It has a digital Input, Closed-Loop Class-D Amplifier chip TSA5756M and each channel has maximum 30W power output. Both of channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC12V-24V power supply. it can be used to drive any 4Ω or 8Ω passive speakers.\u003c\/p\u003e\n\u003cp\u003eIt's a 2 channels amplifier board. You can pair it with a mobile phone or a computer (etc). Power the amplifier board. Use your phone or PC (etc) to search for a new Bluetooth device. The module will appear as \"TSA3121\". You don't need a PIN, pair it and then you can play music.\u003c\/p\u003e\n\u003cp\u003eThe highlight point is ADAU1701 DSP chip on board. It has a default DSP program loaded. Customers can adjust the gain, bass, midrange and treble in the DSP program.
