Active Two-Pair Sender Dual Microphone Preamplifier - Format-A - Stainless - Radio Design Labs DS-TPSM2A

The D SERIES-TPSM2A 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 -TPSM2A models mount in RDL WB-1U and WB-2U wall boxes, or in standard U.S. electrical boxes. The D-TPSM2A features a white front-panel laminate with gray lettering that matches RDL Decora©-style remote controls. The DB-TPSM2A features a black front-panel laminate. The DS-TPSM2A is constructed of stainless steel to coordinate with RDL Decora-style stainless steel remote controls in commercial/industrial installations.

APPLICATION: The D SERIES-TPSM2A modules feature two XLR microphone inputs. The module provides IEC 48 V phantom (P48) and accepts input signals from both dynamic and condenser microphones. The input signals are amplified using studio-quality microphone preamplifiers optimized for normal operating levels. The rear-panel GAIN switch is normally set by the installer for AUTO (automatic) gain. The module automatically sets the gain to 60 dB for dynamic microphones or 40 dB for condenser microphones. If consistently low mic levels are expected, this switch may be set to the HIGH gain position. If the module is used only with condenser microphones, the switch may be set to LOW gain. Each pre-amplified microphone source is routed to one output cable pair selected during installation using a rear-panel switch.

These modules drive only two cable pairs, therefore they accept a signal and power from another mic-level or line-level Format-A sender. The D SERIES-TPSM2A modules have a second RJ45 jack for that input cable. One single-pair sender may be chained with the -TPSM2A. If two senders are connected together, each audio source must feed a different pair: A, B or C. The power pair and all three audio pairs are fed through both rear-panel RJ45 jacks.

The D SERIES-TPSM2A must 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.

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.
