RDL D-TPR1A Active Single-Pair Receiver, Twisted Pair Format-A, XLR Microphone/Line Output

Deliver consistent, low-noise audio to multiple locations without running shielded cable. The Radio Design Labs D-TPR1A faceplate module is an active single-pair Format‑A twisted-pair receiver that converts one twisted-pair audio channel to a balanced XLR mic/line output, ideal for AV, security, surveillance and monitoring installations. Installers get flexible configuration on the rear panel: choose which of the three FORMAT‑A pairs feeds the output and set the XLR to MIC or LINE level. The module supports RJ45 pass-through so power and all three audio pairs continue to downstream receivers, enabling daisy-chaining and up to 10 bridged receivers per pair for distributed audio coverage. Power locally via the rear 24 Vdc terminal block or accept remote powering over the twisted pair; a front-panel LED confirms power status. Built to mount in Decora-style wall boxes or standard U.S. electrical boxes, the D-TPR1A simplifies system design, reduces wiring costs and delivers studio-quality balanced audio for professional monitoring and surveillance applications. Add this Radio Design Labs receiver to your next project for reliable, easy-to-install twisted-pair audio — contact sales or order today to streamline your deployment.
