*The above curves were made by combining the measured responses of the UltraPure I's Input Filter section, transformer section, and Second Filter sections. The reduction in noise is exactly the same whether the it is originating from your AC line or from a switchmode power amp plugged into Output 4 of the UltraPure I.

What Does the Graph Show? The accompanying graph shows the reduction of noise at various frequencies from incoming power line or Output 4 (switchmode outlets) to symmetrical Output 1, designed to feed the most sensitive front-end audio components. The UltraPure I Solution The UltraPure Symmetrical Wideband Filter uses a combination of multi-stage, heavy-duty filters, balanced isolating transformers, and a second set of AC line filters to reject both Common-Mode and Differential Mode AC noise and RFI from the AC outlets feeding your sensitive audio/video equipment. The UltraPure's noise reduction capability extends to much lower frequencies than competing AC filters. At the relatively low frequency of 200kHz, UltraPure reduces differential mode noise by a factor of 3 million to 1, and common-mode noise is reduced by 100 million to 1! This exceptional low frequency rejection means that neither externally generated noise, nor noise backfeeding from a switchmode power amplifier will ever reach your sensitive front-end components.
