The Burk TS-1 provides transient voltage surge suppression for equipment connected to a dial telephone line with standard RJ-13 or RJ-11 connectors. The high quality die cast aluminum enclosure houses a passive, three-stage protection device designed to conduct destructive energy safely to ground. Both RJ connections are protected, while allowing the normal ring voltage and voice or data to pass unimpeded.
The TS-1 can also protect studio or transmitter audio equipment connected to a two-pair dedicated stereo telco circuit.
