4 x 100W Class D Bluetooth Audio Amplifier Board – TSA8498
This is a 4x100W audio amplifier board with AudioB plus Bluetooth module. It’s integrated with 2xST high-performance TDA7498, supporting dual-channel audio amplification. Each channel is capable of outputting nominal power simultaneously and continuously. Any DC14V-39V* power supply can power this board. The power input port can be a power jack or screw terminal. The DC input jack is 2.5mm with positive core polarity, And if you use a screw terminal, Please pay attention to the polarity!
It has an innovative cooling system. The fan does not work in standard cases to reduce the noise. It only starts when the chip temperature > 65°C. Once the temperature goes down, the fan stops 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 be paired with this board, play music. So easy!
- MUTE: Connect MUTE pin with GND pin. The amplifier board will go into a mute state.
- STBY: Connect STBY pin with GND pin. The amplifier board will go into a standby state to save power.
- B/A: Connect B/A pin with GND pin. The Bluetooth input will always be the audio source, selecting switch position, no matter the audio source.
Note: We have tested it. It also works well with 12VDC power. But we suggest using DC14V-39V power if possible.
