It may be a problem with the Bluetooth driver of the computer. The version is too old or there are files missing. It is recommended to uninstall and then install the latest version of the driver.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003e3.

The recommended voltage for power supply selection is 12V and the current is above 18A.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003eReason 2: If the power supply is okay, it may be that the power of the speaker is too small, such as outputting 200W, but connecting a 5W speaker. When the volume is turned up, there will be a stuck phenomenon, and the speaker may be burned.\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003e\u003cbr\u003e\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003e4. There is too much noise when playing music, or there is noise when not playing music?\u003c\/span\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"text-wrap-mode: nowrap;\"\u003eAnswer: The function of the power amplifier board is signal amplification. The main source of noise is the radio clutter in the environment that is amplified by the power amplifier board. Therefore, as long as the power amplifier board will have noise, it is recommended to select the audio cable with shielding function as much as possible It may be that the sound source is noisy, and normal mobile phones and MP3s will not. Most of them are on some old pre-boards, which are not compatible with our power amplifier board. You can add audio isolators or couple capacitors to test.
