TSA8804 is a 4x100W Stereo Bluetooth 5 multipoint audio amplifier board. It has perfect class-D architecture(Based on TDA7498E) and each channel has maximum 100W power output. All channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC14V-36V power supply. it can be used to drive any 4Ω or 8Ω passive speakers.

The highlight point is BT 5 integrated. You can have many TSA8804 boards paired and work together. TSA8804 can remember the pairing info. You don't need pair them each time after you turn the amplifier board on. This make it possible to build a wireless surround sound system by using the TSA8804.

TSA8804 has a 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 have a debug port for Sigima Studio, User can program this module with our USBi programmer to get more functions which includes equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc...

If you only use one TSA8804. It can works like a common Bluetooth amplifier board. Power the amplifier board. Double click PAIR button to set the board into Pairing mode. Use your phone or PC (etc) to search for a new Bluetooth device. The module will appears as "TSA8804". You don't need a PIN, pair it and then you can play music.

Pairing buttons:

  • PAIR - Double click into pairing mode.
  • TX - Click into transimitter mode.
  • RX - Click into receiver mode.

 

One board works like a normal Bluetooth amplifier

 

Multiple boards work together

 

How to Use:

Master board:

  1. Power up the TSA8804, Blue LED slow blink. (Voice: Power ON)
  2. Double click PAIR button to set the TSA8804 into Pairing mode. Blue LED fast blink. (Voice: Pairing)
  3. Now, Your smartphone will be able to find a new Bluetooth device which name is "TSA8804". Connect it. (Voice: Pairing successful)
  4. You can play the music now. If you only use one amplifier board. You don't need do the following steps.
  5. Click TX button, Set the module to transmitter mode, Red LED ON.(Voice: Broadcast mode)

Slave board:

  1. Power up another TSA8804. Blue LED slow blink.
  2. Make sure master board already working correct and in transmitter mode. Click RX button to set slave board into receiver mode. It will auto searching the master board. Green LED ON (Voice: Broadcast audio enabled)
  3. Double click the RX button on the Slave board, double click the TX button on the Master board. The master board will auto searching(30s) slave board. Both master and slave board will be connected. (Voice: Pairing successful)
  4. The slave board will have music out now.
  5. If there have new board want join as slave board. Just click RX on new board into receiver mode then Double click RX, and Double click TX on Master module.
  6. If a slave board want quit. Click TX button on that module.

 

Note: If you don't hear the voice prompt when click TX . Please click the RX to switching the mode and then click TX again.

 

Output bridge enable settings:

TSA8804 is designed based on TDA7498E which means it can be used in stereo mode or mono BTL mode. You can set jumper closed to enable output bridge, then connect SPK1+ and SPK2+ together, connect SPK1- and SPK2- together, or connect SPK3+ and SPK4+ together, connect SPK3- and SPK4- together, the output becomes 200W.

 

Bridge the output

 

 

External volume control:

There have an Ext POT port on the board. You can connect external POTs (5K~20K) to control the Main volume,treble,middle,Bass. You need update the DSP program first. DSP program (with external POTs). This is our POT kit

  1. ADC0- Main volume.
  2. ADC1- Bass volume.
  3. ADC2- Middle volume.
  4. ADC3- treble volume.
