The white D-TPS8A Active Two-Pair Sender from RDL is a two-pair audio sending module compatible with RDL Format-A twisted pair products. This module is designed to be mounted in wall boxes, cabinets, or other enclosures that allow users to connect audio sources. It features a white front-panel laminate with gray lettering that matches RDL Decora-style remote controls.

The D-TPS8A module features a stereo mini-jack input on the front panel. The input is designed to receive standard -10 dBV consumer-level signals from sources such as a computer or personal media player. The input signals are amplified using studio-quality preamplifiers optimized for normal operating levels. The buffered left and right inputs are routed to output cable pairs B and C.

This module drives only two cable pairs and therefore it accepts signals and power from one mic-level or line-level Format-A single-pair sender. One single-pair sender may be chained with the module. A single-pair sender must be set to feed pair A if it is connected together with the D-TPS8A Sender.

The D-TPS8A module has a Format-A input on the rear panel. This RJ45 input receives left and right signals from preceding senders and sums them together with the local mini-jack input. This allows multiple D-TPS8A modules to be connected in series with all the mini-jack inputs remaining active.

The D-TPS8A Sender is remotely powered through the twisted pair cable from any other module, signal distributor, or RDL power inserter connected to the same twisted pair cable. There are no illuminated indicators that could be distracting in dark locations, such as a hotel room. The unit features automatic fused power, hum rejection, low noise, and low distortion for designers and installers looking to work with twisted pair products.
