Active Three-Pair Twisted-Pair Sender with XLR Mic and Stereo Phono Inputs, Black – RDL DB-TPS3A

RDL DB-TPS3A — Active Three-Pair Twisted-Pair Sender with XLR Mic and Stereo Phono Inputs

The RDL DB-TPS3A is an active three-pair twisted-pair sender that converts XLR microphone and stereo phono sources into the Format-A twisted-pair audio format for distribution over three-pair cable. Its active design enables reliable transmission of multiple audio channels on a single three-pair run, simplifying installations that would otherwise require multiple dedicated audio cables. The DB-TPS3A addresses common wiring challenges in commercial AV deployments by consolidating mic and stereo sources for remote reception at a Format-A compatible receiver. This compact, format-specific sender is suitable for use where space and cable economy are priorities, and it supports straightforward integration into existing twisted-pair infrastructure. Field installers and low-voltage technicians will appreciate the simplified wiring and reduced cable bulk. OEM customers can integrate the unit into systems requiring remote audio links, while MRO operations can deploy it to replace or upgrade legacy point-to-point audio connections.
