Z Filterpole Technology
Discover what many recording and film studios have known for the past 35 Years— MIT Z Filtration provides unparalleled AC power conditioning.
Q: What are MIT Filterpoles™ and what do the numbers mean?
A: Poles of Attenuation
(as referenced in The Impedance Domain)*
A properly built AC filter will not only attenuate unwanted noise on the AC power line, but it will also optimize the power factor.
The best way to attenuate unwanted noise is to create a very low impedance (a zero of impedance across the load which acts as an attenuation pole to the noise) surrounding the frequency (or frequencies) of the undesirable noise. In the case of audio, that would be at any frequency other than the power line frequency.
This is best accomplished by placing a tuned circuit in parallel, around the load.
MIT was awarded this patent in November 9, 1993: number 5,260,862.
Also important is the Power Factor which is a (dimensionless) number between 0 and 1. When power factor is equal to 0, the energy flow is entirely reactive, and stored energy in the load returns to the source on each cycle. When the power factor is 1, all the energy supplied by the source is consumed by the load and nothing is reflected back to the source.
MIT was awarded a patent on this technology regarding audio in July 13, 1993: number 5,227,962.
Q: What are problems are associated with typical series filters ?
A: Unlike MIT parallel filters, series filters :
A series filter operates by blocking, or rejecting certain types of noise. Imagine a series filter working by ‘shutting a door’ in the face of noisy pollutants. What happens to the noise after the door is closed? Since noise is energy, it cannot be destroyed; it must be consumed to be removed. So, when a series filter blocks or rejects unwanted noise, it simply reflects the noise right back to the source. The noise has not been removed, only reflected. This type of filter cannot rid itself of noise, as the noise is continually reflected between the series filter and the source, again and again. This is yet another source of audible noise, inserted by the very device called upon to eliminate it!
The Solution: Parallel AC Filtering
The Z Series of power products from MIT uses patented parallel “AC Filterpoles”™; a tuned LCR technology. MIT Z Filterpole technology eliminates reflections by efficiently absorbing all forms of AC noise from the mains, and then converting it into harmless thermal heat.
The result? Once the Z circuitry is working to clean, condition and protect your AV system, you will instantly enjoy “blacker” blacks, better color saturation, and increased shadow detail; movie sound tracks will deliver dialog, Foley sounds and background music with theater-like quality. Because your audio system now has a lowered noise floor, you will have pinpoint audio image placement within a lifelike soundstage, all with clear and authoritative bass.

Q: Why do I need Z Technology AC Power Conditioning ? A: Because you deserve the benefits.
Z Technology is the choice for Audio Expositions, Recording Studios, and the Movies
MIT Cables is often asked by High-End Audio Dealers and leading High-End Audio manufacturers to provide the supporting Speaker Interfaces, Interconnects, Power Conditioning and technology to “tie the individual components into a complete system”.
MIT Cables approaches cabling to properly interface components to operate as a single unit, or “System”. A System approach creates a single voice from many different contributors, similar to an orchestra or chorus made up of many voices. Similar to tuning an orchestra to a single perfect pitch, properly interfaced components can become more than the sum of its parts. We celebrate with our exhibit partners and all that contributed to creating the sonic experience at each of our collective venues.
MIT’s patented Z Power Filtration is requested and used by leading High-End Audio manufacturers to provide clean power to best showcase their components at every major Audio Exposition earning repeated “Best Sound”, “Best of Show”, “Best Sound of Show” awards over the past two decades. In addition to the High-End Audio industry, MIT Cables Technology has continued use with Grammy Award winning Recording Studios, and Academy Award (and multiple nominations) for Best Sound and Best Sound Effect Editing with Skywalker Sound. Skywalker Sound is the sound effects, sound editing, sound design, sound mixing and music recording division of George Lucas’ Lucasfilm motion picture group.
If you have seen an Academy Award movie over the past 20 years, you have already experienced: Oracle Technology – Multipole Technology – and MIT Z-Technology.
MIT Cables Technology IS available for you to gain the most from your audio and visual systems. Below are some examples of Show Awards and Recognition…
