Description:

The Pro Micro is a lightweight single-side headset designed for Amateur Radio use. The Pro Micro is available with a iC electret element. The speakers used in the Pro Micro are very sensitive and don’t require much AF gain from the transceiver. The frequency response is 20 Hz – 17 kHz with very low distortion. The ear pads are replaceable acoustic foam. It contains the Heil iC electret microphone element. This element has been made to utilize bias power in iCOM radios which addresses low-gain issues that arise when using dynamic microphone elements. The -3dB points are fixed at 80 Hz and 12.5 kHz. The iC element requires +5 volts DC bias power, which all iCOM rigs provide. The microphone audio for the Pro Micro series terminates into a 1/8” male plug while the headphone terminates into a 1/8” stereo with an adaptor. To adjust the headset simply bend the stainless steel piece that is inside the black padded headband. All Heil Pro Micro headsets are shipped with foam windscreen that fits over the microphone. The windscreen does not change the frequency response and reduces the breath blasts directly into the microphone.
