Brand New in Retail Package! Monster Clean Power Circuitry Stage 2 filters provide excellent AC power line noise rejection and isolation of audio and video equipment for component-generated noise rejection. When you connect your home theater components to a Monster HTS 1000 MKIII PowerCenter you`ll get the best possible picture and sound from your components with a more natural sound, increased dynamic range, and the most vivid video images possible. The Monster HTS 1000 MKIII features 6125 Joules of extreme protection that can absorb powerful surges and spikes. Unlike ordinary surge protectors, advanced Monster PowerCenters also actively monitor incoming power disturbances and automatically disconnect your valuable equipment before damage occurs. The HTS 1000 MKIII then sounds an alarm to let you know that all of your equipment has been protected. When the power disturbances have gone away the HTS1000MKIII turns back on and gives power to all of your components. UPC# 050644483271
