Monster multiple surge guard circuitry absorbs harmful power surges to give you audio video system protectionharmful power surges and voltage spikes can travel up ac power and coax connections and damage your components. Lightning, automatic garage doors, power tools, refrigerators and fluorescent lights all cause power surges and voltage spikes that can travel up ac power lines and coax cables to damage the sensitive electronic circuitry of your connected audio video components. Ordinary surge protectors, or the so-called "value brands", often fail to provide the adequate level of protection your av components need. Plus, standard surge protectors often cause as much as 20 to 30db of signal loss which can adversely affect the output performance levels of coax connections. Proper connection to an advanced surge protector that offers integrated system protection can help minimize the risk of permanent surge damage. 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. monster PowerCenters make life easier. Monster's flatprofile plug lets you push your furniture flush against the wall. And, with color-coded outlets and cord labels, you can avoid unplugging your VCR by mistake, causing it to blink "12:00". Finally, a generous eight-foot monster power cord, which is the optimum length to reach most electrical outlets, is included. Now you can get protection from harmful surges, voltage spikes and inconvenience! Monster's PowerCenters offer high performance solutions for today's technology challenges.
