BA-200 Audio Bridging Amplifier

 

CrosStar's BA-200 Bridging Amplifier is an audio bridging amplifier that interconnects multiple leased or customer owned telephone lines and radio circuits. The BA-200 isolates and interconnects five telephone lines together, with individual level controls for each line. Each individual telephone line port can be set up to operate with either four-wire or two-wire telephone lines. Two BA-200 may be interconnected to provide bridging for up to 10 telephone lines.

 

The BA-200 isolates lines and prevents impedance and level mismatches that cause SCADA data corruption. The BA-200 is suited for 300 or 1200BPS data and voice use. One line position has a standard Motorola 8 pin radio connector, for combining radio and phone systems.
