I/O Interfaces

RDL – RU-LB4P

The RU-LB4 is a high quality line-level bi-directional Dante network interface. The RU-LB4 converts four line-level audio sources to Dante network channels, and four Dante network audio channels to balanced line level. Input gain trimmers and LED audio level indicators are provided. Model RU-LB4P operates from PoE.

The RU-LB4 is a high quality line-level bi-directional Dante network interface. The RU-LB4 converts four line-level audio sources to Dante network channels, and four Dante network audio signals to balanced line level.

The line level inputs accept unbalanced or balanced signals. Line-level outputs are balanced. The front panel features signal LEDs that indicate audio presence for each of the received network signal channels and a gain trimmer with an associated Dual-LED VU meter for each audio input. 

Balanced +4 dBu audio levels correspond to a network digital audio level of -18 dBFS. The noise floor is better than 80 dB below operating level.

The RU-LB4 is also available in a PoE version (RU-LB4P). If PoE power and an external 24 Vdc supply are both feeding an RU-LB4P, the unit will run from the external supply and will seamlessly switch over to PoE power upon loss of the external supply.
