iFi Audio iPower 12V Low Noise DC Power Supply w/ International Travel Adapters

The iPower is a new audiophile standard DC power supply. The iPower instantly improves performance with virtually any DC powered product. With the iPower you will hear your music or audio with more quality, detail, and clarity. It has been upgraded to be 10x quieter than than the previous iFi low noise power supply, 20 times quieter than conventional audiophile linear power supplies, and has been proven to be 1000x quieter than a standard stock wall warts. The iPower is compatable with virtually any DC powered device. Match the correct voltage, polarity setup, and ensure the current output is sufficient. The iPower has an astonishingly low audio band noise floor of just 1uV. With an 12-Element Output Array and 6-Element Input Array the iPower delivers audiophile-quality noise suppression. The noise floor is virtually inaudible and the all important level of refinement (whether listening to an analogue or digital source) has been amplified several notches. The iPower is light, convenient and above all, easy to travel with and works in any country in the world. iFi offers 5V, 9V, 12V and 15V versions for all manners of DC powered devices and each comes with a set of interchangeable wall plugs to span the globe: for USA/UK/EU/AUS electrical outlets. Active Noise Cancellation+ (ANC+)By generating a signal identical to the noise signal but in the exact opposite phase, it actively cancels all the incoming noise. ANC+ is the perfect 'antidote' for power supply noise, the bane of USB audio. With ANC+ the power line is filtered for audio band and RF noise. The measured noise floor of 1uV (0.000001V) is at the measurement limit of what even the most sophisticated Audio Precision equipment is capable of. Noise FloorMeasured on the Audio Precision 2, the iPower has an astonishingly low audio band noise floor of just 1uV! To put this into context, iFi's previous low noise AC/DC adapter was in a class of its own at 10uV. Compared to a typical audiophile Linear Power Supply which measured at 20uV, it is demonstrably clear AMR/iFi power supply technology is unparalleled. Dynamic noise suppression circuitry on Input and OutputShaping the face of technology, AMR/iFi not only pushes the boundaries of audio design, but power design too. After all, electricity is the 'fuel' behind the audio signal. There are two separate, but similar 'Array Technologies' in the iPOWER: 12-Element Output Array - is for addressing noise on the output (at the DC barrel) end.6-Element Input Array - is for dealing with noise at the input (at the 2-pin mains) end. What this means is that any noise is contained and neutralised with the iPOWER to halt it from contaminating the local mains or audio system. iFi is one of a handful of companies that manufacture 'battery quiet' DC power supplies. Just like hybrid technology in cars, both have come a long way in a short space of time and are gaining wider acceptance. Polarity Inverter Adapter for 'centre negative' audio productsAt iFi, we like to think comprehensively and while the majority of home and pro audio products have a 'centre positive' DC power connector type, if your product such as a guitar pedal or a media player has a 'centre negative' instead of 'centre positive' pin, it is important to use the iFi power inverter. If you are unsure of the DC polarity of your product, please check with your vendor. For equipment using a DC power connection, it is common practice to include protection circuitry against over-voltage/reverse polarity, but not every manufacturer will have applied this. Always check ...
