Active Three-Pair Twisted-Pair Audio Sender, Format-A, XLR and Stereo Phono Inputs – RDL D-TPS3A

RDL D-TPS3A — Active Three-Pair Twisted-Pair Audio Sender, Format-A

The RDL D-TPS3A is an active three-pair sender designed to place microphone and stereo phono audio onto Format-A twisted-pair wiring. The unit accepts an XLR microphone input and dedicated stereo phono inputs to provide a straightforward interface between source equipment and twisted-pair distribution systems. As an active sender, it conditions signals for transmission across three cable pairs, simplifying multi-channel routing over a single multi-pair run. The D-TPS3A reduces cable complexity in installations that must carry microphone and stereo line-level sources without multiple parallel runs. Its compact form and direct-connect inputs make it well suited for retrofit projects, fixed installations, and equipment racks. The device is intended for professional use where twisted-pair audio distribution is required and where reliable, repeatable connectivity matters for system uptime and maintenance.
