[. . . ] Gemini 53dB noise reduction Reduction @ 120kHz (Radio stations) Overview Gemini can offer a complete solution for small entry level configurations to more sophisticated multiple component audio or audio visual entertainment systems. The Gemini features a sophisticated Delta filter network coupled with proprietary `Polaris-X' technology, which is based upon Kirchhoff's two current laws. [. . . ] These are very specialised in design as they must have minimal loss at mains frequency. IsoTek have found that `off the shelf' series filters are not able to offer sufficient bandwidth and flexibility that is required; it is for these reasons why we design and produce our own specification. These specialised components are made to the same standards as those used for British Aero Space applications. DELTA FILTERS A sophisticated type of Shunt filter which is connected across the three poles of the mains supply. The Delta filter is the most often described by text books as a practical solution for the worst effects of mains noise. It could be said that a Delta is three different types of shunt filter in one. MULTI LAYER DELTA FILTER For the ideal Delta filter you would use the perfect capacitor. The perfect delta arrangement for capacitors does not exist as all capacitors suffer from some inductance. The 'Multi Layer Delta Filters' work something like a loudspeaker crossover unit one section dealing with low (20KHz - 1MHz), the next medium and the final high radio frequencies. PROTECTION (FILTER) The protection circuitry will be understood by most people to offer valuable protection to their hi-fi equipment due to transient mains over voltage. IsoTek protection circuits offer a two fold operation, additional filtering, helping the shunt filters deal with high energy overload as well as component protection. [. . . ] ADAPTIVE GATING 'Adaptive Gating' auto senses the requirements of the load in a similar way to an iris of an eye adjusting to light. This system offers a universal system for both high current and low current devices and thus enables a continually fluid ultimate filtering environment. Gate works very well upt current levels (6A), howe gating allows 16A which sufficiant of domestic aud applications. [. . . ]
