Radio Design Labs' FP-TPSR4A is a sender and receiver that provides the interface between a hotel room television and listening stations and audio input panels.

The Sender Section is an RDL Format-A audio sender that accepts either a stereo line-level or 1 to 3 Watt mono amplified fixed-level signal, usually from a commercial hospitality equipped TV. The FP-TPS4A distributes the source signal to two Format-A RJ45 output jacks to feed multiple Format-A receivers.

The input accepts either an unbalanced stereo or an amplified mono input. The FP-TPSR4A sends the unbalanced Left and Right sources over balanced twisted-pair cables on pairs B and C. If a mono amplified signal is connected, the mono source is fed to both pairs B and C. Audio circuitry is active balanced for superior audio fidelity and low-noise performance.

The Receiver Section is an RDL Format-A receiver with an RJ45 input fed by sender modules such as the D-TPS8A stereo input panel for portable computer or media player. Audio signals received on pairs B and C are amplified to feed two stereo RCA connectors at a standard -10 dBV consumer level. One of these outputs connects to the TV AUX input, the other is available to feed the input of a stereo amplifier in the room.

The FP-TPSR4A is normally mounted behind a TV where AC power is available. A 24 Vdc power supply, available separately, provides power to the FP-TPSR4A and to the connected sending and receiving modules. It is not necessary to connect power supplies to the connected senders and receivers, facilitating installation. A front-panel blue LED is illuminated when the FP-TPSR4A is receiving and distributing 24 Vdc to all three RJ45 jacks. The distributed output DC voltage is short-circuit protected by an automatically resetting fuse. A power fault on either output jack causes the blue LED to extinguish.

The FP-TPSR4A is ideally suited to guest room installations with bedside and restroom listening stations. The inputs and outputs are fully compatible with all RDL Format-A receivers. RDL Format-A features design simplicity, ease of installation, flexibility, automatic fused power, exceptional hum rejection, low noise, and low distortion - to provide designers and installers the optimum choice in economical twisted pair products.
