OUR PART # D-TPS1A
NOTE: Radio Design Labs' PS-24AS power supply is NOT included but is required in order to power this product. Please see the "Accessories" tab or click here for more information on the PS-24AS power supply.
Radio Design Labs' D-TPS1A modules is a single-pair audio sending module that is 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 D-TPS1A mounts in RDL's WB-1U wall box, or in a standard U.S. electrical box. 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 preamplifier optimized for normal operating levels. The rear-panel GAIN 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 one output cable pair selected during installation using a rear-panel switch.
This module drives only one cable pair, therefore it accepts signals and power from other mic-level or line-level Format-A senders. The D-TPS1A has a second RJ45 jack for these input cables. Installers simply connect the conductors of two cables in parallel on the EM- model terminal block. 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 may be powered directly from a 24 V DC 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.
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.
