Heil Sound Pro Micro Single Side Headset

The Pro Micro Single Side is a unique high performance single sided headset.

The Pro Micro 6 is outfitted with the HC-6 dynamic microphone element. Designed for Amateur Radio applications, the -3dB points are fixed at 100 Hz and 12 kHz with a sensitivity of -57 dB at 600 ohms output impedance (centered at 1 kHz.) Note: To use dynamic mic elements on vintage radios (requiring a high impedance input of 10k to 30k ohms) will require the use of an XT-1 impedance matching transformer.

The Pro Micro iC contains the Heil iC electret microphone element designed for use with ICOM radios. This element utilizes 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 adapter.

To adjust the headset simply bend the stainless steel piece that is inside the black padded headband.

The use of the AD-1 series mic adapters allow simple interface with popular transceiver inputs. The adapter is 6” long and has a 1/8” female input jack for the boomset microphone and a 1/4” female that is for the PTT (push to talk) line for the Heil foot switch or hand switch. The 1/4” stereo plug goes into the headphone jack on the transceiver front panel.

All Heil Pro Micro Boomsets are shipped with foam windscreen that fits over the microphone. The windscreen does not change the frequency response, just the breath blasts directly into the microphone.
