Why do Speakers have no sound?
- Please ensure the main power is connected and the power outlet is switched on.
- Please ensure the audio cable is properly connected and the input is set correctly on the speaker.
- Turn up the volume of the speaker or audio device.
- Turn the speaker off and restart it.
- Try another device for audio playing.
- Please contact customer service for further assistance.
How do I place my speakers properly?
Place the speakers on a solid and stable plane, the height of which should be kept at a position parallel to the listener's ears, and the distance between the bass reflex hole and the wall should be at least 20-50cm. To get the most accurate sound and balance, the listener's best spot should be on the axis of the equilateral triangle formed by the left and right speakers. At the same time, you can adjust the angle of the speaker slightly to obtain a more ideal stereo effect
Why my Speaker sounds unbalanced?
- Some audio devices or App have left and right channel volume balance settings. When the channel settings are unbalanced, it will cause the left and right volume of the product to be unbalanced or no sound on one side. When the volume of the left and right speaker is inconsistent or there is no sound on one side, please check whether the volume balance settings of the left and right channels of the audio source device or the App are normal;
- The sound difference may caused by the audio you are playing. Please try some softer and soothing tracks to test the product to see if it is normal;
- It may be that the audio device system is abnormal. Please check whether there is any software or system that needs to be updated on the device. Please try to update to the latest version and use it to see if it can return to normal;
- Please try to connect the product to other audio devices to see if it returns to normal. If it returns to normal, it may be that there is some unknown abnormality in the original device, which causes the left and right volumes to be inconsistent;
- Please make sure the connecting cable is firmly connceted between the active and passive speaker;
- If there is still a problem after all the above steps are checked, it may be caused by an abnormality in the product itself.
