RDL SF-TPRS12A - Line-Level Sender/Receiver, 24-Channel, Format-A

RDL SF-TPRS12A is a professional multi-section line-level sender/receiver compatible with RDL Format-A devices, enabling simultaneous transmission and reception of up to 24 audio channels over twisted pair cabling. The unit features four sending sections and four receiving sections, each supporting three signal pairs (A, B, C) with +4dBu balanced inputs and outputs on detachable terminal blocks. Studio-quality active balanced circuitry ensures precise audio performance.

The sending sections allow connection of three line-level sources per section, transmitting them on the corresponding signal pairs in the twisted pair cable. Each RJ45 output feeds all three Format-A pairs, so no other sending modules may be connected on the same cable. The receiving sections support up to three signals per section and offer bridging inputs, allowing up to 10 receivers per cable pair.

Local power is supplied via terminal block or 24V DC jack, and all connected modules are powered through eight RJ45 connectors. Each section features a green LED indicating valid module power, and an automatic resetting fuse protects against wiring faults.
