RDL DS-TPSML1A – Active Single-Pair Sender – Format-A – XLR Mic/Line Input

RDL DS-TPSML1A is an active twisted pair sender module designed for transmitting microphone or line-level signals in Format-A systems. Featuring a balanced female XLR input, it supports dynamic and condenser microphones (with P24 phantom power) as well as line-level sources. The studio-grade preamp ensures low noise, high fidelity, and excellent RF rejection.

The rear panel allows selection of gain mode (MIC HIGH, MIC LOW, LINE) and phantom power activation. The output signal is routed to one of three RJ45 pairs (A, B, or C), enabling flexible chaining with other Format-A senders. Power can be supplied locally via terminal block or remotely through twisted pair cabling. A blue LED in the XLR jack indicates active power status.
