The RDL D-TPS1A is a professional single-pair audio sender module designed for use with RDL Format-A twisted-pair audio systems. Ideal for commercial, industrial, and installed-audio environments, this module allows users to connect a microphone directly into any Format-A system using standard twisted-pair cabling.
Engineered for flexibility, D-TPS1A modules can be mounted in wall boxes, equipment cabinets, or standard U.S. electrical boxes, making them an excellent choice for AV integrators, contractors, and system designers. The module is available in multiple finish options:
-
D-TPS1A: White Decora-style front panel
-
DB-TPS1A: Black Decora-style front panel
-
DS-TPS1A: Stainless steel finish for rugged commercial/industrial environments, power, exceptional hum rejection, low noise, and low distortion provide designers and installers the optimum choice in economical twisted pair products.
Professional Microphone Input with Studio-Quality Performance
The D-TPS1A features a balanced XLR microphone input supporting both dynamic and condenser microphones, thanks to its built-in IEC 24 V phantom power. A precision, studio-grade microphone preamplifier ensures clean, low-noise operation and optimized gain structure.
A rear-panel GAIN switch allows installers to select NORMAL or HIGH gain, ensuring proper performance even with low-output microphones. Once amplified, the microphone signal is routed to the installer-selected cable pair (A, B, or C) via a rear-panel selector switch.
Flexible Signal Routing & Daisy-Chain Connectivity
Designed for maximum installation flexibility, the D-TPS1A:
-
Drives one Format-A audio pair
-
Provides pass-through power and audio on dual RJ45 jacks
-
Can be daisy-chained with up to two additional single-pair senders
-
Supports one two-pair sender when assigned to pair A
All three audio pairs and the power pair pass through both RJ45 connectors, allowing seamless expansion across distributed audio systems.
Local or Remote Power Options
The module can be powered in two ways:
-
Local 24 VDC Power Input (via terminal block), which also powers all connected modules
-
Remote powering through the twisted-pair network using any Format-A compatible device or RDL power inserter
A front-panel blue LED clearly indicates when the module is powered.
Superior Format-A Audio Performance
RDL Format-A products are widely known for exceptional audio quality and installation ease. The D-TPS1A delivers:
-
Excellent hum and noise rejection
-
Low-distortion audio transmission
-
Automatic fused power protection
-
Simple, reliable system integration
This makes it an ideal choice for classrooms, boardrooms, houses of worship, hospitals, performance venues, and any facility using long-distance twisted-pair audio distribution.
