RDL D-TPS7A Passive Single-Pair Sender

Deliver clean, reliable audio over twisted-pair for security, surveillance and commercial AV applications with the Radio Design Labs D-TPS7A passive single-pair sender. This compact faceplate module accepts a stereo mini-jack source and uses a studio-quality transformer to provide galvanic isolation, eliminating hum and ground-loop problems when sending audio to remote monitoring stations. Because the D-TPS7A is passive and requires no power, it installs quickly and reduces points of failure in distributed audio networks.

Engineers and integrators benefit from the user-selectable RJ45 pair switch (A, B or C) to route the signal onto the correct Format-A cable pair, and the TP CABLE RJ45 pass-through makes daisy-chaining multiple senders straightforward. The module drives a single RJ45 pair, making it ideal for point-to-point audio feeds, paging tie-ins, and surveillance audio monitoring. Rugged, low-profile construction and US manufacturing ensure reliable performance in commercial and security environments.

Add the D-TPS7A to your next monitoring or AV deployment to simplify wiring, improve audio isolation, and streamline installations.

• Pass-through, passive design simplifies installation: no external power required so it integrates easily into existing security and AV deployments
• Studio-quality transformer provides galvanic isolation to reduce noise and ground-loop issues for clearer audio over twisted-pair
• Switchable RJ45 pair selection (A, B or C) gives flexible routing when distributing audio to monitoring, surveillance, or paging systems
• Stereo mini-jack accepts consumer line-level sources and combines to a mono feed, enabling quick connection of cameras, recorders, or media players
• TP CABLE RJ45 pass-through and daisy-chain support allow scalable multi-sender networks without extra wiring or complex configuration
