The D SERIES-TPR1A modules are single-pair audio receiving modules compatible with RDL Format-A twisted pair products. These modules are designed to be
mounted in wall boxes, cabinets or other enclosures that allow users to connect external equipment. The -TPR1A models mount in RDL WB-1U and WB-2U wall
boxes, or in standard U.S. electrical boxes. The D-TPR1A features a white front-panel laminate with gray lettering that matches RDL Decora©-style remote controls.
The DB-TPR1A features a black front-panel laminate. The DS-TPR1A is constructed of stainless steel to coordinate with RDL Decora-style stainless steel remote
controls in commercial/industrial installations.

APPLICATION: The D SERIES-TPR1A modules feature an XLR output jack. A rear-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 XLR audio output jack. The output level
from the XLR jack is set to either MIC or LINE level during installation using a rear-panel switch.

This module receives signal from only one cable pair, so the D SERIES-TPR1A modules have a second RJ45 jack
to connect cables to additional receiver modules. Two other single-pair receivers may be chained to the second
RJ45 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 both rear-panel
RJ45 jacks.

The D SERIES-TPR1A may be powered directly from a 24 Vdc power supply using the rear-panel detachable
terminal block. Local power connected to the module is also fed to all connected remote modules. The -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.

Installation/Operation

Declaration of Conformity available from rdlnet.com.

Sole EMC specifications provided on product package.

Specifications are subject to change without notice.

STEP 1: Connect 24 Vdc to the power input terminals if this module is not being powered through the twisted pair cable from another module, or if

this module is located an excessive distance from the next powered module on the cable. Note: The front-panel power LED will be illuminated if
this module is powered. If this module is powering other modules through the cable and if there is a wiring short, the short must be cleared then
power must be turned off to this module for 10 seconds to reset the internal protection circuit.

STEP 2: Set the PAIR selector so the module is receiving signal from the desired pair A, B or C of the Format-A cable.

STEP 3: Connect the twisted pair cable coming from Format-A senders or distributors.

STEP 4: Connect the twisted pair cable feeding additional Format-A receiver(s), if any, and fasten the module in its mounting box.
