RDL RU-FN – Format-A to Dante Interface
What is the RDL RU-FN?
The RDL RU-FN is a RACK-UP Format-A receiver that converts RDL Format-A twisted-pair audio to Dante network channels. Format-A pairs A, B and C each become a Dante channel, and a fourth channel comes from a balanced or unbalanced aux line input. It extends existing RDL Format-A wall plate and sender systems onto a Dante network.
How does it work?
Format-A connections run on RJ45 jacks over CATx cable, and each sender can be near the RU-FN or up to several thousand feet away. The Format-A input supplies up to 200 mA to connected senders, and multiple senders can be daisy chained. Front-panel green LEDs show the received audio level on each of the three Format-A pairs, which helps setup without a networked computer on site. The aux input accepts the full range of unbalanced and balanced line-level sources, with a front-panel gain control and dual-LED VU meter. High-resolution 24-bit converters and RDL analog filtering deliver a very low noise floor. LEDs show Dante network sync status. The RU-FN is powered from an external 24 Vdc supply, available separately, which also powers the Format-A senders connected to its input; RDL recommends its PS-24AS (USA) or PS-24AX (international) 24 Vdc supply. The module is equipped for rack or surface mounting with RDL RACK-UP accessories such as the RU-HRA1 10.4-inch rack mount, RC-1UR 19-inch universal rack chassis, RU-SMA1 surface mounting plate and RU-BR1 under-surface bracket.

Frequently Asked Questions
What is RDL Format-A?
Format-A is RDL's twisted-pair system that carries up to three audio pairs plus power over CATx cable between RDL senders and receivers.
How far can Format-A senders be from the RU-FN?
RDL states that each Format-A sender may be connected near the unit or up to several thousand feet away.
How is the RU-FN powered?
It requires an external 24 Vdc supply (24 Vdc at 100 mA plus connected loads). RDL recommends the PS-24AS (USA) or PS-24AX (international). The RU-FNP version adds PoE.
Can I also send Dante audio back out as Format-A?
Yes, with a separate network-to-Format-A unit such as the RDL RU-NFD.
What warranty does the RU-FN carry?
This product is covered by a 7-year RDL warranty. For warranty claims, RMAs or support, contact Creation Networks at (888) 230-3661 or sales@creationnetworks.net.
