RDL TX-TPS3A Active Three-Pair Sender, Twisted Pair Format-A, Balanced Line Inputs

Optimize multi-channel audio distribution for security and AV systems with the Radio Design Labs TX-TPS3A active three-pair sender. This audio extender transmitter converts three line-level sources into Format-A twisted-pair signals on a single RJ45 output, delivering studio-quality balanced circuitry for clear, low-noise sound across long cable runs. Each channel accepts either a -10 dBV unbalanced RCA or a +4 dBu balanced detachable terminal-block input, giving installers flexibility when connecting mixers, cameras, intercoms or recorders.

Power locally or remotely through the RJ45 jack to streamline installations and minimize rack clutter; local power also feeds downstream modules. The TX-TPS3A includes wiring-fault protection with an automatic reset fuse and a blue LED power indicator for dependable operation in 24/7 surveillance and monitoring environments. Compact and rugged, it fits neatly into pro accessory racks and equipment rooms.
