Designed to increase the USB audio quality of your computer, element H increases the data transport quality and reduces the power supply noise, upgrading your PC Hi-Fi system at the source.
The element H USB 3.0 interface is designed for increasing the USB audio quality of your computer. It increases the data transport quality and reduces the power supply noise, changing your PC Hi-Fi system from the source.
element H uses a Crystek CCHD-575 super-low noise femtosecond clock to coordinate with the USB 3.0 bridge chip from Texas Instruments and open up an independent data channel for the USB audio stream. This bypasses the USB controller integrated in the motherboard to avoid sharing data channels with other USB devices. That means a dedicated channel for unhindered audio performance.
The USB power supply of the element H integrates multiple filter units, 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 of 5V/1.5A for all connected audio devices. It can also prevent devices from overloading or short circuiting.
SATA power uses 12V and is required when USB devices are connected to the element H. Internal and external power supplies are supported on element H. Choose your power supply configuration by sliding the switch on the side panel. You also can turn off the USB bus power supply for devices that contain an independent power supply.
INT: Internal power supply - The element H will draw power for the USB device from the Sata 12V connection. The chips of the element H Card will still use 3.3V PCI-E bus power.
EXT: External power supply - The element H will draw power for the USB device from the external power source. The chips of the element H Card will still use 3.3V PCI-E bus power.
OFF: No power supply - The element H will stop outputting power from the USB bus. The element H card will still function. The chips of the element H Card will still use 3.3V PCI-E bus power. Do this when a USB DAC is connected to element H and does not need USB bus power. (These DACs provide their own USB bus power.)
Please note, although some USB DACs do not use USB bus power it still needs a 'device startup signal.' In this case, keep the SATA power connected to ensure that each startup can be successful, otherwise the USB DAC device may not be found. In that case you should use the 12v SATA power for your card.
With four-layer PCB of high-speed circuit design standard, strictly in according with high-speed circuit design specifications. The circuit meets the differential pair impedance standard and the equal line length demand. The CNC aluminum chassis prevents the radiated interference effectively, giving consideration to the heat dissipation requirements of the power supply chip on board.
NOTE: Please do not connect to the power supply with a voltage above 12V, or will cause damage. 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 for 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.
