The Clear-Com RS-100A is a portable remote intercom station, housed in a 16-gauge, stainless-steel case that provides strength and durability. The unit attaches to your belt with a sturdy stainless-steel clip. The RS-l00A contains a headset amplifier that provides sufficient output to drive one Clear-Com headset to a level greater than 110 dB SPL with no distortion. It can drive two headsets if connected with a suitable IIY"-cord. Because of the Station's low current draw and high bridging impedance, as many as 100 units may be connected in one system, over distances of up to one mile. A Visual Call Signal is standard on Clear-Com equipment and allows the user to visually attract the attention of operators who have removed their headsets. The RS-l00A also provides a unique sidetone adjustment, which allows the user to vary the level of his/her voice as heard in his/her headset. This control need only be set once, even if other stations subsequently join or leave the intercom network.
