APC's C5 Power Filter gives you 10 surge-protected and filtered outlets. Four of these outlets have EMI/RFI noise filtering for digital devices such as HDTVs, DVRs, and DVD players. There are also two analog, two video, and two high current (amplifiers, subwoofers) filtered outlets. Component-specific noise filtering banks prevent video and audio signal distortion. You also get surge protection and isolated noise filtering. Power filtering is a much-needed solution that eliminates stress on component power supplies, eradicates EMI/RFI and voltage fluctuation as a source of AV signal degradation, and protects equipment from damaging surges, spikes voltages, and lightning. If you live in a place where electrical noise and radio frequency interference is severe enough to affect picture and sound quality, this APC filter can improve your cinematic experience by allowing the equipment to perform to its maximum capabilities. Inductorless filtering for high current components is also included.
