The D SERIES-TPSL1A 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.

APPLICATION: The –TPSL1A modules feature a stereo line input through a mini jack or two RCA phono jacks summed

to mono. The unbalanced inputs are designed to receive standard -10 dBV consumer level signals. These modules drive
only one cable pair, therefore they accept signals and power from other mic-level or line-level Format-A senders. Two other
single-pair senders may be chained with the -TPSL1A, 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 power pair and all three audio pairs
are fed through both rear-panel RJ45 jacks.

The -TPSL1A 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 -TPSL1A 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: Set the pair selection switch to pair A, B or C to select the pair that will be driven. If three single-pair senders are connected together, each sender must feed
a different pair: A, B or C.

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.

Pair A: Audio +4 dBu

Pair B: Audio +4 dBu

Pair C: Audio +4 dBu

Pair D: Power +24 Vdc
