Product Description
RDL AV-LN4 Line Level Audio to Network Interface
Overview
The AV-LN4 is an interface that converts four line-level XLR inputs to Dante network audio channels. Special software is not required to configure the AV-LN4. A dual-LED VU meter displays the level for each. The AV-LN4 is a professional grade product for studio quality fidelity and low noise performance.
The AV-LN4 may be powered from an external 24 Vdc power supply, available separately. The AV-LN4 is equipped to operate from a PoE enabled network switch. The AV-LN4 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 AV-LN4, the unit will run from the external supply and will seamlessly switch over to PoE power upon loss of the external supply. Valid power and synchronization to the Dante network is indicated by a green LED visible from the front of the unit.
The AV-LN4 is constructed in a durable, professional all-metal enclosure suitable for use on stage or in studio, or mounted to any flat surface. For fixed installations, mounting brackets are included. The chassis is designed to protect the front panel slide switches from accidental damage. This full-featured AV-PAK product is engineered and manufactured in the U.S.A for continuous duty in demanding installations.
