Bluetooth5.0 Power Amplifier Board Stereo High-Power Digital Megaphone Module 5-24V XY-P40W

Feature:

1. Adjustable volume: turn to the right to increase the volume, turn to the left to decrease the sound weight.
2. The power amplifier board has anti-reverse protection, short-circuit protection and over-temperature protection.
3. With Bluetooth function, the effective transmission distance is 10-15 meters (without obstacles).
4. The power amplifier module is small in size, stable in performance, and suitable for a variety of installation conditions.
5. The speaker power amplifier module can be used in home or car music systems to improve audio performance.

Package List:

1 x Power Amplifier Board

Note:

1. When the output power exceeds 20W x 2, a heat sink needs to be installed

2. The input voltage must be less than 26V, otherwise it will damage the Bluetooth power amplifier board

3. The power supply voltage is relatively low but the output power is relatively large, it may produce "zizi" noise, reduce the volume or increase the power supply voltageto solve the problem
