D SERIES-TPR3A Modules: Ideal for High-Quality Audio Reception
The D SERIES-TPR3A modules are three-pair audio receiving modules that are fully compatible with RDL Format-A twisted pair products. Designed for wall boxes, cabinets, or other types of enclosures, these modules allow users to connect external equipment with ease. The -TPR3A models can be mounted in RDL WB-1U and WB-2U wall boxes or standard US electrical boxes.

These modules are available in different colors, depending on the user's preference. The D-TPR3A features a white front-panel laminate with gray lettering to match RDL Decora-style remote controls. The DB-TPR3A has a black front-panel laminate, while the DS-TPR3A is constructed of stainless steel, making it perfect for commercial/industrial installations that use RDL Decora-style stainless steel remote controls.

The D SERIES-TPR3A modules feature an XLR audio output and two RCA phono jack outputs (one for the left channel and one for the right channel). The audio signal received from pair A of the RJ45 INPUT jack feeds the XLR audio output jack. During installation, the output level from the XLR jack can be set to either MIC or LINE level using a rear-panel switch. The audio signals received from pairs B and C of the twisted pair cable are buffered to drive the RCA output jacks at the standard -10 dBV consumer level.

Thanks to the bridging input circuits used in all FORMAT-A twisted pair receivers, additional receivers can be connected to the same twisted pair feed. This feature allows for enormous flexibility in the design of audio routing systems using RDL FORMAT-A products.

The D SERIES-TPR3A can be powered directly from a 24 Vdc power supply using the rear-panel detachable terminal block. Alternatively, the -TPR3A can be remotely powered through the twisted pair cable from any other module, signal distributor, or RDL power inserter connected to the same twisted pair cable. Module power is indicated by a front-panel LED.

In conclusion, the D SERIES-TPR3A modules provide designers and installers with an excellent choice in economical twisted pair products. With superior audio performance, design simplicity, ease of installation, unsurpassed flexibility, automatic fused power, exceptional hum rejection, low noise, and low distortion, these modules are the ideal solution for high-quality audio reception.
