AV-PAK products are heavy duty modules intended for rugged field use. Functions include interface, isolation, ground-lift and signal dividing/combining and amplification. AV-PAKs are engineered to provide higher performance and better shielding than other industry products. Standard connector types are provided for direct connection and operation by end users. The heavy duty extruded aluminum and steel chassis are finished in a high quality powder coat. The heavy chassis and dark color style make AV-PAKs ideal for both stage use and permanent installation. AV-PAK modules are designed and manufactured in the U.S.A.

Application
The AV-NL4 is a line-level interface that converts four Dante network audio channels to four balanced audio outputs on XLR connectors. Each channel provides +4 dBu balanced for a network digital audio level of -20 dBFS. Each output is equipped with a selector to set the output to line level or attenuate the output by 50 dB to mic level. Special software is not required to configure the module. The AV-NL4 is a professional grade product for studio quality fidelity and low noise performance. The AV-NL4 may be powered from an external 24 Vdc power supply, available separately. The AV-NL4 is equipped to operate from a PoE enabled network switch.

The AV-NL4 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-NL4, 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-NL4 is constructed in
