RDL TX-TPSA1A TX Series Three-Pair Combiner to Single-Pair Sender

The Radio Design Labs TX-TPSA1A three-pair combiner to single-pair sender streamlines multi-pair audio distribution for pro audio, security and surveillance systems. Designed to sum isolated signals from Format-A pairs A, B and C and drive them onto a single OUTPUT pair, the TX-TPSA1A reduces cable runs and simplifies infrastructure while maintaining audio integrity through precision active balanced circuitry. With a wide frequency response from 10 Hz to 50 kHz, the module preserves fidelity across voice and high-frequency monitoring needs. Installers gain flexibility with a front-panel selector to choose which pair is driven, RJ45 LOOP IN pass-through for daisy-chaining additional senders, and the ability to power modules via any RJ45 jack or an external 24 Vdc supply. Built-in protection includes an automatically resetting fuse and a front-panel LED that indicates valid power. Ideal for CCTV audio, access control paging, and distributed monitoring systems, the TX-TPSA1A offers a compact, reliable solution for integrating pro-audio into security and networked AV deployments.
