Description

The RU-LB2 modules are Dante audio network interface products compatible with line-level audio equipment inputs and outputs. 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-LB2 is a high quality converter that provides professional line-level outputs from two Dante network received audio channels. It also converts two professional or consumer line-level sources to Dante network audio channels.

Network to Line Level Interface Section

The RU-LB2 converts two Dante audio channels to balanced line level. Each output provides +4 dBu balanced for a network digital audio level of -18 dBFS. The professional output directly interfaces with other professional and commercial equipment without the need for additional gain. Crosstalk is below the noise floor between all outputs across the entire audio spectrum. The noise floor is better than 80 dB below operating level.

One front-panel green signal LED corresponds to each of the two 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.

Line Level to Network Interface Section

The RU-LB2 converts two line-level audio sources to Dante networked digital audio channels. Each input is equipped with a front-panel gain trimmer and associated Dual-LED VU meter to facilitate optimal input gain adjustment. Each input supports the complete range of normal unbalanced -10 dBV and balanced +4 dBu line-level sources. Input gain adjusted according to the Dual-LED VU meter assures an operating level that preserves full headroom with the lowest noise floor.

The RU-LB2 is powered from an external 24 Vdc power supply, available separately. The RU-LB2P is equipped to operate from a PoE enabled network switch. The RU-LB2P will reserve power from the switch even while being powered from an external 24 Vdc supply. If PoE power and an external 24 Vdc supply are both feeding an RU-LB2P, the unit will run from the external supply and will seamlessly switch over to PoE power upon loss of the external supply.

The RU-LB2’s superior performance specifications make it ideally suited to the most demanding installations, and an exceptional value in commercial networked audio systems.

The RU-LB2 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.
