RDL DB-TPSL2A Series Two-Pair Active Audio Sender Module for RDL Format-A Twisted Pair Products, Black

Deliver clear, low-noise microphone and line audio to remote endpoints with the Radio Design Labs DB-TPSL2A two-pair active audio sender module. Designed for Format-A twisted pair systems, this faceplate module routes a studio-quality preamplified XLR mic (with 24 Vdc phantom and switch-selectable mic gain) to pair A while routing summed left/right RCA line inputs to pair B. That makes it ideal for security, surveillance and monitoring installations where reliable speech intelligibility and low distortion are required. The DB-TPSL2A supports remote powering through the same twisted pair cable or local 24 Vdc input via a detachable terminal block, and fused power pass-through feeds connected downstream modules. A front-panel LED provides quick confirmation of module power. With exceptional hum rejection and compact wall-box mounting, the unit reduces wiring complexity and accelerates deployment in access control, CCTV audio, paging and distributed audio projects. Add the DB-TPSL2A to your Format-A system to simplify remote audio distribution—perfect for security and pro-audio integrators looking for dependable, low-noise performance.
