Heil Sound Pro-7-IC Blue Aviation Style Headset and Boom Microphone with Electret Microphone for Icom Radios

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

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 Heil Sound iC electret microphone 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 Pro 7 iC is supplied with our AD-l iC eight pin iCOM adapter cable. The iC adapters have no internal DC blocking capacitor so bias voltage can be passed allowing the iC electret element to operate.

All Pro 7 models includes the following accessories:

• Large PTT Switch.
• Military grade straight cable.
• Military grade coiled cable.
• Extra set of ear pads.
• Washable cotton ear pad covers.
