The Monster HTS 1000 MKIII features over 6125 Joules of extreme protection that can absorb powerful surges and spikes. Microprocessor controlled T2 circuitry, a Monster Power exclusive, not only protects your AV equipment, but protects your PowerCenter as well. The HTS 1000 MKIII's T2 protection circuitry automatically disconnects the PowerCenter and all of your connected AV equipment when it senses dangerous power conditions, completely isolating them from potentially damaging sags, spikes, and surges. T2 continues to actively monitor power conditions, then automatically reconnects when AC power returns to normal. In addition, Monster's Tri-Mode protection circuitry incorporates an audible alarm that will tell you when your PowerCenter has protected your AV system from damage.
