The DS-TPS3A Triple Pair RJ45 Sender Module from RDL is a three-pair audio sending module compatible with RDL Format-A twisted pair products. The DS-TPS3A is constructed of stainless steel to coordinate with RDL Decora-style stainless steel remote controls in commercial/industrial installations. This module features an XLR microphone input and two RCA phono jack inputs, one for the left channel source and one for the right channel source. 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 pre-amplifiers optimized for normal operating levels. A rear-panel GAIN switch is provided to set the amplification of the microphone pre-amplifier. This 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 pair A. The buffered left and right line-level inputs are routed to output cable pairs B and C.
The DS-TPS3A 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 DS-TPS3A 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. This unit is designed to be mounted in wall boxes, cabinets or other enclosures that allow users to connect audio sources. The DS-TPS3A model can mount in RDL WB-1U and WB-2U wall boxes, or in standard U.S. electrical boxes.
This module drives all three FORMAT-A cable pairs, so it is not equipped to receive inputs from other sender modules. The D SERIES-TPS3A may not be connected together with any other sending modules.
