The FP-TPS4A 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: The FP-TPS4A 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 output jacks to feed multiple Format-A receivers.

The input accepts either an unbalanced stereo or an amplified mono input. The FP-TPS4A 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 FP-TPS4A is normally mounted behind a TV where AC power is available. A 24 Vdc power supply, available
separately, provides power to the FP-TPS4A and to the connected receiving modules. It is not necessary to connect
power supplies to the connected receivers, facilitating installation. A front-panel blue LED is illuminated when the
FP-TPS4A is receiving and distributing 24 Vdc to both 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-TPS4A is ideally suited to guest room installations with bedside and restroom listening stations. The 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.
