PRO 7ic

Heil Sound PRO 7ic has interchangeable microphone - Designed exclusively for iCOM radios

The Pro 7 offers a feature set that compliments the Heil Sound standard for headset design. Unlike copies of various aviation type headsets, the PRO 7 is not a copy. It brings newtechnology to the headset industry. The 2" thick gel foam ear pads provide extreme comfort for extended periods of time while exhibiting passive noise reduction rated at -26dB, ideal for use in high ambient noise environments. Using technology Bob Heil learned from Paul Klipsch back in the early 70's, the ear cup enclosures were tuned to the free air cone resonance of the speaker cone thus providing very low distortion with maximum voice articulation providing the ultimate sound reproduction for communications. The exclusive Heil Phase Reversal system (HPR) allows you to acoustically move the signals forward and creates a spatial widening of the sound field. This feature makes it easier to pull a weak signal from a pileup – useful for DxPeditions and contests as well as a stress reliever as you change the phase angle of the program source. A speaker balance control allows preferred level between the speakers.

Designed exclusively for iCOM radios, the iC Electret element has a -3dB fixed point at 35 Hz and 12kHz with the sensitivity of-48 at 1500 ohms output centered at 1kHz. The iC element solves the problems with LOW GAIN ICOM radios but can also work with great results on newer Icom models. Bias power is applied to operate the iC electret element. The Pro 7 iC is supplied with our ADl-iC eight pin iCOM adapter cable.
