The FP-TPSR4A is part of the group of versatile FLAT-PAK products from Radio Design Labs. The unique FLAT-PAK case can be directly screwed or
bolted to cabinets or shelves. Optionally available rack-mounting accessories permit single or multiple FLAT-PAK module mounting.

APPLICATION:

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 superior audio performance that rivals or exceeds shielded wiring. Design simplicity, ease of installation,
unsurpassed flexibility, automatic fused power, exceptional hum rejection, low noise, and low distortion provide designers and
installers the optimum choice in economical twisted pair products.

The FP-TPSR4A is a sender and receiver that provides the interface between a hotel room television and
