The new Heil Pro Set Elite is the ultimate boomset designed for amateur radio operators and uses the Heil HC-6 wide response microphone element. 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’s 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. An 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.
The Pro Set iC (PS iC) utilizes the Heil Sound iC electret 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 PS iC is shipped with the AD-1 iC adapter cable. The iC adapters have no internal DC blocking capacitor so bias voltage can be passed allowing the iC electret element to operate.
