Unlike standard surge protectors, the Monster PowerCenter™ AV800 with SurgeGuard™ protection provides multiple layers of defense against harmful surges. Strategically placed multiple Metal Oxide Varasitors respond within one nanosecond (a billionth of a second) to power surges and voltage spikes before they can reach and damage your audio video components. Plus, Monster's ultra-low loss RF circuitry minimizes signal loss to maintain the peak output performance of your coax connections.
