Frequently Asked Questions

• Q: Why can’t I find Bluetooth?
  A: The input channel must be switched to BT to search for a connection to Bluetooth

• Q: Why does music stutter when using Bluetooth?
  A: The effective transmission distance of Bluetooth is 1 OM without blocking. If it exceeds 10 M or there is obstruction, the transmission distance of Bluetooth will be affected

• Q: Will my speakers burn out if I have a speaker below 100W?
  A: No, the maximum output of the amplifier is 120W, which means the sound is set to the maximum. If the speaker is low in power, just turn the sound down

• Q: Why does the speaker have so loud current noise?
  A: If you are not using the power supply from the factory originally, please replace the power supply before testing. Many power sources in the market have high interference factors which will cause high current sound.

• Q: Why do I plug in the input line and not connect to the sound source, the sound box will have a big buzz.
  A: When the signal line without shielding is not loaded, there will be an interference signal in the amplifier for amplification. If you hate this sound, it suggests you replace the signal line with shielding or unplug the signal line.

• Q: Why is it that the volume of the machine remains the same with different sound sources (such as a CD and a cell phone), but the volume is different?
  A: Different devices output different electrical signal amplitudes, such as mobile phones are usually 0.35mV, and CDS are 1V., then the sounds are of different

• Q: Why is there no sound when PC-USB is connected to the PC?
  A: Please follow the PC-USB operation steps first to confirm whether the digital playback output is selected. If you still have no sound, you can restart the computer and repeat the operation again
