OUR PART # DB-TPSL2A
The Radio Design Labs DB-TPSL2A module is a two-pair audio sending module compatible with RDL Format-A twisted pair products. This module is designed to be mounted in wall boxes, cabinets or other enclosures that allow users to connect audio sources.
The DB-TPSL2A module features an XLR microphone input and two RCA phono jack inputs summed to mono. 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 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) gain. 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 summed left and right line-level inputs are routed to output cable pair B.
This module drives only two cable pairs, therefore it accepts signal and power from one mic-level or line-level Format-A single-pair sender. One single-pair sender may be chained with the DB-TPSL2A. A single-pair sender must be set to feed pair C if it is connected together with the DB-TPSL2A. The power pair and all three audio pairs are fed through both rear-panel RJ45 jacks.
The DB-TPSL2A may be powered directly from a 24 Vdc power supply using the detachable terminal block. Local power connected to the module is also fed to all connected remote modules. The DB-TPSL2A 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.
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.
NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product. Please click here for more information on the PS-24AS power supply.
