Ultimate Noise-Fighting System for USB
The nano iGalvanic3.0 from iFi Audio is a ground-up design with full-galvanic isolation on USB3.0 and USB2.0. It is a through-an-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 nano iGalvanic3.0 is the ultimate one-stop USB enhancement solution for every computer audiophile.
The nano iGalvanic3.0 breaks ground loops and avoids noise-coupling in applications that require hi-speed USB transfers. It dramatically improves sonic performance and can be dialed into any computer audio system.
Double REclock2, REgenerate2, and REbalance2
Because USB is a bi-directional protocol, iGalvanic3.0’s provides unique double Regenerate, REclock, and Rebalance technologies before and after galvanic isolation. This ensures perfection transmission on both upstream and downstream. REgenerate actually 'regenerates' an all-new USB signal via a precision master clock with the REclock technology to eliminate computer jitter.
The USB signal is inherently a 'balanced' signal. However, most USB signals become 'unbalanced' to some degree and contaminated by noise. By removing the DC offset and 're-balancing' the USB audio signal using Rebalance circuitry, the signal is now perfectly balanced and noise-free.
5.0Gbps USB3.0 Superspeed
There is 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. Looking ahead, as audio transmission standards improve, with an ultra-speed bandwidth of 5.0Gbps, USB3.0 is future-proofed. It is 10x that of 480 Mbps on USB2.0.
The nano iGalvanic3.0 has a built-in super low noise-floor (0.5uV) audiophile grade USB power with Panasonic OS-CONs capacitors capable of beefy 900mA supply. For the best performance, this Stealth Converter is completely galvanically 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 optimzes isolation in systems where there is no, one or multiple Grounds(Earths) which cause hum and/or buzz.
The nano iGalvanic3.0 has Zero Delay highly advanced isolation technology, without any added conversion, processing, timing uncertainties, or delays. It is native, bit-perfect with minimal latency.
