MODEL SM14A
HEAD-WORN MICROPHONE WITH RECEIVERS
GENERAL
The Shure Model SM14A Professional Head-Worn Mi-
crophone with Receivers is a low-impedance, unidirec-
tional, dynamic microphone with two integral earphone
assemblies. Each receiver assembly has its own
transformer and phone plug for monitoring separate
sound sources. Designed for sports and news an-
nouncing, interviewing and intercommunication sys-
tems, and for special-events remote broadcasting, the
SM14A offers convenient, hands-free operation without
user fatigue. A close-talking microphone, the SM14A
may be used under noisy conditions without loss or
masking of voice signals. The SM14A is a small, light-
weight, rugged and reliable unit, with provisions for
mounting to a supplied cushioned headband. A pivot
housing permits the microphone boom to be moved
20° in any direction, and the distance between the
microphone and pivot to be changed by up to 89 mm
(3 ½ in.). The receiver ear tubes, attached to the bot-
toms of the pivot housings, may be moved through a
55° arc. A miniature windscreen to protect against
wind noise and explosive breath sounds, and three
connector belt clips are also supplied.

ASSEMBLY
Assemble the SM14A for use as follows:
1. Twist the lower headband arms 90° so they are
perpendicular to the headband. For left side usage,
the microphone retaining clip will be on the left side
of the user’s head; for right side usage, the
microphone clip will be on the right (see photo and
Figure 1).
2. Snap the microphone pivot housing into the
retaining clip with the pivot adjustment knob upward
and the microphone toward the front. Loosen the
pivot ad-justment knob, position the boom so that
the microphone is near where the side of the mouth
will be, and tighten the pivot adjustment knob.
3. Snap the pivot housing of the second receiver
assembly into the remaining retaining clip with the
receiver tip downward. Insert the receiver cable in the
groove across the top of the headband. In this way,
the two cables will be adjacent to each other.
4. Place the assembled microphone on the user’s head
and pull the headband arms downward until they
rest against the head just over the ears. Position the
receiver tips at the entrances to the ears. (Make
cer-tain cables are free of receiver ear tubes.)
