The D-TPR1A Active Single Pair RJ45 Receiver Module from RDL is a single-pair audio receiving module compatible with RDL Format-A twisted pair products. The D-TPR1A features a white front-panel laminate with gray lettering that matches RDL Decora-style remote controls. This unit features an XLR output jack. A rear-panel switch set during installation determines which of the three Format-A pairs is buffered to feed the module output. The audio signal received from the selected pair of the RJ45 INPUT jack feeds the XLR audio output jack. The output level from the XLR jack is set to either MIC or LINE level during installation using a rear-panel switch.
This module receives signal from only one cable pair, so the D-TPR1A module has a second RJ45 jack to connect cables to additional receiver modules. Two other single-pair receivers may be chained to the second RJ45 jack, or a single two-pair receiver may be connected. In addition to completing the reception of signals from all three Format-A pairs, additional receivers may be connected to the same twisted pair feed. The bridging input circuits used in all Format-A twisted pair receivers allow connection of up to 10 receiver outputs for each cable pair. The power pair and all three audio pairs are fed through both rear-panel RJ45 jacks.
The D-TPR1A can be powered directly from a 24 VDC power supply using the rear-panel detachable terminal block. Local power connected to the module is also fed to all connected remote modules. The D-TPR1A may 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. This module is designed to be mounted in wall boxes, cabinets, or other enclosures that allow users to connect external equipment. The D-TPR1A unit can mount in RDL WB-1U and WB-2U wall boxes, or in standard U.S. electrical boxes.
