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-XMN4 is an interface that converts four XLR microphone inputs to Dante network audio channels. Special software
is not required to configure the AV-XMN4. Each XLR input is equipped with a switch to set the gain for dynamic or condenser microphones.
A dual-LED VU meter displays the level for each input to facilitate selection of the ideal gain range. P48 phantom voltage is supplied to each
microphone input. The AV-XMN4 is a professional grade product with discrete mic preamplifiers for studio quality fidelity and low noise
performance.

The AV-XMN4 may be powered from an external 24 Vdc power supply, available separately. The AV-XMN4 is equipped to operate from a PoE
enabled network switch. The AV-XMN4 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-XMN4, 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-XMN4 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.
