RDL SF-TPRS12A 4 3-pair audio sending sections and receiving sections

The SF-TPRS12A chasis transmits and receives up to 12 channels of RDL Format-A analog audio over standard twisted pair CATx cable for distribution across your facility. Four three-pair send sections accommodate 12 balanced or unbalanced input signals on terminal block connectors. The unit then distributes the audio via four three-pair RJ45 outputs to other RDL Format-A products (sold separately). The SF-TPRS12A also receives 12 channels of Format-A analog audio on RJ45 connectors for distribution to balanced or unbalanced line-level gear or other RDL Format-A products (all sold separately). Module power connections are available via a 24 Vdc power supply (sold separately) or a detachable terminal block. Any additional modules (sold separately) connected to the RJ45 jacks will also receive power, with each RJ45 connector being fault protected by auto-resetting fuses.
