The D SERIES-TPR2A modules are two-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 -TPR2A models mount in RDL WB-1U and WB-2U wall
boxes, or in standard U.S. electrical boxes. The D-TPR2A features a white front-panel laminate with gray lettering that matches RDL Decora©-style remote controls.
The DB-TPR2A features a black front-panel laminate. The DS-TPR2A is constructed of stainless steel to coordinate with RDL Decora-style stainless steel remote
controls in commercial/industrial installations.

APPLICATION: The D SERIES-TPR2A modules feature two RCA phono jack outputs, one for the left channel

output and one for the right channel. The audio signals received from pairs B and C of the twisted pair cable are
buffered to drive the output jacks at the standard -10 dBV consumer level.

This module receives signal from only two cable pairs, so the D SERIES-TPR2A modules have a second RJ45 jack
to connect cables to additional receiver modules. A separate single-pair receiver may be chained to the second
RJ45 jack. 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-TPR2A 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 -TPR2A
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: Connect the twisted pair cable coming from Format-A senders or distributors.

STEP 3: Connect the twisted pair cable feeding additional Format-A receiver(s), if any, and fasten the module in its mounting box.
