2 x 100W Class D Bluetooth Audio Amplifier Board - TSA7499
Product Code: G5799C357677C5
Product Description
TSA7499 is a 2 x 100W audio amplifier board with AudioB plus Bluetooth module. TSA7499 are designed for factory or DIY users. 

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

Bluetooth/LINE IN select switch and audio input port are designed as 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. 

It has integrated ST high performance TDA7499 chip which supports dual channel audio amplification. Both channels are capable of producing nominal output  power simultaneously and continuously. 

This board can be powered by any DC 14V-39V* power supply. It has a smart cooling system, the fan does not work in normal case to reduce the noise. It only starts when the chip temperature exceeds 65°C.

It is perfect for your Hi-Fi application, the audio source can be both Aux input or Bluetooth. You can pair it with a mobile phone and play audio. 

Power up the amplifier board, use your phone or PC (etc) to search for a new Bluetooth device. The module will appear as "BT Speaker" on your phone.

You don't need a PIN code, simply pair it up and you can play your music.
Basic connection
TSA7499 with TSA1000 external volume control board
 
Note: We have tested it. It also works well with 12V DC power. But we suggest you to use DC 14V-39V power if possible.

Note: If you connect a TSA1000 with this amplifier board, the power input should not be more than 24V DC.
