RDL D-TPS1A Active Single-Pair Sender, Twisted Pair Format-A, XLR microphone input with Phantom

Optimize microphone feeds in security, surveillance and AV monitoring installations with the Radio Design Labs D-TPS1A active single-pair sender. This faceplate module accepts a balanced XLR microphone input with IEC 24 V phantom power and a studio-quality preamplifier, delivering consistent, low-noise performance for both condenser and dynamic microphones. Installers benefit from a rear-panel GAIN control and a switch-selectable output pair (A, B or C) so you can route audio exactly where it’s needed on Format-A twisted pair systems. Dual RJ45 jacks provide signal and 24 V power pass-through, enabling daisy-chaining and simplified cabling for paging, surveillance audio and monitoring networks. The Decora-style front plate (available in white, black or stainless steel) fits standard U.S. boxes for a clean, professional appearance in control rooms and secure facilities. Backed by RDL’s robust power-insertion and fused local power distribution, the D-TPS1A reduces installation time while improving audio reliability. Ideal for security, monitoring, and conferencing applications—specify the D-TPS1A to streamline microphone integration and order or contact your RDL dealer for pricing and deployment guidance.
