The all-new micro iUSB3.0 represents the next generation of advanced computer audio technology featuring Active Noise Cancellation+; REclock; REbalance and REgenerate whilst still retaining and improving upon the original PowerStation/PowerStation+ which was at the heart of the success of its predecessor.
According to iFi, the micro iUSB3.0 addresses all significant USB audio problems that lead to poor quality computer audio by suppressing frame and packet noise present in the data stream, eliminating jitter and ground noise, correcting any impedance miss-matches and, last but not least, offering ultra clean power.
The noise floor of the micro iUSB3.0 has been improved upon and is an astonishing 0.1uV (or 0.0000001V). This is at the edge of what is measurable – even the Audio Precision analyzer only just about manages to measure the micro iUSB3.0, the company says.
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 revolutionary that the ANC technology is now a cornerstone of the ever-improving iFi USB audio technology range. 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. Measured noise drops by 100 times or 40dB in comparison to the common noise filters.
The micro iUSB 3.0 re-clocks/re-generates/repeats USB audio datastream. For any and every downstream DAC, REgenerate creates an all new USB signal and then employed a precision master clock with the REclock technology to completely eliminate computer jitter. USB signal is inherently a balanced signal, however most USB signals are unbalanced to some degree and contaminated by noise. By removing the DC offset and re-balancing the USB audio signal, it is now perfectly balanced and noise-free.
Being USB3.0 standard, the micro iUSB3.0 handles both USB3.0 and USB2.0. As audio signal quality improves, USB3.0’s ultra-speed bandwidth of 5.0Gbps offers an incredibly wide bandwidth that is 10x that of USB2.0’s 480Mbps. Hence, the micro iUSB3.0 handles ultra-high resolution audio without restriction.
The ground connection on the computer is contaminated with noise. The original micro iUSB cleverly solved this issue with IsoGround without falling foul of the USB standard (simply breaking the computer ground connection is NOT USB compliant and often results in USB connection problems). The new micro iUSB3.0 features not only this but also Auto/On USB power line options to further enhance the user experience.
With two sets of Dual-Ports, the micro iUSB3.0 operates as a computer audiophile-grade powered hub to serve two devices such as DAC and HDD. This means the whole complete computer audio is whisper-quiet as noise from one source does not contaminate another. With modern power-hungry devices, the micro iUSB3.0 is also Bus Charge 1.2 compliant which means it is able to fast-charge phones, tablets and even the phenomenal micro iDSD.
