PNR Headset from Avcomm
Developed to meet the needs of both general aviators and helicopter
pilots, the AC-747 PNR is the single answer for both applications
in one headset!
who fly both general aviation and helicopters no longer need
to buy, carry, and store two different headsets or use clumsy
adapters. The AC-747 converts easily by plugging in either the
general aviation straight cord or the helicopter coil cord (both
included with the headset). An optional general aviation coil
cord is also available. If you break a cable, no problem. Simply
unplug and replace.
ultra-lite micro samarium cobalt speakers produce a richer,
smoother frequency response for both voice and music. The powerful
magnetic core and diaphragm provide high sensitivity and optimized
response. The speaker, a thin lightweight 4/10th's of an ounce,
reduces headset weight for added comfort. The advanced speaker
installation technique enhances audio performance, reduces annoying
inner ear cup vibrations and increases noise attenuation. Each
ear dome also features a fully adjustable volume control for
truly customized performance. Unique to the AC-747 PNR, each
speaker features a 2-pin connector, allowing easy removal to
change to 32 ohm speakers. This feature is an advantage to pilots
with hearing loss who require more volume.
flex boom bends and holds any position easily for precise microphone
placement. The M-60 microphone with ceramic hybrid active filtering
chip amplifies desired voice signals while eliminating up to
75% of unwanted background noise so that you can be heard more
clearly even in the noisiest of environments. Additionally,
the preamp circuit is immune to environmental changes, will
not corrode, and has a much longer life than conventional PCB
copper wire with spiral shielding eliminates RF interference
while a polyurethane cover adds abrasion resistance and flexibility.
Additional features include gold plated plugs, high impact ABS
ear cups, easy-to-adjust stainless steel headband with easy
thumbnut adjustment, deluxe comfort head pad, acoustic foam
ear seals, 100% cotton ear covers, acoustic mic muff to protect
against moisture and wind noise, plus a full five-year factory
