Pro7BK: 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 new technology to the headset industry. The 2\u2033 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\u2019s, 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 \u2013 useful for DXPeditions and contests as well as a stress reliever as your change the phase angle of the program source. A speaker balance control allows preferred level between the speakers.
\nThe PRO-7 has interchangeable microphone system allows the microphone element to be easily changed in the field for different types of applications. The low distortion Dynamic HC-7 element exhibits a frequency response of 100 Hz \u2013 12 kHz with the -3dB points at 100 Hz and 12 kHz. The traditional Heil speech articulation rise is centered at 2K-4KHz with properly balanced highs and lows. The impedance is 600 ohm. The HC-7 is one of our best microphone elements for speech articulation.<\/p>\n
Features:
\nThe most comfortable wearing headset – ever.
\nAdjustable stainless headband.
\nSpecial designed foam gel ear pads provide 26 dB PNR reduction of outside noise.
\nCotton cloth “booties” to cover the ear pads.
\n40 mil high response speakers producing extreme voice articulation.
\nAcoustically dampened speaker enclosure.
\n-3dB points set at 100Hz-12kHz.
\nSpeaker balance control adjusts level between the two speakers when you’re using a dual receiver, otherwise it will balance the sound from two speakers to one speaker.
\nFull Stereo, two channel reception, perfect for Dual Watch receiving systems.
\nMilitary spec cable system using 6 pin mini XLR and fiber reinforced cable.
