TSA7499 is designed for amplifier manufacturers as well as DIY users. Bluetooth/LINE IN select switch and audio input port are designed with JST connectors. So, users can install this amplifier board in a box and connect an external switch and RCA/Mono plug to make their own audio amplifier.

TSA7499 can also connect with our TSA1000 external audio volume control board. People can adjust the audio volume by rotating the real knob.

This is a 2x100W audio amplifier board with Audio B plus  Bluetooth module. It has integrated ST high-performance TDA7499 chip which supports dual channel audio amplification. 

Both of the channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC12V-39V* power supply. 

It has a smart cooling system, so, the fan does not work in normal operation case to reduce the noise. The fan only starts when the chip temperature exceeds 65°C. 

It is perfect for your Hi-Fi audio application, the audio source can be cable input or Bluetooth. You may pair up the board with a mobile phone or a computer.

How to use?

Power up the amplifier board. Use your phone or PC to search for a new Bluetooth device. The module will appear as "BT Speaker". You don't need a PIN, it pairs up automatically and then you can play music.

Basic connection

TSA7499 with TSA1000 external volume control board

Note: We have tested it. We ship the board after full test. It also works well with 12V DC power. However, we suggest to use DC 14V-39V power supply if possible. 

If you connect a TSA1000 with this amplifier board the power input cannot be more than DC 24V. 

Specification:
