The Heil Pro Set is designed to meet the exacting standards of world-class Contest and DX operators. The Pro Set is lightweight, versatile headsets designed for comfort, durability, and, performance. The earpieces are full-sized, with heavily-padded cushions for operator comfort during long operating stints. The ear pad covers are removable for washing, and replacement pads are also available (see our Accessories and Parts page). The Pro Set features Heil Sound’s exclusive phase reversal technology, which allows the user to “move” the incoming signal by engaging the phase-reversal switch; this creates a unique spatial widening sound that can, in some situations, significantly improve copy in a tough DX pile-up.
he Pro Set 6 (PS 6) utilizes the HC-6 dynamic element designed for amateur radio use with most radio rigs including Kenwood and Yaesu. 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 speakers in the Pro Set series are 200-Ohm nominal devices, with a -3 dB point at 8000 Hz. This combination reduces hiss found in receiver audio stages. These speakers exhibit medium sensitivity but are easily driven by most rigs by turning the AF Gain control up to about 2 o’clock.
Each Pro Set is equipped with a windscreen for the microphone. The windscreen does not affect the frequency response of the microphone, and it is highly effective in minimizing breath blasts while you’re speaking.
