The D SERIES-TPSL2A 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.

APPLICATION: The -TPSL2A modules feature an XLR microphone input and two RCA phono jack inputs summed to

mono. The unbalanced inputs are designed to receive standard -10 dBV consumer level signals. The microphone input
provides 24 Vdc IEC phantom voltage and accepts both dynamic and condenser microphone signals. The input signals are
amplified using studio-quality preamplifiers optimized for normal operating levels. A rear-panel GAIN switch is provided to
set the amplification of the microphone preamplifier. This 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 pair A. The summed left and right line-level inputs are routed to output cable pair B.

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. One single-pair sender may be chained with the -TPSL2A. A single-pair sender must be set to
feed pair C if it is connected together with the -TPSL2A. The power pair and all three audio pairs are fed through both
rear-panel RJ45 jacks.

The -TPSL2A 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 -TPSL2A 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. The pre-amplified microphone source is routed to pair A. The summed left and right line-level inputs are routed to
output cable pair B. A single-pair sender must be set to feed pair C if it is connected together with the -TPSL2A.

STEP 2: 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 3: Connect the twisted pair cable(s) and fasten the module in its mounting box.
