iFi AUDIO iFi iPower 5V Power Supply

The central characteristic of iFi is in pursuit of the zenith in audio performance: it leaves no stone unturned. Well, the all new iPOWER is an exemplary example of this. Despite the fact that the iFi Ultra-Low Noise AC/DC adapter was exceptionally quiet and elevated the iUSB and iPhone to punch way beyond their respective categories, the all new power is even quieter, up to 10x quieter in fact. What is it? Brand new audiophile-standard DC-power supply:In 5V, 9V, 12V and even 15V versions. Which products is it aimed at? Virtually any DC powered device. Just check the correct voltage (5V/9V/12V/15V).Check the correct polarity Ensure the current output is sufficient, then plug in and enjoy. Advanced DC power design - the best has just been bettered Three years ago, iFi's Ultra-Low Noise AC/DC power adapter set the way and underpinned the whole iFi range from the iUSB to the iPhone leading to their loyal following.Well, not to rest on its laurels, iFi now has a completely new 'ground-up' DC powered supply. Active Noise Cancellation+ drawn from military radar technology Drawing from the military field (specifically the Thales Spectra radar cancellation system deployed in the French Dassault Rafale jet fighter), iFi adapted this technology to exclusively introduce the Active Noise Cancellation+ (ANC+) audio power system. It is so good ANC technology is now a cornerstone of the ever-improving iFi USB audio technology range. An air defence radar is transmitting at a certain frequency; the signal is bouncing off the aircraft; a receiver on board the aircraft picks up the signal and a computer analyses its base frequency/modulations and an identical, out-of-phase signal is generated by an onboard system to cancel out the enemy radar signal.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. What audio noise floor? Measured on the Audio Precision 2, the power has an astonishingly low audio band noise floor of just 1uV! To put this into context, iFi's very own Ultra-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. 12-Element Output Array Shaping 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. The 12-Element Output Array dynamically suppresses noise in real-time as it makes its way through the mains. Technology like this is quite simply unheard of in audio power design. Polarity Inverter Adapter for 'center negative' audio products At iFi, they like to think comprehensively and while the majority of home and pro audio products have a 'center positive' DC power connector type, if your product such as a guitar pedal or a Sony Discman has a 'center negative' instead of 'center 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 first as AMR/iFi is not responsible for incorrect use or damage arising from use of the power. Can be used globally; world-wide suitability AMR/iFi understands and appreciates that today, being portable and user-friendly is paramount. So the power is light, convenient and above all, easy to travel with and work in any country in the world. It comes in 5V, 9V,12V and 15V versions for all manners of DC powered devices and a set of interchangeable pins to span the globe: for USA/UK/EU/AUS electrical outlets. Performance and portability personified. In summary, all the technology behind the power would count for little if it was not audible.Well, it is both. With the all-new power, 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. Best of all, all existing iFi-powered devices all benefit and in the different DC-power versions, the power now compliments non-iFi DC-powered products too. So all can enjoy the "sound of iFi." Active Noise Cancellation+ Military radar techfor audio. Fighter jet tech to down USB noise. 10x quieter than before 1uV of audio noise, astoundingly quiet. Polarity Inverter Adapter For 'center negative'. Global supremacy on more than one level All Countries and all DC Voltages: 5V, 9V, 12V and 15V. Virtually silent noise floor of 1uV Even audiophile LPS is nowhere to be heard. Nobody does power better Pure PC power like no other.
