Product description New Design - Power Amplifier Board with Panel After countless days and nights of development, we have launched a 2.0 channel Bluetooth amplifier board with a panel, equipped with powerful TPA3251 chips, with a peak power of up to 220W+220W. When making a Bluetooth speaker, you no longer need to tedious measure the punching position. With this panel, you only need a few simple steps to DIY your Bluetooth speaker very easily. How to ground the panel? To reduce noises and interference, you need to ground the amplifier board. Grounding effectively reduces electromagnetic interference and electrical noises generated during the operation of the amplifier board. It also minimizes hum caused by ground loops, providing clearer sound quality and more stable performance. Multiple Input Methods This amplifier board is designed with multiple input modes, including Bluetooth, AUX, and USB, making it easy to connect to various audio devices such as smartphones, tablets, computers, music players, and televisions. This variety of connection options provides you with greater versatility and flexibility, allowing you to enjoy a higher quality audio input experience. The higher the input voltage of the power amplifier board, the higher the output power; The lower the impedance of the speaker you use, the higher the output power.If you want to achieve good power output, we recommend choosing a 24V 36V, 5-10A or higher power adapter.
