Description:

- 【High Performance】: The Bluetooth amplifier board features a powerful 2.1 channel and TDA7498E chip, delivers a massive 160W to both the left and right channels, plus a 220W for your subwoofer
- 【Versatile Inputs】: The power amplifier module features multiple input methods, supports AUX + Bluetooth + USB + App (dial button to switch modes and songs) inputs. The Bluetooth 5.0 provides a stable connection up to 15m/49 feet without obstruction
- 【Stereo System】: Experience superior sound quality thanks to an upgraded Bluetooth chip supporting MSBC/SBC decoding and large capacity energy storage capacitors that ensure stable power for clean, punchy bass
- 【Multiple Protections】: The amplifier board features a comprehensive suite of protection mechanisms, including safeguards against polarity, undervoltage, overheating, overcurrent, and short circuits. It is equipped with a quiet fan, maintaining optimal performance
- 【Note】: 1. Sufficient output power is only possible when the audio signal input is strong enough and the power supply voltage/current is high enough! The high the power supply voltage, the greater the output power; the lower the speaker impedance, the greater the output power. Please ensure that the power supply power is greater than the actual operating power of the amplifier! 2. Antenna and antenna base are not included
