TSA7500- 2 x 100W + 200W 2.1 Channels Bluetooth Audio Amplifier Board
TSA7500 2x100W + 220W 2.1 channels audio amplifier board comes with AudioB pro Bluetooth module.
It has a perfect class-D architecture (based on TPA3221) and 2 channels have 100W power outputs and another one channel has 200W power output.
All the channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC 12V-30V power supply. It can be used to drive any 4Ω or 8Ω passive speakers.
TSA7500 can also be connected with our TSA1000, TSA1010 or TSA1020 external audio volume control board. Users can adjust the audio volume by rotating the real knob.
It is a 2.1 channels amplifier board. The channel for subwoofer has 200W mono output. You can pair it with a mobile phone or a computer with a Bluetooth function.
Power the amplifier board, use your phone or PC to search for a new Bluetooth device, the module will appear as “TSA7500”.
You don’t need a PIN, pair it up and then you can play music.
- TSA7500 can auto-detect the Aux in/Line in Audio input. Bluetooth Audio source has higher priority. When Bluetooth audio is paused or Bluetooth is disconnected, the amplifier will output the Aux in/Line in audio.
- There is an audio connector that can connect with an external DSP to set the subwoofer audio tones.
- BVC Port: BVC port can be connected with our Audio volume controller to control the Bluetooth audio volume.
Connect an external potentiometer control the subwoofer volume separately.
TSA7500 can auto-detect the Aux in/Line in Audio input. Bluetooth Audio source has higher priority. When Bluetooth audio is paused or disconnected, the Amplifier will output the Aux in/Line in audio.
TSA7500 + TSA1000, both Aux in and Bluetooth audio volume can be controlled through BVC port.
