RDL DB-TPSL1A Active Single-Pair Sender, Twisted Pair Format-A - Mini-Jack and Stereo RCA In

Deliver dependable, low-noise audio from wall-mounted sources to centralized equipment racks with the Radio Design Labs DB-TPSL1A Active Single-Pair Sender. This Pro Wall Plates module accepts stereo sources via dual RCA or a mini-jack and combines them to a precision mono output that travels cleanly over Format-A twisted pair. A front-panel switch lets installers choose which RJ45 pair (A, B or C) carries the signal, simplifying wiring for security, surveillance and monitoring systems. Remote powering over the TP cable or a fused local power input ensures continuous operation, while a blue LED provides quick visual confirmation of power status. The DB-TPSL1A supports daisy-chaining with single- or two-pair Format-A senders, making it easy to expand or reconfigure audio distribution without additional converters. Engineered with studio-quality active balanced circuitry, it minimizes hum and interference on long cable runs—critical for mission-critical monitoring and AV installations. Ideal for integrators and IT teams deploying networked audio in control rooms, retail surveillance, or corporate conferencing. Add the DB-TPSL1A to your next installation to simplify audio routing and improve overall system reliability.

• Simplifies integration: accepts stereo input (dual RCA or 3.5mm mini-jack) and converts to a single, studio-quality mono send over Format-A twisted pair for clean audio distribution
• Flexible routing: front-panel switch selects which RJ45 pair (A, B or C) carries the audio, enabling quick configuration for security and surveillance deployments
• Remote-powered and daisy-chainable: receive power through the twisted pair or use local fused power for reliable operation across multiple senders
• Hardened, pro-grade circuitry: active balanced design preserves audio fidelity and reduces noise on long runs—ideal for monitoring and AV systems
• Compact wall-mount form factor: mounts in standard wall boxes or enclosures for neat installation in control rooms, security desks, or conference environments
