RU-NFD

RDL RU-NFD - Dante network interface/distributor to Format-A over twisted pair with AUX output

The RDL RU-NFD is an audio Dante interface from Radio Design Labs that connects the Dante network to RDL Format-A devices transmitting signals over twisted pair. The module operates in the Dante network as a transmitter and distributor of Format-A. It is designed for rack enclosures, technical rooms, conference tables, shelves, and mounting panels in commercial and industrial installations. Three Dante channels are converted to Format-A pairs A, B, and C, while the fourth channel goes to a balanced AUX +4dBu line output. The Format-A signal is distributed to 3 RJ45 sockets on the rear panel, each capable of powering receivers with up to 200mA. Receivers can be daisy-chained or connected via separate lines, and they can be located at a considerable distance from the module. Receivers with higher power consumption, such as RDL D-PSP1A active speakers in Decora style, require a separate output socket. Green signal LEDs with variable brightness for each of the 4 channels facilitate configuration in locations without a computer connected to the network. Each RJ45 output has its own self-resetting fuse and power LED, making it easier to diagnose wiring errors. The RU-NFD is powered by an external 24V DC power supply (available separately), which powers the module and receivers on all 3 outputs. A PoE-powered variant is offered as a separate model RU-NFDP. The completely metal housing, manufactured in the USA for continuous operation, allows for rack or surface mounting. The product is covered by a 7-year manufacturer's warranty.

Functionality

• Conversion of 4 Dante audio signals to Format-A and AUX output
• 3 Dante channels to Format-A pairs A, B, and C
• 4th Dante channel to balanced AUX +4dBu line output
• Distribution of Format-A pairs to 3 separate RJ45 sockets
• Powering Format-A receivers up to 200mA on each output
• Daisy-chaining or radial wiring of receivers
• External 24V DC power supply powers receivers on all outputs
• Self-resetting fuse and power LED on each RJ45 output
• Green signal LEDs with variable brightness for each of the 4 channels
• Dante network status and synchronization LEDs
• 24-bit C/A conversion

• Automatic muting of outputs in the absence of an active digital signal
• Headroom above 18dB on Format-A and AUX outputs

Features

• Simple installation - Format-A via RJ45 connectors and CATx cable
• Easy integration of Format-A systems with the Dante audio network
• Compatibility with a wide range of active and passive Format-A receivers
• Powering receivers directly from the module - no local power supplies at receivers
• Signal transmission to receivers located at long distances
• Convenient configuration without a computer thanks to signal LEDs
• Quick diagnostics of wiring errors on each output
• Silence on outputs in the absence of a signal - no unwanted noise in the system

RDL RU-NFD is a practical interface that distributes audio signals from the Dante network to Format-A receivers over twisted pair. Three secured RJ45 outputs with receiver power, an additional AUX output, clear diagnostics, and solid construction make it a convenient solution for expanding audio installations with listening points and Format-A speakers.
