Ifi Micro IUSB3.0 User Manual

micro

1 & 3. USB Output (Power )

For optional iFi Gemini dualheaded USB cable or similar. Connect the USB connector labelled ' '.

Tip: Use the optional Gemini dualheaded USB cable for best sonics as this works on the same principles as physically separating the audio + power lines. Just like interconnects and power cables are completely separate in a hi-fi which system.

2 & 4. USB Output (Audio & Power )

For all standard USB cables where the lines are inside the same, one cable. Connec t the USB cable to this port at the 'A' connector. For the 'B' connector, attach to USB audio device (DAC, USB/SPDIF converter, USB interface etc).

Tip: For the first time, the micro iUSB3.0 has 2 sets of and ports so that it can be used as an active hub which cuts off noisy power sources and injects a new power supply for not one, but two USB devices such as USB DAC and USB HDD to run concurrently in the same, one setup.

Tip: For certain devices such as the iPad, where there is only a single USB output port, we recommend the Mercury cable as the audio + power lines are completely separate but are still within one cable construction.

Tip: The micro iUSB3.0 is Bus Charge

1.2 compliant which means it supplies a high-current to recharge even the most power-hungry devices (such as the micro iDSD) in the shortest time possible.

5. DC power input

Power the micro iUSB3.0 with only the iFi iPower, as without this unique audio power supply, the astonishingly low noise floor of

0.1uV(0.0000001V) of the micro iUSB3.0 would not be attainable.

6. USB Power Auto/On switch

For some users, they may wish to set this switch to ON, in which case, the iUSB3.0 will permanently supply 5V to the power line. This means that the computer will always 'see' a connec tion with the DAC and will never ‘drop’ the connection (which sometimes happens if the correct power off/on sequence is not adhered to for example).

This switch facilitates a more stable USB audio connection between the PC and the DAC.

During idle, the power consumption of the micro iUSB3.0 is very low so it is per fectly fine to be left on 24/7.

Otherwise, set to 'Auto' and it will function as per standard.

7. IsoGround®

This eliminates ground loops/noises caused by the PC.

Tip: For PCs without the earth pin, IsoGround® may not have an impact as the ground is not connected.

Tip: For the best performance, engage IsoGround® where possible. Disable if your USB device has trouble communicating with your computer.
