AV-PAK products are heavy duty modules intended for rugged field use. Functions include interface, isolation, ground-lift and signal dividing/combining. 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 dark gray. Lettering is on a dark background with a protective polycarbonate overlay. The heavy chassis, dark color style and protected graphics make AV-PAKs ideal for both stage use and permanent installation. AV-PAK modules are designed and manufactured in the U.S.A.
