Make sure your power source can deliver sufficient current to avoid audio stuttering, especially at higher volumes.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What speaker power rating is compatible with this amplifier board?\u003c\/h4\u003e\n\u003cp\u003eA: The XH-A158 outputs 5W per channel (5W × 2 stereo). For best performance and to prevent speaker damage, use speakers rated at or above 5W. Connecting speakers with a lower wattage rating at high volume may cause distortion or damage to the speaker.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I know the Bluetooth is connected and working properly?\u003c\/h4\u003e\n\u003cp\u003eA: When the board is functioning normally, the onboard Bluetooth LED indicator will flash at regular intervals. If the light stays solid or does not illuminate, there may be a connection issue with the Bluetooth module.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can the XH-A158 connect to a laptop or desktop computer?\u003c\/h4\u003e\n\u003cp\u003eA: Yes, it can pair with computers that have Bluetooth capability. If your PC fails to connect while a smartphone connects successfully, the issue is typically with the computer's Bluetooth driver. Uninstalling and reinstalling the latest driver version usually resolves this.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What power supply does the XH-A158 Bluetooth amplifier board require?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The XH-A158 amplifier board runs on DC 5V, making it compatible with standard USB power supplies and power banks.
