4 x 100W Class D Bluetooth 4.0 Audio Amplifier Board - TSA8498

Description

This is a 4x100W audio amplifier board with
AudioB plus
Bluetooth module. It's integrated 2xST high performance TDA7498 which support dual channel audio amplification. Each channel are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC14V-39V* power supply. Power input port can be power jack or screw terminal. The DC input jack is 2.5mm with positive core polarity, And if you use screw termail, Please pay attention on the polarity!
It has a smart cooling system, the fan not working in normal case to reduce the noise. Only start when the chip temperature > 65°C. Once the temperature goes down, the fan stop running.
It's perfect for your Hi-Fi application, the audio source can be RCA input or Bluetooth. Compatible with all Bluetooth devices that support media audio, including iPhone,Android. Let your smartphone paired with this board, play a music. So easy!
Note: We had tested it. It also works well with 12VDC power. But we suggest use DC14V-39V power if possible.
