Installation of hardware devices

① Remove the computer case from the computer. Accommodate the sound card to a vacant PCI slot. The latest motherboard usually has three types of slots which are the longest PCI Express 16x slot for graphic card, the shortest PCI Express 1x slot, and the PCI slot for the PCI sound card. The PCI slot has the same length with the PCI sound card so that users can easily locate the PCI slot. 

※Caution : For slim case, exchange the sound card with the provided LP type bracket, and then install. 




② Locate a PCI slot. Remove the empty guide from the computer case. The guide is usually inserted in a vacant slot. When installing an extension multimedia card, users are strongly encouraged to accommodate the sound card to a slot which is positioned one or more slot away from the graphic card.



③ Insert the sound card in a vacant slot. Slowly press the sound card after exactly aligning the bottom and the guide part of the sound card with the slot. Firmly press the sound card into the slot until it fits snugly, and then use the screw to secure the guide part and computer case.

※Caution : If the sound card is wrongly accommodated to the PCI slot, then the power is on, system including the sound card may cause severe damage.


④ After completing the installation of the sound card, place the computer case back on the computer, reconnect the power cable, and install the speaker. ※Caution : Users should use AMP-embedded speaker using power cable.
