The D SERIES-TPS1A modules are single-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 -TPS1A models mount in RDL WB-1U and WB-2U wall boxes, or
in standard U.S. electrical boxes. The D-TPS1A features a white front-panel laminate with gray lettering that matches RDL Decora©-style remote controls. The DB­TPS1A features a black front-panel laminate. The DS-TPS1A is constructed of stainless steel to coordinate with RDL Decora-style stainless steel remote controls in
commercial/industrial installations.

APPLICATION: The D SERIES-TPS1A modules feature an XLR microphone input. The module provides IEC 24 V phantom and

accepts input signals from both dynamic and condenser microphones. The input signal is amplified using a studio-quality
microphone preamplifier optimized for normal operating levels. The rear-panel GAIN switch is normally set by the installer for
NORM (normal) gain. If consistently low mic levels are expected, this switch may be set to the HIGH gain position.
The pre-amplified microphone source is routed to one output cable pair selected during installation using a rear-panel switch.

These modules drive only one cable pair, therefore they accept signals and power from other mic-level or line-level Format-A
senders. The D SERIES-TPS1A modules have a second RJ45 jack for these input cables. Two other single-pair senders may be
chained with the -TPS1A, or a single two-pair sender may be connected. If three single-pair senders are connected together, each
sender must feed a different pair: A, B or C. The -TPS1A must be set to feed pair A if it is connected together with an RDL
two-pair sender that feeds stereo audio on pairs B and C. The power pair and all three audio pairs are fed through both rear-panel
RJ45 jacks.

The D SERIES-TPS1A 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 -TPS1A 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: Set the MIC gain switch to NORM (normal gain) unless consistently low mic level signals are expected. Set the MIC gain switch to

HIGH if low levels are always expected. Note: If both normal and low level mic signals are expected, the gain should be set to NORM to avoid
clipping when high levels are connected.

STEP 2: Set the PAIR selector so the module is driving the desired pair A, B or C of the Format-A cable. If the module is connected together
with one or two other single-pair senders, each sender must be set to a different pair. If connected together with a two-pair sender, the switch
must be set to pair A.

STEP 3: 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 4: Connect the twisted pair cable(s) and fasten the module in its mounting box.
