RDL TX-TPS1A Active Single-Pair Sender, Twisted Pair Format-A, Balanced Line Input

Bring clean, reliable audio to long-run security and surveillance installations with the Radio Design Labs TX-TPS1A Active Single-Pair Sender. This Audio Extender Transmitter accepts either a +4 dBu balanced input (detachable terminal block) or a -10 dBV unbalanced RCA source and delivers a buffered, studio-quality signal to a chosen Format-A twisted pair via RJ45. The front-panel switch lets you assign the signal to pair A, B or C, while LOOP IN and OUTPUT jacks allow daisy-chaining with other single- or two-pair senders for scalable multi-channel systems.

Designed for system integrators and AV professionals, the TX-TPS1A supports local or remote 24 Vdc powering so you can centralize power or feed modules through the twisted-pair cable—power status is confirmed by a front-panel LED. Whether you’re wiring surveillance audio, remote monitoring feeds, or distributed paging and broadcast links, the TX-TPS1A preserves signal fidelity and simplifies installation. Add this Radio Design Labs sender to your security, monitoring, or pro-audio toolkit to streamline twisted-pair audio distribution—order now or integrate it into your next surveillance/AV project.
