AC power line noise is everywhere in our modernized world. Appliances we use every day such as computers, refrigerators, washers, dryers, and air conditioning units, just to mention a few, can generate noise on the AC circuits you use to power your audio and video equipment.

Most home entertainment devices have little or no AC filtering to prevent these AC line noises from causing their damage. Eliminating the noise and RFI from your AC line means that your equipment will not have to amplify and process noise and RFI along with the audio and video signals.

How Does It Sound?
Eliminating the noise and RFI from your AC line means that your equipment will not have to amplify and process RFI along with the audio and video signals. The resulting lower system noise floor will allow more low-level subtleties like room reverb and precise imaging to come through. Midrange clarity is improved when the audio amplifiers don't intermodulate with RFI, and the digital circuitry will tend to sound less "jittery". Using an UltraPure II to provide your system with clean, wideband filtered AC power, will allow you to fully experience and enjoy all the promised performance from your system.

The UltraPure Solution
The UltraPure II Wideband Filter uses a combination of multi-stage, heavy-duty filters, 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 above curves were made by combining the measured responses of the UltraPure II's Input Filter section and Second Filter section. The reduction in noise is exactly the same whether it is originating from your AC line or from a switchmode power amp plugged into Output 4 of the UltraPure II.

What Does the Graph Show?
The accompanying graph shows the reduction of noise at various frequencies from incoming power line from Output 6 to Output 1, designed to feed the most sensitive front-end audio components.

The UltraPure Solution
The UltraPure II 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 1 million to 1, and common-mode noise is reduced by 300,000 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 head end components.
