Features and Specifications:
The BM-10 headset was designed to be a lightweight (only 3 oz), articulate sounding boomset that is ideal for DXpeditions, mobile, and general rag chewing.
The speakers used in the BM-10 are extremely sensitive and don’t require much AF drive from the transceiver. The frequency response is 60 Hz- 12 kHz with very low distortion. The ear pads are replaceable acoustic foam.
The BM-10 comes in two versions, a BM-10-Dynamic and a BM-10-iC (electret), to accommodate many radios on the market today.
The BM-10-Dynamic headset uses a dynamic element designed specifically for communications use. This 600 ohm dynamic element with work on most Amateur Radio rigs.
The BM-10-iC, using our iC electret element, was created for use on the Icom radios. Working with Icom America this element has been made to eliminate the low gain audio on some older and non-pro series radios. This element must be paired with the AD-1-IC (included) or AD-1-ICM adapter. The “iC” adapters have no internal d.c. blocking capacitor so power is passed allowing the iC electret element to operate. The iC element has an operating frequency response of 35Hz - 12kHz.
The microphone audio for the BM-10 series terminates into a 1/8” male plug while the head phone terminates into a 1/8“ stereo plug. (1/8” to 1/4” adapter included), and the in line PTT terminates in a 1/4” mono plug.
