The Heil Sound Proset-6 is a lightweight, versatile boom mic/headset designed for comfort, durability, and, above all, performance. The earpieces are full sized, with heavily-stuffed cushions for
operator comfort during long operating stints. The ear pad covers are removable, for washing, and replacement pads are also available.
Besides sealing out noise passively, the Pro Set now includes 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.
Using a .82 inch diameter Mylar diaphragm, the - 3 dB points of the wide frequency range are set at 100 Hz and 12.5 kHz, with sensitivity of - 57 dB at 600 Ohms nominal output impedance centered at
1 kHz. The HC -6 audio response can be equalized to match just about any requirement.
