The TX-TPR1A is a single-pair audio receiving module compatible with RDL Format-A twisted pair
products. It is built in the versatile Max-TX series enclosure. The durable adhesives provided with the
TX-TPR1A permit permanent or removable mounting. The TX-TPR1A may be rack or surface mounted
with optional TX™ series accessories.
APPLICATION: The TX-TPR1A is a single-pair audio receiving module compatible with RDL Format-A
twisted pair products. A front-panel switch set during installation determines which of the three FORMAT-A
pairs is buffered to feed the module output. The audio signal received from the selected pair of the RJ45
INPUT jack feeds the -10 dBV unbalanced RCA phono jack output and the +4 dBu balanced detachable
terminal block output. A studio-quality buffer amplifier feeds the outputs at the correct operating level.
The TX-TPR1A is a single-pair receiver, bridging the input signal from the cable pair set on the front-panel
switch during installation. Because this module receives only one cable pair, a LOOP OUT RJ45 jack is
provided for connecting additional Format-A receivers. Two other single-pair receivers may be chained to
the LOOP OUT jack, or a single two-pair receiver may be connected. In addition to completing the
reception of signals from all three FORMAT-A pairs, additional receivers may be connected to the same
twisted pair feed. The bridging input circuits used in all FORMAT-A twisted pair receivers allow connection
of up to 10 receiver outputs for each cable pair. The possibility of multiple receiver locations adds
enormous flexibility in the design of audio routing systems using RDL FORMAT-A products. The power
pair and all three audio pairs are fed through from the INPUT jack to the LOOP OUT jack.
The TX-TPR1A may be powered directly from a 24 Vdc power supply using either the power jack or the
detachable terminal block. Local power connected to the module is also fed to all modules connected to
the INPUT and LOOP OUT RJ45 jacks. The TX-TPR1A may be remotely powered through the twisted pair
cable from any other module, signal distributor or RDL power inserter connected to the same twisted pair
cable. Module power is indicated by a front-panel LED.
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.
