The D SERIES-TPSML1A modules feature an XLR microphone or line input. The module provides IEC P24 phantom and accepts input signals from balanced line-level sources or from both dynamic and condenser microphones. The input signal is buffered or amplified using a studio-quality preamplifier optimized for normal operating levels. For microphone sources, the rear-panel GAIN switch is normally set by the installer for MIC LOW gain. If consistently low mic levels are expected, this switch may be set to the MIC HIGH gain position. For line-level sources, the GAIN switch is set to LINE. In either MIC gain position, the PHANTOM voltage is used to set mic phantom ON or OFF. Phantom voltage is not applied when the input is set to LINE.

The pre-amplified input source is routed to one Format-A output cable pair, A, B or C, selected during installation using a rear-panel switch. Two other single-pair senders may be chained with the -TPSML1A, 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 -TPSML1A 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 SERIES-TPSML1A 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 -TPSML1A may be remotely powered through the twisted pair cable from any other Format-A module, signal distributor or RDL power inserter connected to the same twisted pair cable. Module power is indicated by a front-panel LED in the XLR jack.

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.
