The RS-100 was designed to interface with all Clear-Com Main Stations. It has a self-contained power amp that is currentlimiting and short circuit proof. The all steel case houses a potted P.C. board for maximum durability. The RS-100 power amp supplies enough volume (102 dB) for excellent clarity and intelligibility yet will not cause ear fatigue when used for extended periods. A stainless steel belt clip mounts the lightweight unit on belt or clothing.
