A NOTE FROM THE HEAD MONSTER
Dear Enthusiast,
THANK YOU for purchasing the Monster Power® Home Theatre In-Wall PowerCenter™.
This PowerCenter reflects our commitment to creating performance-enhancing solutions
for home theater systems that deliver superior sound and picture quality.
As a long-time audiophile and serious home theater enthusiast, I always knew problematic AC
power could degrade picture and sound quality. Unfortunately, ordinary AC power accessories
can compromise the performance of the components they power. So, with the help of Richard
Marsh and other power experts, I decided to address the issue and created Monster Power.
The Monster Power In-Wall Power Center protects components from harmful power surges,
but its benefits include much more than just surge protection. The patented Monster CleanPower™
filter circuitry minimizes electromagnetic and radio frequency noise that goes right through typical surge protectors.
The result is sound and picture that’s free from performance-damaging interference. It also features surge-protected
AC outlets and coaxial connections, a 1260 joule rating with new three-mode MOVs, inserts including surge protected
coaxial connectors, and SurgeGuard™ diagnostic indicators with an audible alarm.
These days, home theater components are better than ever, providing thrilling and dramatic sound and razor sharp
picture. We know your new PowerCenter will help bring it all together with Clean Power and superior system protection.
With Monster Power, you’ll enjoy the best possible sound and picture. And that’s what home theater is all about.
