RU-NFDP

RDL RU-NFDP - Dante network interface and distributor for twisted pair Format-A with 3 RJ45 outputs and a balanced AUX output, powered by PoE

The RDL RU-NFDP is a Dante network interface for RDL devices operating in the Format-A transmission system over twisted pair. It receives four Dante audio channels from the network. Three of them are directed to pairs A, B, and C of Format-A and distributed to three RJ45 outputs, while the fourth is sent to a balanced AUX line output. This allows for easy transfer of audio from the Dante network to Format-A receivers located throughout the facility, using standard CAT-x cabling. Each RJ45 output provides up to 200mA, thus powering connected remote Format-A receivers. The device can be powered by an external 24V DC power supply or via PoE. The 24-bit digital-to-analog processing with RDL's analog filtering ensures high sound quality. When the Dante audio inputs are inactive, the outputs are automatically muted. Green signal LEDs for each channel, along with network synchronization and power indicators, facilitate system setup and monitoring. The interface has a metal housing and can be mounted in a rack, on a surface, or set up freestanding.

RDL RU-NFDP is a Dante interface for Format-A that converts four network channels into three RJ45 twisted pair outputs and a balanced AUX output. Powering receivers from the outputs, operation with PoE, automatic muting, and a metal housing make it well-suited for sound installations, conference rooms, and audio distribution systems based on the Dante network.
