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.

APPLICATION: The RU-TPDA is a four output signal and power distributor module compatible with RDL
Format-A twisted pair products. The INPUT RJ45 jack accepts a twisted pair cable originating from one or
multiple FORMAT-A senders. The LOOP OUT connector permits the input signal to daisy-chain to
additional distributor modules. The RU-TPDA input circuits bridge the cable pairs, allowing up to 10
distributors to be connected together to produce 40 distributed outputs. Further expansion is possible by
using one distributor output to drive up to an additional 10 distributors. Three RDL Dual-LED VU meters
are provided on the front panel of the RU-TPDA. One meter monitors the audio level on each of the three
FORMAT-A audio pairs.

The RU-TPDA is constructed in the durable MAX RACK-UP chassis which facilitates mounting three
distributors in a single rack unit. A wide variety of mounting accessories are available in the RDL
RACK-UP series. A power bus in each RU-TPDA allows power to enter one module at either side of the
rack. The included power jumper cable provides a simple method of interconnecting one distributor
module to the next, so multiple modules can be operated from a single power supply.

The RU-TPDA is powered directly from a 24 Vdc power supply using either one of the power jacks or the
detachable terminal block. Local power connected to the module is also fed to all modules connected to
the INPUT and OUTPUT RJ45 jacks. The power feeding each OUTPUT jack is separately protected by an
automatically resetting fuse. A power LED is associated with each OUTPUT jack, facilitating identification
of wiring faults. Module power is indicated by a front-panel LED.
