Audio equipment is used in many occasions, but there will inevitably be some problems in use. How to deal with some problems?
1. The power indicator light is off
Solution: If this problem occurs, users should not be in a hurry. First check whether the power cord is plugged in properly, and whether the fuse in the machine box is intact? If the fuse is blown, a new fuse needs to be replaced; if it is intact, the user can check whether the lower line is loose or falls off. In some cases, these reasons will cause the power indicator to not light up.
2, the speaker has no sound
Solution: Some users report that there is no sound from the speaker. Many reasons are that the user did not unscrew the control button for the volume of the power amplifier. If the volume of the power amplifier is turned on, it may be because the line of the speaker is in poor contact, so there is no sound from the speaker.
3. There is no sound when inserting U disk or SD card
Solution: In life, many users put music in a USB flash drive or SD card for convenience, but some users report that when the USB flash drive or SD card is inserted, the speaker does not emit sound. The technical staff of the KTV bar-specific audio manufacturer recommends that the user check whether the music is updated to the root directory first, and the user can try another U disk, or format the U disk and then copy the music again.
4. There is a current sound when playing music
Solution: Some users report that there is a current sound or some noise when listening to music. The technicians of the KTV bar special audio manufacturer believe that the audio cable and the power amplifier player are not plugged in properly, or the line is in poor contact. The user can replace it with a new connection String.
5, the speaker has broken sound
Solution: Some users find that the sound of the speaker is a bit harsh when listening to music, and has lost its original sound. What should I do in this situation? The volume can be turned down.
