Active Single-Pair Sender, Twisted Pair Format-A with XLR Mic Input and Phantom Power, Black – RDL DB-TPS1A

RDL DB-TPS1A — Active Single-Pair Sender, Twisted Pair Format-A with XLR Mic Input and Phantom Power

The RDL DB-TPS1A is an active single-pair sender designed to translate a microphone-level XLR input into a Format-A twisted-pair audio signal for distribution over balanced cabling. Onboard phantom power supports condenser microphones, eliminating the need for separate local power supplies at the source. Its active circuitry conditions mic signals for reliable transmission when paired with compatible twisted-pair receivers, simplifying installations in commercial audio and paging systems. The compact, black enclosure fits neatly into racks or equipment boxes and eases integration into existing low-voltage wiring paths. By converting standard XLR microphone feeds to Format-A twisted-pair, the DB-TPS1A reduces labor and cabling complexity for long-run audio runs. This unit is suitable for field installers, OEM integrators, and MRO teams needing a dependable method to adapt mic sources to twisted-pair infrastructure.

Key Features:

• Active single-pair sender for Format-A twisted-pair audio systems
• XLR microphone input with onboard phantom power support
• Black enclosure for discreet installation
