PowerCenter Pro 3500 with Clean Power Stage 3, Tri-Mode Protection, (12) Outlets, 2775 Joules - MP PRO 3500 14 Power Outlets Warranty: N/A Ordinary AC power accessories don’t increase the performance of the equipment they power. The PowerCenter’s advanced technology and innovative design offers several patented convenience and performance features. While the PowerCenter also does an excellent job of protecting your equipment from harmful power surges, its main performance benefit is much more than just surge protection. The Clean Power filter circuitry virtually stops noise that goes right through ordinary surge protectors.Since there is more than one type of noise that can degrade connected equipment, the PowerCenter features revolutionary separate noise isolation between digital and analog filtered outlets. If any noise from components sharing the powerline gets through one Clean Power filter, it will have to go through another filter to get to an adjacent set of outlets. The result is an extremely low noise floor without hum or buzz that allows all of the rich harmonics and tone to come through your performance.
