The Heil Sound Pro Set 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 (see the "Parts" page).

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.

The earphone speakers in the Pro Set Series are 200-Ohm devices, with a -3 dB point at 8000 Hz. This combination reduces a lot of the hiss found in receiver audio stages. These speakers exhibit medium sensitivity, but they are easily driven
by most rigs if you turn the AF Gain control up to about 2 o'clock.

The Pro Set 6 utilizes the HC-6 element. Designed for commercial broadcast applications, the -3dB points are fixed at 100Hz and 12kHz with sensitivity of -57dB at 600ê output impedance (centered at 1kHz.)

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 blast while you're speaking.
