The RDL D-TPS1A is a professional single-pair audio sender designed for RDL Format-A twisted-pair audio distribution systems. It provides a convenient way to connect a balanced microphone to a Format-A system and send the audio signal over standard twisted-pair cabling.
Designed for commercial AV installations, the D-TPS1A combines a balanced XLR microphone input, built-in 24V phantom power, selectable microphone gain, and flexible RJ45 signal routing in a compact Decora-style module. Its installation-friendly design makes it suitable for classrooms, conference rooms, houses of worship, performance spaces, and other distributed audio applications.
The D-TPS1A can be installed in a wall box, equipment cabinet, or standard U.S. electrical box, giving system designers flexibility when locating microphone inputs throughout a facility.
The D-TPS1A is available in several finishes for different installation requirements:
-
D-TPS1A – White Decora-style finish
-
DB-TPS1A – Black Decora-style finish
-
DS-TPS1A – Stainless steel finish for demanding commercial and industrial environments
Professional Microphone Input
The D-TPS1A provides a balanced XLR microphone input that supports both dynamic and condenser microphones. Built-in 24V phantom power allows compatible condenser microphones to operate directly from the module without requiring a separate phantom power source.
A precision microphone preamplifier provides clean signal amplification with low noise and distortion. Installers can select between Normal and High gain settings to accommodate microphones with different output levels.
This makes the D-TPS1A useful for permanently installed microphones as well as presentation and paging applications.
Flexible Format-A Signal Routing
Once the microphone signal has been amplified, the D-TPS1A sends it to one of the three available Format-A audio pairs.
A rear-panel selector allows the installer to choose:
The module includes two RJ45 connections that allow power and audio signals to pass through the module, providing additional flexibility when expanding a Format-A installation.
Daisy-Chain Multiple Audio Sources
The D-TPS1A can be incorporated into larger Format-A systems using its pass-through RJ45 connections.
Depending on the system configuration, installers can:
-
Connect one Format-A audio pair
-
Daisy-chain up to two additional single-pair senders
-
Connect a compatible two-pair sender on pair A
-
Pass all three audio pairs and the power pair through the RJ45 connections
This allows multiple audio sources to share the same twisted-pair infrastructure without requiring a separate cable run for every sender.
Local or Remote Powering
The D-TPS1A provides flexible powering options for different installation designs.
The module can receive power locally through its 24 VDC terminal-block input, or it can be powered remotely through the twisted-pair network using a compatible Format-A device or RDL power inserter.
A blue front-panel LED provides a quick visual indication that the module is receiving power.
High-Quality Audio Transmission
The D-TPS1A uses active balanced circuitry designed to maintain clean audio transmission while helping minimize unwanted noise and interference.
Key performance benefits include:
-
Excellent hum rejection
-
Low-noise operation
-
Low-distortion audio
-
Balanced signal transmission
-
Automatic fused power protection
-
Reliable Format-A system integration
These characteristics make the D-TPS1A a practical choice when clean microphone audio needs to be distributed throughout a commercial facility.
Installation Flexibility
The compact Decora-style design allows the D-TPS1A to be installed in a variety of locations.
Common installation options include:
-
Wall boxes
-
Standard U.S. electrical boxes
-
Equipment cabinets
-
AV equipment locations
-
Conference rooms
-
Presentation areas
-
Paging stations
The available white, black, and stainless-steel finishes also make it easier to match the module to the surrounding installation.

Why Choose the RDL D-TPS1A?
The RDL D-TPS1A is a practical solution when a commercial audio system needs a microphone input located away from the main equipment rack. By combining microphone preamplification, phantom power, and Format-A twisted-pair transmission in a compact wall-mounted module, it simplifies the connection between local microphones and distributed audio equipment.
Its selectable gain and output-pair configuration also give installers flexibility when integrating the module into larger Format-A systems.
