RDL DB-TPS1A Active Single-Pair Sender, Twisted Pair Format-A, XLR Microphone Input with Phantom

Bring professional microphone audio into your AV, security or surveillance system with the Radio Design Labs DB-TPS1A active single-pair sender. Built for Home AV receivers and low-voltage installations, this module accepts a balanced XLR microphone with phantom power and converts it to RDL Format‑A twisted pair for long-distance, low-noise transmission. Installers benefit from switch-selectable mic gain on the rear panel, selectable RJ45 pair routing (A, B or C), and remote powering over the same twisted pair — reducing cable runs and simplifying networked audio and monitoring setups. A blue LED clearly indicates module power, while the fused local power option and signal/power pass-through protect connected equipment and support daisy-chaining across multiple rooms or surveillance zones. The DB-TPS1A's Decora-style front plate matches standard AV receiver installs and commercial control panels for a clean, professional look. Ideal for conference rooms, integrated AV systems, or surveillance microphone feeds — add the DB-TPS1A to your next installation to streamline wiring and ensure studio-quality audio monitoring.
