RDL TX-TPR2A Active Two-Pair Receiver

RDL TX-TPR2A Active Two-Pair Receiver

The TX-TPR2A is a two-pair audio receiving module compatiblewith RDL Format-A twisted pair products. Two outputs are provided correspondingto the two signal pairs B and C. The audio signal received on each pair of theRJ45 INPUT jack feeds the corresponding -10 dBV unbalanced output and the +4dBu balanced output on the detachable terminal block. A studio-quality bufferamplifier feeds the outputs at the correct operating level.

The TX-TPR2A features bridging inputs, allowing it to beconnected to the LOOP OUT jack of other receivers. The bridging input circuitsused in all FORMAT-A twisted pair receivers allow connection of up to 10receiver outputs for each cable pair. The possibility of multiple receiverlocations adds enormous flexibility in the design of audio routing systems usingRDL FORMAT-A products.

The TX-TPR2A may be powered directly from a 24 Vdc powersupply. Local power connected to the module is also fed to all modulesconnected to the INPUT RJ45 jack. The TX-TPR2A may be remotely powered throughthe twisted pair cable from any other module, signal distributor or RDL powerinserter connected to the same twisted pair cable. Module power is indicated bya front-panel LED.
