SM10A
 | The Shure SM10A is a
low-impedance, unidirectional dynamic microphone designed for
close-talk head-worn applications such as remote-site sports
broadcasting and corporate intercom systems. It is also ideal for
singing drummers, keyboard artists, and other performers who need a
head-worn vocal microphone with superior noise rejection and a
smooth, natural-sounding frequency response

| Features |  
| The SM10A is very lightweight
and is typically mounted on the supplied steel headband assembly.
An adjustable pivot on the headband assembly allows the microphone
boom to be moved 20 degrees in any direction. The boom also slides
out so the microphone can be positioned up to 89 mm (3 1/2 in.)
from the pivot housing. A supplied windscreen reduces wind noise
and explosive breath sounds. Other features: 
Close-talk design provides
excellent isolation and minimizes
gain-before-feedbackExtremely rugged with fully
adjustable headband and microphone boomUnidirectional(cardioid) polar
pattern for superior rejection of unwanted soundA clip that fits over the XLR
connector and attaches to the user's belt or waistband, providing
cable strain relief |
