Welcome to Alan Maher designs.  Our philosophy is very simple; Everyday our audio/video components are plagued by harmonic distortion created by power fluctuations, dirty power grid, poorly rough-in electrical wiring, and every single component/appliance plugged into the electrical service panel in our home.  There have been multiple products introduced to deal with the noise traveling throughout the home; some products offer substantial improvements, and others offer little to no improvement.   The one area where all these products/concepts fail is the lack of vision to deal with the true noise source.  Noise comes in many different forms: RFI, multipath waves, EMI, low and high voltage, etc.  Everything wired between point A to point B creates some kind of distortion; the trick is to either absorb or re-tune as a way to filter the noise.  Up to now, absorbing the noise via a typical filtered circuit has failed miserably - the end result is usually too much saturation causing a steep harmonic roll off affecting the operating frequencies of the circuit board components, congestion, loss of dynamics, loss of true tonal reproduction, video clipping, loss of video depth, color saturation, etc.  In mid-to-late 1998, I developed a re-clocking circuit to re-tune the harmonic structure of odd harmonics riding above the 50/60Hz sine wave, now widely known as PE technology.  The circuit is designed to fill in the harmonics dips and lower peak harmonics in order to create a ruler-flat frequency response up to a particular cut frequency.  The end result is realistic musical dynamics, tonal reproduction, soundstage, low and high band extension, increased video resolution, depth, detail, and true to life color and hue reproduction. 

As previously mentioned, noise comes in many different forms.  No one filter design can deal with all of them at one time, requiring the need for specialized filters to deal with individualized problems.  Power conditioners, like high-end audio/video components, run into the same problem when multiple manufacturer products are thrown into the mix.  For example, if you own a Krell set-up, all Krell components sound fabulous when used together; but if you throw something like a Theta into the mix, the sound quality goes all haywire.  The reason for it is because Krell and Theta fine-tune their power supplies to a standard frequency to define their signature sound, but it also eliminates power supply harmonic cross-talk when all components are plugged into the same electrical hub.  When power supplies are tuned to multiple different frequencies, you get multiple different odd harmonics distorting the circuit.  The end result is one distortion modulates into another distortion, creating a third multiple, and this goes on forever - making it a never ending battle to clean up the noise.  Taking all that into account, we developed specialized circuits with multi-frequency networks to combat modulated distortion and eliminate cross-talk distortion.  The basic harmonic networks all communicate at the same frequency to eliminate cross-talk distortion and maintain our signature sound in all applications.  The physical strength/size of the filter also allows us to offer true power factor correction for the typical 15A, 20A, and 30A circuit, providing an additional benefit and a lower noise floor.  The main difference between our models is the intended purpose, complexity of the network, and the frequency bandwidth.
