X-Hi USB interface is designed for increasing the USB audio quality of computer. It increased the data transport quality and reduced the power supply noise, which make changes to your PC Hi-Fi system from the source.
X-Hi uses high precision clocks coordinate with USB 3.0 bridge chip from Texas Instruments, open up independent data channel for USB audio stream. It helps signal bypass the USB controller integrated in the motherboard, avoid sharing data channels with other USB devices.
X-Hi integrated multiple filter units for USB power supply, uses solid capacitors and low noise high current LDO chips. Even if use the USB internal power supply, it also can effectively eliminate the high frequency noise caused by the PC switching power. The USB port can supply a maximum current at 5V/1.5A for all audio devices supplied by the USB port. and can prevent devices from over current or short circuit.
There are internal and external power supply available, you can choose these kinds of power supply on X-Hi by sliding the switch on the panel. You also can turn off the USB bus power supply for the devices which has independent power supply.
With four-layer PCB of high speed circuit design standard, strictly in according with high-speed circuit design specifications. The circuit meet the differential pair impedance standard and the equal line length demand. The CNC aluminum chassis prevent the radiated interference effectively, giving consideration to the heat dissipation requirements of the power supply chip on board.
