TINYSINE TSA7802B Amplifier Module TPA3116D2 Bluetooth DSP

TINYSINE TSA7802B: TPA3116D2 amplification chip

The TinySine TSA7802B is a two-channel 2x50W DSP amplifier module equipped with an AudioB I2S Bluetooth module supporting the aptX codec. It combines a DSP, a DAC and an amplifier for maximum flexibility. The amplification is based on a Class D TPA3116D2 chip, and has two output channels each delivering 50W at 4 Ω. The power supply range of this module is 12V to 24V DC and can be used to drive any 4Ω or 8Ω passive driver.

TINYSINE TSA7802B: ADAU1701 DSP chip

The DSP part of the module is based on an ADAU1701 chip, with a default program already loaded. With this default program, you can adjust the gain, bass, midrange and treble of your music. Furthermore, if you wish to program the module yourself to include your own functions, all you need to do is use Tinyside's USBi programmer, enabling you to include functions such as crossover, bass enhancement, multiband dynamic processing, delay compensation and so on. Furthermore, the TSA7802B module includes a Bluetooth chip compatible with the Apt-X codec and True Wireless Strereo (TWS).

The module's external button port enables volume control and pause/play. You can connect buttons simply by referring to the silkscreen on the back of the module. Furthermore, you'll have access to the volume control port, to which you can connect a potentiometer kit (5K~20K) that lets you control total volume, as well as bass, midrange and treble. To do this, you'll first need to update the DSP program (file available in the Download tab), then make the connections as follows:

• ADC0 : Volume total
• ADC1 : Volume des basses
• ADC2 : Volume des médiums
• ADC3 : Volume des aigus
