2 x 100W + 200W 2.1 Channels Bluetooth+DSP Audio Amplifier Board – TSA8800B Apt-X

$76.45

TSA8800B is a 2x100W + 200W 2.1 channels Bluetooth + DSP amplifier board with an AudioB I2S Bluetooth module supporting Apt-X. TSA8800B is a very flexible DSP/DAC/Amplifier combination board. It has perfect class-D architecture(Based on TPA3221) with two channels capable of a 100W power output and another channel boasting a 200W power output. All the channels are capable of outputting nominal power simultaneously and continuously. Any DC12V-30V power supply can power this board. It can be used to drive any 4Ω or 8Ω passive speakers(The subwoofer channel can drive 2Ω speaker).

It can be used to drive any 4Ω or 8Ω passive speakers(The subwoofer channel can drive 2Ω speaker).

It’s a 2.1-channel amplifier board. That channel for a subwoofer is 200W mono output(Users can change the DSP program to let it become a right or left channel or mixed output). 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 “TSA8800B”. You don’t need a PIN, pair it, and then you can play music.

The highlight point is the ADAU1701 DSP chip on board. Users can set each channel’s audio tones separately. Apt-X and TWS supported. Therefore, users can stream audio to 2 paired amplifier boards wirelessly.

DSP I/O Port: We provide 3 I/O pins of ADAU1701 DSP chip for use: MP6, MP7 and MP0. Users can develop DSP programs to fulfill different requirements. If you connect these pins to GND for the default DSP firmware, TSA8800B will output a 1kHz sine wave.

External Button Port: Three buttons on the board can control the audio volume, play/pause, etc. These ports allow you to connect external buttons easily.

Pins definition: (Check the board backside silkscreen):

  • P/P: Play pause button
  • VOL+: volume increase and forward button
  • VOL-: volume decrease and rewind button
  • 3.3V

Potentiometers Port:

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.

  • ADC0- Main volume.
  • ADC1- Bass volume.
  • ADC2- Middle volume.
  • ADC3- treble volume.

DSP Programming Port:

TSA8800B’s DSP detects Bluetooth and RCA signals, but the default program gives Bluetooth a higher priority. TSA8800B will output a Bluetooth audio source if a Bluetooth signal is detected. Otherwise, it will output an RCA audio source. You can develop a DSP program to fulfill your requirements, then load the new DSP program using the USBi JTAG Sigma DSP programmer.

Two boards work in TWS mode. You can also build a wireless subwoofer system.

  • S1 – Long press 3s into pairing mode. Long press 6s to clear the pairing info.
  • S1+S2 – Long press 1s into TWS slave mode.
  • S1+S3 – Long press 1s into TWS master mode.
  • S2+S3 – Long press 1s disconnect TWS connection.
