RDL RU-NFD Dante Network to Format-A Interface/Distributor

The RU-NFD is an RDL Format-A sender/distributor that connects to a Dante-enabled network. It converts three Dante audio channels to RDL Format-A. Each network channel corresponds to Pair A, B or C of the Format-A outputs. The unit converts a fourth Dante audio channel to a balanced line-level AUX output.

The RU-NFD is powered from an external 24 Vdc power supply, available separately.

Features:

• Converts Four Dante Network Audio Signals to RDL Format-A and Aux
• Easy Installation with Format-A Connections on RJ45 through CATx Cable
• Three Dante Audio Signals Feed Format-A Output Pairs A, B and C
• Fourth Dante Audio Signal Feeds Auxiliary Balanced +4 dBu Line Output
• Format-A Pairs are Distributed to Three Separate Format-A Output Jacks
• Signal LEDs Indicate Audio for Each of the Four Received Network Signal Channels
• High Resolution 24 Bit Digital to Analog Conversion
• Legendary RDL Analog Filtering Enhances Superb Audio Performance
• Powers Remote Format-A Receivers through Primary Output Jack
• External 24 Vdc Supply Powers Format-A Receivers through All Output Jacks
• LED Indicators Show Network Sync Status
• Outputs Mute when Digital Audio Inputs are Inactive
• Compatible with Wide Array of RDL Format-A Active and Passive Receivers
• Equipped for Rack Mounting or Surface Mounting

The RU-NFD modules are Dante audio network interface products compatible with RDL Format-A twisted pair products. These modules are designed to be mounted in equipment racks, closets, conference tables and on shelves or backboards in commercial/industrial installations.

APPLICATION: The RU-NFD is an RDL Format-A sender/distributor that connects to a Dante-enabled network. It converts three Dante audio channels to RDL Format-A. Each network channel corresponds to Pair A, B or C of the Format-A outputs. The unit converts a fourth Dante audio channel to a balanced line-level AUX output.

One front-panel green signal LED corresponds to each of the four Dante input channels. Received audio level is indicated on the variable-intensity LED indicator, facilitating setup when a networked computer is not connected at the module's location.

The Format-A output is distributed to three separate rear-panel RJ45 jacks. Each Format-A output jack provides up to 200 mA of power to connected Format-A receivers. Multiple receivers may be daisy chained from one output jack, or may be connected by home run to each of the three outputs. Higher current Format-A receivers, such as RDL D-PSP1A powered Decora-style speakers, are to be individually connected to a separate output jack.

The RU-NFD output jacks support the entire range of Format-A receivers, making each output pair available for end-user connection on various wall plates, or feeding other equipment using rack-mounted, shelf-mounted or utility Format-A receivers. The wide array of Format-A receivers provide compatibility with commercial audio equipment operating at standard professional levels. High resolution digital audio converters coupled with RDL's renowned analog filters provide superior fidelity with a very low noise floor. Each Format-A receiver may be connected near the RU-NFD or up to several thousand feet distant.

The RU-NFD is powered from an external 24 Vdc power supply, available separately. The external supply powers the RU-NFD and Format-A receivers connected to all three Format-A outputs. The RU-NFDP is equipped for PoE which powers the RU-NFD and Format-A receivers connected to the primary Format-A output jack. Audio is also distributed to the other two output jacks. Remote Format-A receivers connected to those other two output jacks are only powered from the RU-NFDP if an external 24 Vdc power supply is connected. If PoE power and an external 24 Vdc supply are both feeding an RU-NFDP, the unit will run from the external supply and will seamlessly switch over to PoE power upon loss of the external 24 V supply. The power feeding each Format-A RJ45 connector is separately protected by an automatically resetting fuse. A power LED is associated with each connector, facilitating identification of wiring faults.

PoE relies on the use of a PoE enabled network switch. The RU-NFDP will reserve power from the switch even while being powered from an external 24 Vdc supply.

The RU-NFD is constructed in a durable, professional all-metal enclosure suitable for free-standing, surface-mounted or rack-mounted operation. This full-featured product is engineered and manufactured in the U.S.A for continuous duty in demanding installations. Built to last. Built to outperform.
