30W/40W Stereo Bluetooth Power Amplifier Board 12V/24V High-Power Digital Power Amplifier Module XY-P40WItem NO.: XY-P40W

30W/40W Stereo Bluetooth Power Amplifier Board

Product Parameters:

● Product name: Bluetooth digital power amplifier board

● Product model: XY-P40W

● Working voltage: DC: 5~24V

● Bluetooth version: 5.0

● Transmission distance: 15 meters (visible and unobstructed)

● Number of channels: dual channels (stereo)

● Output power (@ 1KHz): 20W * 2 @ 12V 4 Ω, 30W * 2 @ 16V 4 Ω, 30W * 2 @ 21V 8 Ω, 40W * 2 @ 24V 8 Ω

● Adaptive horn (40W~200W): 4 ohms (5~16V power supply), 8 ohms (5~24V power supply)

● Module protection mechanism: power supply reverse connection protection, short circuit protection, self-recovery overheat protection

Note: The power supply voltage is relatively low but the output power is relatively large, which may cause "buzz" noise. Reduce the volume or increase the power supply voltage to solve the problem

Operating Instructions:

After the power is turned on, the blue indicator light flashes quickly to enter the Bluetooth mode; After broadcasting the "prompt tone", enter the pairing mode and wait for pairing; Mobile Bluetooth searches "XY-P40W" (name of power amplifier board device), and click "XY-P40W" to connect. After the connection is successful, the "prompt tone" will be played. The indicator light will be on for a long time to play mobile music, and the indicator light will flash slowly when playing music; After Bluetooth is disconnected, the amplifier board is ready for the next pairing, and after playing the "prompt tone", it enters the pairing mode and waits for pairing.

Precautions For Use:

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

2. The recommended power supply voltage is 5~24V DC. If it exceeds 26V, the chip will burn out.

3. The power supply shall not exceed 16V when connected to 4 Ω horn and 24V when connected to 8 Ω horn

4. The recommended power supply current is more than 2A.

5. The horn line should not be too long, and it should be suitable within 1 meter

6. Pay attention to static electricity protection. Before touching the power amplifier board, release the static electricity on your hands to avoid the chip being broken down by static electricity. Bluetooth chips are sensitive to static electricity.

7. It is recommended to adapt the rated power of the horn to 40W and above to avoid the burning of the horn
