The BM-17-iC headset, using our iC electret element, was created for use with 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 or AD-1- iCM adapter. The iC adapters have no internal DC blocking capacitor so bias voltage can be passed allowing the iC electret element to operate. The iC element has an operating frequency response of 35Hz - 12kHz.
