Maintenance Knowledge 1. Correctly set the sound card output mode. Generally we use the integrated AC97 sound card, the back panel of the chassis has 3 interfaces, we normally use are active speakers, so should be plugged into the line output of the interface (green), and the red interface is connected to the microphone, and the other is the line input (analog input) interface (blue).
Maintenance Knowledge 2. When powering on, shutting down, restarting, etc., the speaker volume should be turned off to a minimum or power off to prevent damage to the speaker by large current.
Maintenance Knowledge 3. Do not make the speaker long working volume, on the one hand on the human hearing is not good, in addition easy to burn power and amplification circuit.
Maintenance Knowledge 4. Pay attention to the placement of the speaker. The correct method should be: The display as the center, left and right symmetrical placement, and to ensure that speaker speakers are on the user, the direction of the subwoofer is not strong, the position can be flexible; for the speakers that often use large volume, do not put the speaker directly on the computer table (especially the subwoofer), in order to avoid resonance with the computer table distortion At the same time the larger vibration on the high-speed operation of hard disk, optical drive is also harmful.
