The -TPS7A is a single-pair audio sending module compatible with RDL® Format-A twisted pair products. The front panel
features a single stereo mini-jack intended for stereo consumer line level audio sources. A studio-quality transformer
provides isolation between the audio source and the RJ45 TP CABLE.

D-TPP7A

The -TPS7A is a single-pair sender, feeding the input signal to the cable pair set on the rear-panel
switch during installation. This module drives only one cable pair, therefore a TP CABLE RJ45 jack is
provided to accept signals and power from other mic-level or line-level Format-A senders. Two other
single-pair senders may be chained to a TP CABLE jack, 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 -TPS7A 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 -TPS7A is a passive module that does not require power to operate. If power is present on a
cable connected to a TP CABLE jack, that power is passed through to the modules connected to the
other TP CABLE jack.

The D-TPP7A is the same as the D-TPS7A but includes a connection for composite video pass through.

Specifications are subject to change without notice.

Model DS-TPS7A & DS-TPP7A
Format-A Passive Single-Pair Sender

STEP 1: 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 2: Connect a high-impedance unbalanced audio source to the input (-10 dBu 3.5 mm mini-jack).

STEP 3: Connect the twisted pair cable(s) and mount the module.

RJ45 Standard wiring

Pair A: Audio +4 dBu

Pair B: Audio +4 dBu

Pair C: Audio +4 dBu

Pair D: Power +24 Vdc

RJ45 conductor colors shown are for 568A standard. The 568B standard may be used if the connectors at both ends of the cable are wired identically.

TYPICAL PERFORMANCE

Input: 3.5mm mini-jack, unbalanced stereo combined to mono
Input Level: -10 dBV, +22 dBu max
