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-NL2 is a line-level interface that converts two Dante network audio channels to two 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-NL2
is a professional grade product for studio quality fidelity and low noise performance.

The AV-NL2 may be powered from an external 24 Vdc power supply, available separately. The AV-NL2 is equipped to operate from a PoE
enabled network switch. The AV-NL2 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-NL2, 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-NL2 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.
