Thrill to the Full Sonic Potential of Your USB Audio Gear
Since its introduction in 2012, the original micro iUSB power filter for USB connections changed what was considered attainable from computer audio by supplying regenerated USB power. The recently launched flagship micro iUSB3.0 aimed at top-tier DACs costing over $5,000 is another leap for computer audio. And so is the new nano version for the rest of us.
The all-new nano iUSB3.0 is the 'Baby Bentley' of the flagship micro iUSB3.0. For DACS in the $500 to $5,000 price range, it retains the lion's share of the micro iUSB3.0's features. The USB3.0 chipset features all-original, cutting-edge USB audio technology drawn from AMR components, including Active Noise Cancellation® from AMR. The latest REclock and Rebalance circuitry work their magic, along with the original Regenerate, which was at the heart of the success of its predecessor.
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. ANC technology is now a cornerstone of the iFi USB technology range.
Air defense radar is transmitted at a certain frequency. When the signal bounces off the aircraft, a receiver on board the aircraft picks up the signal and a computer analyses its base frequency/modulations, and an identical, but out-of-phase signal is then generated to cancel out the enemy radar signal.
By generating a signal identical to the noise signal but in the exact opposite phase, ANC completely cancels all the incoming noise. ANC is the perfect 'antidote' for power supply noise, which is the bane of USB audio. With ANC the power line is filtered for RF noise. The measured noise floor of 0.5uV (0.0000005V) is at the measurement limit of the Audio Precision equipment.
Using ANC, the background and inner resolution to recordings is no longer hidden. Sonics are much smoother, just like how good analog should be.
A Whole New Signal: REclock / REgenerate
The nano iUSB 3.0 re-clocks, regenerates, and repeats the USB audio datastream. For any and every downstream DAC, REgenerate actually 'regenerates' an all-new USB signal via a precision master clock with the REclock technology to eliminate computer jitter. Music just flows better. It is cleaner, more accurate, and just like the real thing.
Recover the Unbalanced USB Signal with Rebalance
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.
USB3.0 Ultra-Speed 5.0 Gbps
iFi Audio products are at the cutting-edge yet also look to the future. The nano iUSB3.0 is USB3.0 standard and is backwards compatible with USB2.0. There is also the added sonic benefit from the USB3.0 platform which mandates better connectors, higher-quality cables, etc. 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.
USB Power 'On' for Less Stress
Unless the normal power up/down sequence is followed, the computer may 'lose' the DAC connection. The nano iUSB3.0 has an 'Auto/On' switch where the 'On' setting ensures USB power is constantly supplied to the PC, so it always 'sees' the DAC to enhance user enjoyment.
USB Dual-Ports for Dual-Headed Cable
Retaining the Dual-Port topology, the nano iUSB3.0 operates as a computer audiophile-grade USB power supply. The data and power lines are totally separate, which eliminates any cross contamination.
With modern power-hungry devices, the nano iUSB3.0 is also Bus Charge 1.2 compliant. It is able to fast-charge phones, tablets, and even its siblings, the nano iDSD and micro iDSD.
