Radio Design Labs DB-TPS2AM Active Two-Pair Sender - Twisted Pair Format-A-XLR microphone & stereo Mini-jack in

The D SERIES-TPS2AM modules are two-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. The -TPS2AM models mount in RDL WB-1U and WB-2U wall boxes, or in standard U.S. electrical boxes. The D-TPS2AM features a white front-panel laminate with gray lettering that matches RDL Decora-style remote controls. The DB-TPS2AM features a black front-panel laminate. The DS-TPS2AM is constructed of stainless steel to coordinate with RDL Decora-style stainless steel remote controls in commercial/industrial installations. APPLICATION: The D SERIES-TPS2AM modules features an XLR microphone input and a stereo Mini-jack input summed to mono. The unbalanced Mini-jack 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 preamplifiers optimized for normal operating levels. A rear-panel GAIN switch is provided to set the amplification of the microphone preamplifier. This switch is normally set by the installer for NORM (normal) ga" If consistently low mic 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 Mini-jack input is routed to output cable pair B. , These modules drive only two cable pairs, therefore they accept a signal and power from one mic-level or line-level Format-A single-pair sender. The -TPS2AM modules have a second RJ45 jack for an input cable. One single-pair sender may be chained with the -TPS2AM. A single-pair sender must be set to feed pair C if it is connected together with the -TPS2AM. The power pair and all three audio pairs are fed through both rear-panel RJ45 jacks. The D SERIES-TPS2AM 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 -TPS2AM 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.
