0ur opinion:Item Description:Unless you live directly behind Hoover Dam, your AC power is most likely 'polluted' by appliances sharing the same power line with your home theatre components. Electrical power tools, refrigerators, air conditioners, radio transmitter, cellular phones, microwave ovens, even your neighbor's freezer, all generate electromagnetic interference and radio frequency noise, which pollutes the AC power and degrades audio and video performance. And you'll never know how much of the essential drama is gone in the high-performance picture and sound your home theatre was designed to deliver.Harmful power surges and voltage spikes can travel up the AC power line and damage connected equipment. Lightening, automatic garage doors, power tools, refrigerators and fluorescent lights all cause power surges and voltage spikes that affect phone lines and coax cables. Monster's Multiole SurgeGuard detects harmful power surges and voltage spikes before they reach components. This PowerCenter HTS8OO features special surge protection for phone lines and coax cables used for DSS, DlVX /DVD and cable TV connections. 0ther surge protectors can result in as much as 2O to 3OdB of signal loss, which ultimately affects the output performance of coax connections. Monster's ultra-low loss RF circuitry provides virtually no signal loss to maintain peak performance. Clean Power Circuitry uses special filters to dramatically reduce electronic noise on your AC power line to give you the best possible sound and picture from your components. You'll see a more vivid picture and hear more natural sound with increased dynamic range and less noise - especially if your AC power is severely polluted. You'll get back the performance you never knew you lost. Best of all, an audible surge alarm and visual surge indicator warn you of harmful surges and let you know you're getting the most advanced protection available. ln the end, you'll get all the performances you paid for...and isn't that what it's all about?
:The fact is, analog audio equipment is sensitive to a different type of noise than video, just as video is sensitive to a different type of noise than digital, and so on. ln the past, manufacturers have used filters to combat the problem of noise introduced via power sources. Unfortunately, the filters were not optimized to attenuate at the different frequencies that are unique to digital, analog audio, and video realms. Products that managed to deliver truly cleaner AC power were thousands of dollars in price, out of reach for most people. Enter Head Monster Noel Lee. An uncompromising audiophile, Lee joined forces with Richard Marsh, the world’s foremost expert on AC power, to develop affordable solutions to AC power problems. The result? Monster Clean Power.

More Than Just Surge! -Monster Clean Power The following overviews of Monster’s isolated, specially tuned Clean Power filters demonstrate the methodology behind Clean Power’s development. The higher the Clean Power stage, the more advanced the noise filtration. The more advanced the noise filtration, the higher the level of component-to-component isolation.
lsolated Clean Power Digital Filters
0ptimized to reduce noise generated by digital equipment digital filters isolate digital components from connected analog audio and video components for maximum rejection of interference.
lsolated Clean Power Video Filters
0ptimized to reduce noise generated by video equipment, video filters isolate video components from connected digital and analog audio components for maximum rejection of interference.
lsolated Clean Power Analog Audio Filters
0ptimized to provide maximum noise rejection for sensitive analog audio components, audio filters isolates audio components from connected digital and video components for maximum rejection of interference.
lsolated Clean Power Ultra-High Current Filter
0ptimized for maximum noise rejection, ultra-high current filters provide maximum current to high power components such as surround sound amplifiers. Reference Home Theater Power Monster PowerCenters also offer the most comprehensive home theater system protection available, featuring higher joule ratings for faster acting, full capacity surge protection. Monster’s Multiple SurgeGuard and Tri-Mode Circuitry instantly detects any voltage surge or spike and immediately suppresses it before it can reach your components. And, for your total peace of mind, the latest generation of Monster Home Theatre Reference PowerCenters come with higher Connected Equipment Guarantees (CEGs).
Unlike other surge protectors, the PowerCenters’ ultra low-loss RF circuitry provides maximum protection with virtually no signal loss, especially important with the advent of HDTV. ln addition, all PowerCenters display current draw and voltage.
Monster recognizes that convenience is vital, too. The PowerCenters feature component-assigned color coding with matching power cord labels for easy identification, and all are rack mountable, for easy integration into custom installed rack mount systems.
Get All The Performance You Paid For With Monster Power’s Home Theatre Reference PowerCenters, you’ll get the best possible audio and video performance from your home theater system.

* Pretty Good ...
l have no problems with it and i like how the ports are all labeled and spread out.

lt works, l guess.
Replaced my ancient surge protector with this power strip that acts not only as a surge protector, but power conditioner. Does it really work? l have no idea. My municipal utility has always delivered high quality power, so l have no idea if the power conditioning is adding any value. Just a leap of faith on my part. l can't notice any difference in my picture quality. l figure it can't hurt and can only help.
l do like the ergonomic features. Certainly color coding and labeling of which plug is for what piece of equipment is great! No more searching for the right plug. l also like the fact that they provided 2 widely spaced plugs so wall-warts can fit. Those design features are certainly worth a premium over your average power strip.

l Guess That it Works
This surge protector was a "throw in" from the dealer where l recently bought my HDTV. Would l have actually bought it otherwise? Probably not.
Sure, it's specs are impressive and it seems to be built well. l also like the fact that the outlets are spaced widely enough to plug in a wallwort power source or two.
The "problem" with stuff like this is that, unless you have some way to test it, there's no way to tell if it's providing a cleaner throughput than just plugging your gear into a wall outlet.
Now l certainly don't recommend not using a surge protector on expensive electronics. l have them on my main HT system, my bedroom HDTV and DVD player and my computer gear. lt's certainly cheap insurance.
Monster has been around for years and l've used some of their cables. l've often asked myself whether or not their extra cost is worth it. All l can answer is that Monster products provide me with a sense of security (falsely or otherwise) so l guess the peace of mind makes the $5O item worth more than the $1O item.

* the difference is visable ...
being the "techno-goober" that i am, i can tell a difference between this and the power-strip that i used before.
this cleans the power that arrives at your devices.
i used to have "flubs" in power going to my devices causing them to flicker, or sound to go "wonkey".
i currently have plugged into this:
my 32" HDTV, Digital Cable Box (with HD out) DVD/Surround Sound and my x-box.
i've been using this for about a month now and i can tell a clear difference. a recommended product for anyone with expensive equipment that you want to keep in full working order.

Who knows exactly how good it is?
l haven't placed a scope on the input or output therefore, l don't know how good job of filtering and protection it provides. All components connected to it perform well. l was told by my cable co. not to put the cable or phone line through it because when the cable box is updated every few days that it will not come through this unit. Therefore, l don't run my cable conection through it. lt is a very user friendly and attractive unit.
l'm well pleased with the price from [...].
