The Electro-Voice ND86-RC3 is a robust, highperformance, dynamic supercardioid thread-on vocal
microphone head for wireless handheld transmitters.
This microphone head electrically and mechanically
adapts to Electro-Voice (and many other brands)
wireless handheld transmitters that use the common
3-contact rings, 1.25” diameter by 28-thread pitch
coupling convention. The floating captured ID collar
will spin freely until screwing the head on tightly. It
will remain locked in place when fully tightened. This
allows the desired orientation of the branding to the
transmitter.
Designed for excellent acoustic control in even the
largest of venues, the precisely tuned capsule delivers
present, smooth, and detailed sound, as well as
superior isolation from sound on the stage.
The microphone head's dynamic capsule contains a
large Mylar diaphragm, which delivers a rich and
detailed frequency response by combining its large
surface area for tonal balance with its low-mass highvelocity material for exceptionally fast transient
response.
The microphone head features an innovative capsule
shock-mount system consisting of a 4-point
suspension around the circumference of the capsule
combined with a tuned pneumatic pump at the
capsule base, offering superior handling noise
reduction to eliminate mechanical vibrations and noise
in the mix.
The Memraflex grille is made of a durable tight-mesh
grille wire that withstands extraordinarily rough
treatment. Your microphone head remains protected
and looking good gig-after-gig, year-after-year. For
additional protection, the capsule contains a
hydrophobic cloth membrane, which prevents
moisture and debris from reaching the diaphragm.
The capsule uses a humbucking coil that attenuates
AC hum and electromagnetic interference. Use the ND
dynamic mics with confidence near speaker cabinets
and EMF generating equipment racks.

Notice!
It is important to prevent under-driving or
over-driving the handheld transmitter input
stage. Pay special attention when matching
the transmitter input sensitivity to this micro-
phone head.
Adjust the transmitter sensitivity to a level
where the audio path meter on its companion
receiver shows 75%-95% full on high-empha-
sis vocal peaks for optimal signal strength
and quality.
