500 ohm dynamic element will work on most amateur radio rigs requiring a Low-Z input impedance (usually between 150 ohms and 4k ohms). Radios requiring a high impedance input of 10k to 30k ohms will require the use of an XT-1 impedance matching transformer. The BM-17-Dynamic has an operating frequency response of 120Hz – 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).

The boom is designed to be extremely flexible and is swivel mounted to the headphone speaker for optimal positioning in any situation.

The use of the AD-1 series mic adapters allows simple interface with popular transceiver inputs. The adapter is 6-8” long and 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.

Some state laws prohibit the use of headsets while operating a vehicle. Please check with your local regulations and restrictions prior to usage of this product while operating
