The D SERIES-TPS2A modules are two-pair audio sending 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 audio sources. The -TPS2A models mount in RDL WB-1U and WB-2U
wall boxes, or in standard U.S. electrical boxes. The D-TPS2A features a white front-panel laminate with gray lettering that matches RDL Decora©-style
remote controls. The DB-TPS2A features a black front-panel laminate. The DS-TPS2A is constructed of stainless steel to coordinate with RDL Decora­style stainless steel remote controls in commercial/industrial installations.

APPLICATION: The D SERIES-TPS2A modules feature two RCA phono jack inputs, one for the left channel source and
one for the right channel source. These inputs are designed to receive standard -10 dBV consumer level signals. The input
signals are amplified using studio-quality preamplifiers optimized for normal operating levels. The buffered left and right
inputs are routed to output cable pairs B and C.

These modules drive only two cable pairs, therefore they accept a signal and power from one mic-level or line-level
Format-A single-pair sender. The D SERIES-TPR1A modules have a second RJ45 jack for an input cable. One single-pair
sender may be chained with the -TPS2A. A single-pair sender must be set to feed pair A if it is connected together with the

-TPS2A. The power pair and all three audio pairs are fed through both rear-panel RJ45 jacks.

The D SERIES-TPS2A may be powered directly from a 24 Vdc power supply using the detachable terminal block. Local
power connected to the module is also fed to all connected remote modules. The -TPS2A 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.

Typical Performance reflects product at
publication time exclusive of EMC data, if any,
supplied with product. 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(s) and fasten the module in its mounting box.
