The D-TPS1A Single Pair RJ45 Sender Module from RDL is a single-pair audio sending module compatible with RDL Format-A twisted pair products. The D-TPS1A features a white front-panel laminate with gray lettering that matches RDL Decora-style remote controls. The D-TPS1A module features 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 pre-amplifier optimized for normal operating levels. The rear-panel gain switch is normally set by the installer for Norm (normal) gain. If consistently low microphone 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.
This module drives only one cable pair, and therefore accepts signals and power from other mic-level or line-level Format-A senders. The D-TPS1A module has a second RJ45 jack for these input cables. Two other single-pair senders may be chained with the D-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 D-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-TPS1A can 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 D-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.
