Power amplifier board use as far as poible away from WIFI signal (router)2. The recommended supply voltage DC 8~24V, more than 26V, the chip will .3. The power supply is not more than 12V when connected to 4 s speaker, and the power supply is not more than 24V when connected to 8 s speaker4. Power supply current is recommended to be more than 2A.5. The module working power exceeds 20W*2, need to add heat sink6. The speaker line is not too long, to ensure that 1 meters within the appropriate7. Pay attention to static electricity protection. Before contacting the power amplifier board, you need to release the static electricity on your hands to avoid static electricity breakdown of the chip.8. It is recommended to adapt the rated power of the speaker 30W and above, to avoid the heat ing of the speakerNote:The output power of the power supply should be greater than the output power of the amplifier, otherwise it will affect the sound quality. If the output power is greater than 20W and 20W, add heat sinkDue to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures.
