TSA7802B 2x50W 2 channels Bluetooth+DSP amplifier board with an AudioB I2S Bluetooth module that supports Apt-X. TSA7802B is a very flexible DSP/DAC/Amplifier combination board. It has perfect class-D structure (Based on TPA3116D2) and 2 channels have 50W power output. All the 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.
It'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 "TSA7802B". You don't need a PIN, pair it and then you can play music.
The 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. It also has a debug port for Sigima Studio, and user can program this module with our USBi Programmer to get more functions that include equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc. TSA7802B supports Apt-X and TWS. Therefore, Users can stream audio to 2 paired amplifier boards at the same time wirelessly.
Volume control POT port:
There is an Ext POT port on the board. You can connect external POTs (5K~20K) to control the Main volume,treble,middle and Bass. You need to update the DSP program first. DSP program (with external POTs). This is our POT kit
