NADY
HM-1
Headmic™
With the HM-1, singers/musicians,
DJ’s, Aerobic instructors, TV broadcasters,
and others who require the highest quali-
ty vocals with improved gain before feed-
back can achieve better performance
than is available with small omnidirec-
tional lapel microphones or even full-
sized stand-mounted cardioid micro-
phones. With its high sensitivity and wide
band width, the HM-1 is optimally
designed for both singing and speaking
applications. The close-up unidirectional
vocal pickup provides a full sound while
suppressing irritating background noises.
FEATURES
The HM-1 features an adjustable
gooseneck which can be set at any angle
required by the user. The head worn sup-
port system is extremely light and com-
fortable, and is designed to be visually
unobtrusive while worn. Its ear rests and
temple provide maximum stability during
use, even while moving, dancing, or shak-
ing the head. The durable cable assembly
and internal construction are designed to
minimize handling noise from contact and
movement.
The HM-1 is Nady's newest head-
worn mic and it incorporates state-of-the-
art technology for the best frequency and
transient response available. The
advanced design offers improved reliabil-
ity under adverse operating conditions
and negligible distortion as compared to
other head worn mics. The result is
remarkably stable performance.
The HM-1 is designed to operate either
with hardwired or wireless microphone
transmitters. And unlike condenser mics
used on many other headworn mics, the
dynamic mic on the HM-1 requires no
draining phantom power or troublesome
batteries.
USE & CARE
The head band's shaped rests are
placed on top of each ear and the rest of
the band extends around the back of the
head.The the pad supporting the goose-
neck rests on the temple in front of the
ear providing the necessary stability dur-
ing use. The temple pad can be adjusted
forward or back as necessary for a per-
fect fit for anyone. The flexible mic
boom descends from the ear on the left
side.
The entire HM-1 assembly has been
moisture-proofed to guard against deteri-
oration during use. After use in a high
moisture application such as aerobics or
a stage performance, remove the foam
screen, wipe off the headset with a
towel, and permit it to air-dry. Do not
store the unit in a closed space (e.g., a
plastic bag) until all moisture has evapo-
rated, and avoid conditions of extremely
high humidity. This will help maintain the
HM-1’s excellent performance. While the
HM-1 is not unusually sensitive to the out-
side environment, extremes in tempera-
ture can be harmful. Therefore, for exam-
ple, avoid leaving the microphone in
direct sunlight for long periods of time.

The HM-1 is a miniature cardioid polar pattern headworn dynamic micro-
phone, specifically designed to provide enhanced professional quality
vocal pick-up in applications for which hands-free operation is required.
With the introduction of the original Headmic™ over 15 years ago,
Nady pioneered the first headworn mics on the market. Now, Nady sets
the latest performance standard for headset mics with the new Nady
HM-1 Headmic™.
