The Telex BP-2002 is an ideal beltpack that keeps users connected and offers mobility as well as hands free convenience. The power circuitry has been redesigned and reinforced to improve overall performance. An RTS Standard Compressor Limiter has been added to improve audio performance. For a completely portable intercom system, directly connect your belt pack to the back of an intercom Power Supply or Master station. Alternately, passive wall connector plates can be permanently installed at strategic locations, and the beltpacks can then be connected to these using cables. The BP-2002 is Clear-Com? compatible.
