operating Instructions

after the power is turned on, the blue indicator light flashes and enters Blue tooth mode. After broadcasting the "prompt tone", enter the pairing mode and wait for pairing. Mobile phone Blue tooth search to" XY-P15W"( power amplifier board equipment name), click" XY-P15W"Connect, play" prompt tone "after successful connection, and the indicator light will be on for a long time to play mobile phone music, and the indicator light will flash slowly when playing music; After Blue tooth is disconnected, the power amplifier board is ready for the next pairing, and after playing the" prompt tone ", enter the pairing mode to wait for pairing. Connection as shown below

precautions for use:

1. Use the power amplifier board as far away as possible from WIFI signal (router)

2, the recommend power supply voltage DC 8~24V, more than 26V, the chip will burn.

3. The power supply shall not exceed 12V when connected to the 4Ω horn and 24V when connected to the 8Ω horn.

4. The power supply current recommend more than 2A.

5. The working power of the module exceeds 20W * 2, and heat sink is required.

6, the horn line should not be too long, to ensure that within 1 meter suitable

7. Pay attention to electrostatic protection. Before contacting the power amplifier board, you need to release the static electricity on your hand to avoid electrostatic breakdown of the chip. Blue tooth chip is more sensitive to static electricity.

8. It is recommended to adapt the rated power of the horn to 30W and above to avoid burning the horn.
