The -TPA1A is part of the group of versatile wall-mounted products from Radio Design Labs. The standard mounting case can be directly fastened in North American
electrical boxes or in RDL International wall boxes.

APPLICATION: The –TPA1A modules are two-pair audio amplifier modules compatible with RDL Format-A twisted pair products.
Each –TPA1A receives stereo audio and 24 Vdc power through a rear-panel RJ45 jack. The left and right audio signals received
on pairs B and C of the twisted pair cable are summed to mono and amplified. The amplified output level is set by an internal VCA
which is controlled by a front-panel volume control. The VCA attenuator provides years of scratch-free gain adjustment.
The –TPA1A circuits are all designed for low power consumption. Amplification is provided by a high-efficiency Class D powerstage with audio filtering tailored for crisp, pleasant audio clarity. The high-efficiency Class D output stage produces negligible heat
for all levels of expected voice or music modulation. When the user reduces the audio level to minimum, the class D output stage
is switched off. This sleep mode remains active until the user turns up the output level.
The output drives either a 4 Ohm or 8 Ohm speaker. The speaker cable connects to the module using a detachable terminal
block.
The front panel does not include any illuminated indicators, making the –TPA1A ideally suited to installation in dark rooms orareas. Installation is simple and quick, requiring only the connection of the speaker leads and the twisted pair RJ45.
The –TPA1A may be fed and powered from any RDL Format-A sender, and is ideal in hospitality installations fed from a senderconnected to a TV monitor (for example: FP-TPS4A Audio Sender from TV with fixed audio output level).
Use the –TPA1A wherever a single speaker user-adjustable wall mounted amplifier is needed. Combine the amplifier with other
RDL Format-A products for a cost-effective, high-performance audio system.

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 screwedor 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 andlow-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 theFP-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, easeof 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 TP-HA1A is part of the group of versatile Twisted Pair products from Radio Design Labs. The unique case can be directly screwed or bolted tocabinets, shelves or furniture.

APPLICATION: The TP-HA1A is a two-pair receiver and audio headphone amplifier compatible with RDL Format-A
twisted pair products. Each TP-HA1A receives stereo audio and 24 Vdc power through a rear-panel RJ45 jack fed
from a Format-A sender. The left and right audio signals received on pairs B and C of the twisted pair cable areamplified and fed to the left and right channels of the output 3.5 mm Mini-jack.
The front panel provides the headphone output jack and a single-turn user volume control. There are no illuminatedindicators that could be distracting in dark locations, such as a hotel room. The audio input circuits feature very highcommon mode rejection and a high quality stereo headphone amplifier for superior audio fidelity and low-noiseperformance.
The TP-HA1A is ideally suited to guest room installations with bedside and restroom listening stations. The input isfully compatible with all RDL Format-A senders.
The TP-HA1A is equipped with two Format-A RJ45 jacks. Either jack may be used as the input. The other RJ45
may be used to connect an additional TP-HA1A or other Format-A receiver.
Installation is simple and economical. Standard twisted pair cable is used to connect a Format-A sender to theTP-HA1A. The base plate of the TP-HA1A has cutouts that allow installers to pre-wire the twisted pair cable withRJ45 connectors attached. The finished twisted pair cable/connector can be fed through the base plate prior tomounting. The base plate is mounted with two screws, the twisted pair cable is plugged in, then the cover plate is
attached with one screw.
RDL FORMAT-A features superior audio performance that rivals or exceeds shielded wiring. Design simplicity, easeof 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.
