The TX-TPR6A 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-TPR6A permit permanent or removable mounting. The TX-TPR6A may be rack or surface mounted
with optional TX™ series accessories.

APPLICATION: The TX-TPR6A 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 feeds 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 bridging transformer provides isolation between the twisted pair cable and the audio output.

The TX-TPR6A is a single-pair receiver, bridging the input signal from the cable pair set on the front-panel
switch during installation. This module receives only one cable pair, therefore 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. All three audio
pairs are fed through from the INPUT jack to the LOOP OUT jack.

The TX-TPR6A is a passive module that does not require power to operate. Power present on a cable
connected to one RJ45 jack is passed through to the modules connected to the other RJ45 jack.

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.

Model TX-TPR6A
Format-A Single-Pair Receiver

STEP 1: Set the PAIR selector so the module is receiving signal from the desired pair A, B or C of the Format-A cable.
STEP 2: Connect the INPUT twisted pair cable coming from Format-A senders or distributors.
STEP 3: Connect either the UNBAL OUT jack (-10 dBV) or the BAL OUT (+4 dBu) terminals to a high-impedance equipment input.
STEP 4: Connect the LOOP OUT twisted pair cable feeding additional Format-A receiver(s), if any, and mount the module

.

Pair A: Audio +4 dBu

Pair B: Audio +4 dBu

Pair C: Audio +4 dBu

Pair D: Power +24 Vdc

RJ45 conductor colors shown are for 568A standard. The 568B standard may be used if the connectors at both ends of the cable are wired identically.
