DB-TPR1A

RDL DB-TPR1A – Active Single-Pair Format-A Receiver with XLR Output

RDL DB-TPR1A is a professional Format-A receiver module designed for wall-mount AV, commercial, and educational installations. It receives audio from one selected twisted pair (A, B, or C) and delivers it to a balanced XLR output, with switch-selectable mic or line level.

Rear-panel switches allow selection of the input pair and output level. The module features studio-grade active balanced circuitry for clean, reliable audio performance.

Two RJ45 jacks allow signal and power pass-through to additional Format-A receivers. Up to 10 receivers can be connected per cable pair. The module can be powered via the twisted pair cable or locally through a terminal block. An auto-resetting fuse protects the power circuit, and a front-panel LED indicates valid power.
