Heil Sound PRO 7 BU – AR Industrial Headset with Dynamic Element with PTT (Blue)


The Heil Sound Pro 7 is an aviation-style headset designed for amateur radio use in high noise environments.


The specially designed foam-gel ear pads provide 26 dB outside noise reduction and provide exceptional comfort. A true dual channel, stereo headset, the Pro 7 Series feature an audio balance control which allows the user to adjust the level of the left earphone to match the right. A unique phase-reversal switch greatly helps the listener “dig out” weak signals. The latest version of the Pro 7 features a monitor jack. The latest version of the Pro 7 features a monitor jack which allows a second operator to plug in headphones and monitor audio.

The flexible gooseneck mic boom on Pro 7S may be rotated for use on either the right or left ear.

The low distortion Dynamic HC-7 microphone element exhibits a frequency response of 100 Hz – 12 kHz with the -3 dB points at 100 Hz and 12 kHz. The traditional Heil speech articulation rise is centred at 2k – 4 kHz with properly balanced highs and lows. The impedance is 600 Ohm. The HC-7 is one of our best microphone elements for speech articulation.

The balance control located on the left speaker controls the left speaker. To use, set a comfortable right side level with the AF gain of the receiver. You can then adjust the left side speaker where necessary to balance the audio between the speakers. In most cases, the balance control will be close to maximum.
