Description
The DCM-100 is a miniature, inductively-coupled wireless earphone utilising an advanced digital microelectronics platform running custom software. It produces outstanding speech quality, reduced interference levels, precise output level control and is anatomically profiled to fit deep into the ear canal making it discreet, secure and usable in the left or right ear. Special functions include hard-squelch, which fully mutes the earphone when no audio signal is present, automatic gain control and low battery alarm. The DCM-100 is robust and designed to operate in hostile environments and incorporates a hygienic user-replaceable cerumen (earwax) filter system. Design emphasis has been placed on its ability to suppress interference; typically generated by data systems in vehicles, TDMA noise from TETRA/P25 terminals and Cellphones as well as mains-borne noise from electric motors, neon signs and power lines. A full range of compatible neckloops, shoulder loops and brooch inductive transmitters is available to operate with the DCM-100 wireless earphone.
