The Radio Design Labs RU-FN is an RDL Format-A receiver that connects to a Dante-enabled network. It converts the three Format-A audio pairs to Dante networked digital audio channels. Each network channel corresponds to Pair A, B or C of the Format-A input. The unit converts a fourth input, balanced or unbalanced line-level AUX, to Dante.

One front-panel green signal LED corresponds to each of the three Format-A 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. A Dual-LED VU meter facilitates adjustment of the front-panel AUX input gain control. The AUX input supports the complete range of normal unbalanced and balanced line-level sources.

The RU-FN is powered from an external 24 Vdc power supply, available separately. The external supply powers the RU-FN and Format-A senders connected to the Format-A input. The RU-FNP is equipped for PoE which powers the RU-FN and the connected Format-A senders. If PoE power and an external 24 Vdc supply are both feeding an RU-FNP, 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 the Format-A RJ45 connector is separately protected by an automatically resetting fuse. A power LED is associated with the connector, facilitating identification of wiring faults.
