USB 3.0 Interface

In order to improve the quality of the PC USB port through the data transmission and the noise level
of power supply, element H USB 3.0 INTERFACE is made to meet the high standard requirements of
Hi-Fi audio transmission and from source signal to bring a complete change.
Using the USB 3.0 bridge chip from Texas Instruments and a Crystek CCHD-575 super-low noise
femtosecond clock, which opens up an independent data channel for USB audio stream, by the
means of bypassing from the USB controller on the motherboard, directly bridging to PCI-E port, and
to avoid sharing the data channel with other USB devices.
The multiple filter units are integrated for USB power supply, which uses the heavy current LDO chip
with 6μVRMS and the solid-state capacitor, even if it's using the internal power supply, it can also
filter the high-frequency noise of PC switching power. The USB port can supply a maximum current
at 5V 1500mA for all audio devices supplied by the USB port, as well as the measuring function to
over-current and short circuit.
The two power supply (external/internal) modes can be configured through the switch on the
dam-board. With regard to the non-USB power supply audio devices, you can switch off the power
supply of the USB port.
The four-layer PCB with high speed circuit design standard, according with the differential on the
impedance standards and line length requirements. The CNC aluminum enclosure covers the entire
board, effectively shielded radiation interference from computer chassis, meanwhile taking into
account the cooling requirements of power supply chip.

4. Installation
To prevent the hardware damage, please unplug the computer power cable before installing the card. To
prevent static damage to the card, please release of static electricity before touch the card.
According to the specification of your own PC, you should use the attached dam-board with two
M3*6mm screws to fix it on the board enclosure.
Then choose the PCI-E x1 port on the main-board or PCI-E x4/x8/x16 port to install the board, while
fastening the screws and connecting SATA-15Pin power cable from PC power supply to the socket at the
rear-end of the board. (Not necessary for external power supply.) As shown below:

5. Driver installation
You can see the device name when your PC find the new hardware under the Windows7/8/8.1/10 system,
as shown below:
The driver can be downloaded automatically under Windows8/8.1/10 system.
If not, please visit www.matrix-digi.com to download the driver.
The driver not necessary for mainstream Linux OS.

6. USB power supply settings:
By sliding the switch on the rear panel of card can set the USB port power supply mode, this switch is a
three-position switch, as shown below:
OFF: Turn off the USB port output power, when the external DAC and other products do not need USB
bus power supply. In this mode, the devices such as USB flash disk which require USB bus power supply
will not be available.
INT: Internal power supply, USB bus power supply from SATA_15P port on the end of card, the input
power through the low noise LDO regulator and output from the USB port.
EXT: External power supply, USB bus power supply from the DC input port which on the rear panel of the
card, the power from DC input through the low noise LDO regulator and then output from USB port.

Precautions:
Some USB devices do not use the power supply from USB port, but it does not mean the bus power
supply could be unplugged, or it will cause the USB devices to malfunction.
Please disconnect your USB device before you change the power supply mode of element H. If you
switch the power supply mode when device is connected, the USB bus power supply surge may cause
the device to malfunction.
Make sure that the card is properly installed in the PC chassis and that the driver is installed correctly,
the hardware device is visible in the Device Manager after the driver is properly installed.
Use the internal power supply, please ensure that the SATA_15Pin connector on the end of the card is
properly connected to the power cable in the PC chassis.
Use an external power supply, please ensure that the DC input jack on the rear panel of card is proper-
ly connected to the external power supply and within the appropriate voltage range.
Make sure that the power supply mode switch on the rear panel of the card is in the correct position,
set to "INT" when using internal power supply, set to 'EXT' when using external power supply, and
'OFF' when no need power supply.
