Voice Communication Microphone With Carbon Element
The Shure Specialty to General Communications Microphone Series 104 C designed for demanding outdoor and indoor communication systems — mobile and fixed station — including police, fire, utilities, forestry, mining, drilling, transportation, and industrial applications.

The 104C is a small, pressure–actuated, diaphragm–type, carbon microphone specially designed for clear, efficient speech reproduction. The 104C fits naturally and comfortably in the hand, and retains this feel in hot or cold weather. The sturdy, high–impact ARMO–DUR case is light and compact, and occupies minimal space in portable or mobile equipment. The 104C is equipped with a heavy-duty, push-to-talk switch and a long life, rubber-jacketed coil cord cable.

Note: The 104-C works only with an input designed for a carbon microphone. The 104C will not operate with public address or paging systems that require a dynamic mic element.
