Heil PRO SET Elite IC Headset for Icom Ham Radio Transceivers, The new Heil Pro Set Elite is the ultimate boom set designed for amateur radio operators and uses the Heil HC-6 wide response microphone element. The HC-6 is designed for full-range audio or can be adjusted (with radio adjustment) for bright, articulate audio to cut through amateur radio noise and signal pileups. The Pro Set Elite offers dual-side, highly efficient speakers mounted in acoustically tuned chambers which offer high rejection of outside noise.
The exclusive Heil Phase Reversal feature allows the user to move the signal acoustically, which creates a spatial widening of the sound field that makes it easier to ‘see’ a signal inside a pileup while removing listener fatigue during prolonged use. The headphone speakers fold up for easy storage. The field-replaceable cushioned ear pads also come with removable cotton covers that can be easily removed for washing. The 6′ coiled cable terminates in a 1/8″ mono plug for the microphone, and a stereo 1/8″ plug for headphone speaker connection. A 1/8″ to 1/4″ adapter is also supplied.
The Pro Set Elite works with all Heil AD-1 adapter cables, which mate with just about every type of amateur radio transceiver. To find out which AD-1 adapter will work with your radio please consult the Heil Sound Adapter Selector. There are two different models: Pro Set Elite – 6 contains the Heil HC-6 full-range dynamic microphone element. Its -3dB points are fixed at 100 Hz and 12.5 kHz, with a sensitivity of -57 dB at 600 ohms output impedance (centered at 1kHz). The HC-6 response can be equalized to match just about any requirement, from full-range rag chew to serious contesting and DXing. Pro Set Elite – iC 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 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 -3dB points are fixed at 80 Hz and 12.5 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. Some state laws prohibit the use of headsets while operating a vehicle. Please check with your local regulations and restrictions prior to usage of this product while operating a vehicle.

Includes 8 Pin round connector for IC-7300, IC-7410, IC7600, IC756Pro series, and MANY others alike, if you are unsure just ask.
