The RDL FP-TPSR4A Format-A Two-Pair Audio Sender/Receiver 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 3W mono amplified fixed-level signal, usually from a commercial hospitality equipped TV. The FP-TPS4A unit 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 unit 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 excellent 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 a 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 Sender/Receiver is normally mounted behind a TV where AC power is available. A 24VDC power supply, available separately, provides power to the FP-TPSR4A unit and to the connected sending & 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 unit is receiving and distributing 24VDC to all the 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 Sender/Receiver is suited for guest room installations with bedside and restroom listening stations. The inputs and outputs are fully compatible with all RDL Format-A receivers. The unit features automatic fused power, hum rejection, low noise, and low distortion for designers and installers looking to work with twisted pair products.
