Sell 30W / 40W Stereo Bluetooth 5.0 Power Amplifier Board 12V / 24V High Power Digital Power Amplifier Module XY-P40W best price

Power supply: 5-24V DC / compatible 5.5-2.1 / 2.5 power interface Adapter speaker: impedance 4-8 ohms / power 40-200W Name: Bluetooth digital power amplifier board Model: XY-P40W Working voltage: DC: 5 ~ 24V Bluetooth version: 5.0 Transmission distance: 15 meters (visible and unobstructed) Number of channels: two channels (stereo) Output power (@ 1KHz) 20W * 2 @ 12V 4Ω 30W * 2 @ 16V 4Ω 30W * 2 @ 21V 8Ω 40W * 2 @ 24V 8Ω Adapter speaker (40W ~ 200W) 4 ohms (5 ~ 16V power supply) 8 ohms (5 ~ 24V power supply) Module protection mechanism: Reverse power 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 produce "zizi" noise, which can be solved by reducing the volume or increasing the power supply voltage. Instructions: After the power is turned on, the blue indicator light flashes quickly and enters the Bluetooth mode; after the "prompt tone" is broadcast, it enters the pairing mode and waits for pairing; the mobile phone Bluetooth finds "XY-P40W" (power amplifier board device name), click "XY-P40W" Connect, play the “prompt tone” after the connection is successful, the indicator light is on, you can play mobile phone music, the indicator light flashes slowly when playing music; after Bluetooth is disconnected, the amplifier board is ready for the next pairing, and the “prompt tone” is played Pairing mode is waiting 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 DC 5 ~ 24V, if it exceeds 26V, the chip will burn. 3. The power supply does not exceed 16V when connected to a 4Ω speaker, and the power supply does not exceed 24V when connected to an 8Ω speaker. 4. The power supply current is recommended to be above 2A. 5. The speaker wire should not be too long, ensure that it is suitable within 1 meter 6. Pay attention to electrostatic protection. Before touching the power amplifier board, you must first discharge the static electricity on your hand to avoid the static electricity from puncturing the chip. The Bluetooth chip is more sensitive to static electricity. 7. It is recommended to adapt the rated power of the speaker to 40W and above to avoid the speaker burning and burning Package: 1 x Power Amplifier Board
