A close-talking unit, the SM12A may be used under noisy conditions without loss or masking of voice signals. The SM12A has two plugs on the end of the cable. 1/4" phone for the earphone and balanced XLR for the microphone.
The SM12A is a small, lightweight, rugged and reliable unit, with provisions for mounting to a supplied dual spring steel headband. A pivot housing permits the microphone boom to be moved 20 degrees in any direction, and the distance between the microphone and pivot to be changed by up to 89 mm (31/2 in.). The receiver ear tube, attached to the bottom of the pivot housing, may be moved through a 55 degree arc. A miniature windscreen to protect against wind noise and explosive breath sounds, and two connector belt clips are also supplied.
