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 iPhono 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 iPower 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/6-Element Input 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.
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 products
At 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 Sony Discman 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 first as AMR/iFi is not responsible for incorrect use or damage arising from use of the iPower.
Can be used globally; world-wide suitability
AMR/iFi understands and appreciates that today, being portable and user-friendly is paramount. So the iPower 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 iPower would count for little if it was not audible. Well, it is both. With the all-new iPower, 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 iPower now compliments non-iFi DC-powered products too. So all can enjoy the “sound of iFi.”
Got Raspberry Pi or similar? Then use the iPOWER 5v
The USB power line runs on 5v and the Raspberry Pi/Cubox/BeagleBone (or similar Microcomputer) is rapidly becoming the most popular computer server option. So, each iPOWER (5v version ONLY) ships with the DC > micro USB cable so that the iPOWER (5v) can supply pure, clean power to the microcomputer for the optimal computer audio playback.
The iDefender3.0® protects against the common problems of ground loop noise and noisy USB power:
1. Breaks noisy ground-loops. Significantly reduces system noise floor and makes for better dynamic contrast, warmth and resolution
2. Disconnects the USB Power from the PC and replaces it with a clean external power (optional iPower* 5V for ultra low noise)
3. USB3.0 port technology – most advanced and highest USB specification
To be used directly at the Source such as the PC usb port, it breaks ground loops and cuts the noisy USB power line. From computer audiophiles, musicians, home studio artists to pro audio customers, it improves audio playback quality at home and on-the-go.
For DACs that require USB power, to obtain the best sonic performance, the iPower 5V is recommended to supply the iDefender3.0®.
Break the noisy USB power, but in the correct way
power_ There are more than a few products that break the USB power connection, but of the ones known to us, they do very little because the noisy ground connection remains.
For DACs that do not use USB power (except for handshake) the iDefender3.0® breaks the ground connection eliminating earth loops, while allowing normal handshake operation to continue. So in terms of cutting out the noise, it does it in the most comprehensive way possible while at the same time, in an electrically correct way.
Need clean power? Inject iPower ‘quieter than battery’ technology
ipowe-ride As the iDefender3.0® breaks the noisy power supply, this is for DACs with an internally-powered USB line.
But for DACs that require use USB Power, a separate ‘micro port’ power connection is provided for a 5V DC supply. Any 5v power supply can be used. Though we recommend the almost silent 1uV noise floor of the iPower®. It is a new-breed of near silent DC-power supply; low power consumption and low-noise.
With 12-Element Array on the output and 6-Element Array technology on the input, there is next to no noise ‘supplied’ to downstream devices and ‘leaked’ back out to nearby components.
USB3.0 technology, at the cutting-edge
idefender_usb It is now a hallmark of all the latest iFi signal and power products to be USB3.0 standard. First USB3.0 is backwards compatible with USB2.0. Second, in terms of the specifications, USB3.0 is superior to USB2.0 e.g. the wire gauge specification is more exhaustive and the connections are better.
The iGalvanic3.0 is a ground-up design with full-galvanic isolation on USB3.0 and USB2.0. It is a through and through ultra audiophile-grade galvanic isolation device aimed purely at computer audiophile systems and nothing else.
“Galvanic isolation is a design technique that separates electrical circuits completely to eliminate stray or noise currents. Signals can pass between galvanically isolated circuits, but stray or noise currents, such as differences in ground potential or currents induced in AC power, are blocked.”
It is these stray currents that create noise in the system. Although iFi audio and others have created devices that kill noise, achieving galvanic isolation on USB3.0 is the ‘holy grail’ of computer audio. It has been sought by many but never actually achieved. Until now! The iGalvanic3.0 is the ultimate one-stop USB enhancement solution for every computer audiophile:
1. Audiophile-grade galvanic isolation.
3. Clean USB ultra power supply*.
• Breaks ground loops
• Avoids noise-coupling in applications that require hi-speed USB transfers
• Dramatically improves sonic performance
• Can be dialed into ANY computer audio system
The iGalvanic3.0 is the perfect solution for computer audiophiles through to recording studios seeking maximum sound quality from their USB digital audio system.
As USB is a bi-directional protocol, iGalvanic3.0’s provides unique double REgenerate/REclock/Rebalance before AND after galvanic isolation, this ensures perfection transmission on both upstream and downstream.
5.0Gbps USB3.0 Superspeed
No need to sacrifice USB transfer speed to enjoy the benefit of full galvanic isolation. With separate transmitting AND receiving lines, the USB3.0 is vast superior to USB2.0 at handling high data volumes.
Built-in super low noise-floor (0.5uV) audiophile grade USB power with Panasonic OS-CONs capacitors cable of beefy 900mA supply. For the best performance, this Stealth Converter is completely galvanic isolated too.
All computer audio systems are different. This is why the iGalvanic3.0 is dedicated for computer audio use and incorporates Ground Link (ISO, RF, DC-RF). A flick of the switch optimses isolation in systems where there is no, one or multiple Grounds(Earths) which cause hum and/or buzz.
A highly advanced isolation technology, without any added conversion, processing, timing uncertainties or delays etc.; native, Bit-Perfect with minimal latency.
