RDL SF-TPS24A 8 Twisted Pair Format-A Output Line-Level Sender

Overview of the RDL SF-TPS24A Eight-Section Audio Sending/Transmitter Chassis
The RDL SF-TPS24A is an audio sending/transmitter chassis that consists of eight sections. This product is designed to be compatible with RDL Format-A twisted pair products. Each section can connect up to three +4 dBu balanced line-level sources through a detachable terminal block. These signals are then transmitted via pairs A, B, and C of the associated RJ45 connector.

It's important to note that the SF-TPS24A feeds all three signal pairs in the twisted pair cable, and no other sending modules may be connected on the same cable with each RJ45 output.

This product can be powered directly through a 24 Vdc power supply using either the power jack or the detachable terminal block. Additionally, local power connected to the module is also fed to all modules that are connected to the eight OUTPUT RJ45 jacks. Each RJ45 connector power is protected against wiring faults by an automatically resetting fuse. The front-panel green LEDs indicate valid module power on each RJ45.
