RDL SF-TPR24A - 24-Channel Line-Level Receiver Module

The SF-TPR24A is an eight-section audio receiving chassis compatible with RDL Format-A twisted pair products. Each section receives up to three audio sources and provides three outputs corresponding to signal pairs A, B and C. A studio-quality buffer amplifier feeds +4 dBu balanced outputs through a detachable terminal block.

The SF-TPR24A features bridging inputs, allowing it to be connected to the LOOP OUT jack of other receivers. The bridging input circuits used in all FORMAT-A twisted pair receivers allow connection of up to 10 receiver outputs for each cable pair. The possibility of multiple receiver locations adds enormous flexibility in the design of audio routing systems using RDL FORMAT-A products.

The SF-TPR24A may be powered directly from a 24 Vdc power supply using either the power jack or the detachable terminal block. Local power connected to the module is also fed to all modules connected to the eight INPUT RJ45 jacks. Power for each RJ45 connector is protected against wiring faults by an automatically resetting fuse. Front-Panel green LEDs indicate valid module power on each RJ45.
