MODEL SM10A
UNIDIRECTIONAL HEAD-WORN MICROPHONE
The Shure Model SM10A Professional headworn Micro-
phone is a low-impedance, unidirectional, dynamic
microphone. Designed for sports and news announcing, in-
terviewing and intercommunication systems, and for
special-events remote broadcasting, the SM10A offers con-
venient, hands-free operation without user fatigue. Drum-
mers, keyboard artists and other musicians who need a
vocal microphone — one that will not pick up unwanted
sounds — will find the SM10A’s smooth, natural voice
frequency response and noise cancellation ideal for their
applications. A close-talking unit, the SM10A may be used
under noisy conditions without loss or masking of voice
signals. The SM10A is a small, lightweight, rugged and reli-
able unit, with provisions for mounting to a supplied dual
spring-steel headband. A pivot housing permits the micro-
phone boom to be moved 20
_
in any direction, and the dis-
tance between the microphone and pivot to be changed by
up to 89 mm (3
1
/
2
in.). A miniature windscreen to protect
against wind noise and explosive breath sounds, and a con-
nector belt clip are also supplied. An adapter plate for boom-
mounting on stereo headphones is available without charge.

ASSEMBLY
Assemble the SM10A for use as follows:
1.
Twist the lower headband arms 90
_
so they are perpen-
dicular to the headband. As supplied, the retaining clip
is positioned for left side operation as shown in Figure
1. For right side usage (see photo), remove the retaining
clip and attach it to the other (unused) hole in the head-
band arm so the screw is at the top.
2.
Snap the microphone pivot housing into the retaining
clip with the pivot adjustment knob upward and the mi-
crophone toward the front. Loosen the pivot adjustment
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.
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.
4.
Loosen the pivot adjustment knob and position the mi-
crophone as close as possible to the corner of the
mouth. For optimum close-talking operation, the micro-
phone should be less than 25 mm (1 in.) from the corner
of the mouth. Be sure to position the microphone at the
corner (not the center) of the mouth to eliminate explo-
sive breath sounds (“pop”). Tighten the adjustment
knob.
5.
Snap the connector belt clip over the groove in the 3-pin
audio connector. The clip can now be fastened to the
user’s belt or other clothing. Attach the 3-pin audio con-
nector to the microphone cable.
