RDL D-TPS6A Passive Single-Pair Sender

Deliver clean, reliable audio over twisted‑pair cabling without adding power or complexity. The Radio Design Labs D-TPS6A Passive Single-Pair Sender converts dual RCA consumer line‑level sources into a single, isolated signal for Format‑A (RJ45) twisted‑pair distribution. A studio‑quality transformer provides galvanic isolation to reduce ground‑loop hum and protect downstream gear, while the passive circuitry means no local power supply is required. Installers benefit from the front‑panel gold‑plated RCA inputs for easy connection of CD players, mixers or line outputs, and a rear-panel switch lets you select which cable pair (A, B or C) the module feeds. The TP CABLE RJ45 jack offers signal and power pass‑through so multiple single‑pair or two‑pair senders can be daisy‑chained for zoned audio, paging, security monitoring or surveillance applications. Compact and US‑made, the D-TPS6A is ideal for integrators who need a dependable, low‑maintenance audio sender for commercial AV, security, and monitoring systems. Add the D-TPS6A to your next installation to simplify audio distribution — order today or contact your RDL distributor.
