The boom is designed to be extremely flexible and is swivel mounted to the headphone speaker for optimal positioning in any situation. RNEVER apply AC to the DC13.8V jack on the transceiver rear panel. mono plug while the headphone terminates into a 1/8in. The microphone audio for the BM-17 series terminates into a 1/8 in. The iC element has an operating frequency response of 35Hz – 12kHz. The iC adapters have no internal DC blocking capacitor so bias voltage can be passed allowing the iC electret element to operate. This element must be paired with the AD-1-iC (included) or AD-1- iCM adapter. Working with Icom America, this element has been made to eliminate the low gain audio on some older and non-pro series radios. R NEVER apply more than 16 V DC, such as a 24 V battery, to the DC13.8V socket on the transceiver rear panel. R NEVER apply AC to the DC13.8V socket on the transceiver rear panel. This may result in an electric shock or burn. The BM-17-iC Headsets, using the Heil Sound iC electret element, was created for use with Icom radios. RWARNING HIGH VOLTAGE NEVER attach an antenna or internal antenna connector during transmission. The BM-17-Dynamic has an operating frequency response of 120Hz – 10 kHz. Radios requiring a high impedance input of 10k to 30k ohms will require the use of an XT-1 impedance matching transformer. 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). The BM-17-Dynamic headsets uses the BM-D dynamic element designed specifically for communications use. The ear pads are replaceable acoustic foam. The frequency response is 200 Hz – 5 kHz with very low distortion. The speakers used in the BM-17 are very sensitive and don't require much AF drive from the transceiver. The BM-17 Headset series is available in FOUR different specialized versions to accommodate different radio setups and operator preferences:īM-17D-DYN Dynamic Mic Dual-Side HeadphonesīM-17D-iC Electret Mic Dual-Side HeadphonesīM-17S-DYN Dynamic Mic Single-Side HeadphoneīM-17S-iC Electret Mic Single-Side Headphoneįrom the four different listings below, order the version that matches your radio and listening preferences. has two small jumpers that can be set to enable Power and Speaker Audio.
