This contaminated power can affect audio/video equipment and will degrade the overall performance of your entire system. Common symptoms of contaminated power include pops, hisses, hums and visual artifacts. The MAX 5400-EX is designed to filter this noise, supply clean power to your system and provide noise isolation between the outlet banks so that any noise created by an A/V com- ponent can not contaminate the power going to equipment plugged into the other outlet banks. Model: M5400-EX
