2 x 30W SPDIF TOSLINK+DSP Digital Audio Amplifier Board – TSA3120D

$42.85

TSA3120D is a 2x30W, 2-channel SPDIF+DSP digital amplifier board with a TOSLINKBee receiver module. TOSLINKBee convert the SPDIF signal to I2S signal and output to the ADAU1701 DSP chip. It has a digital Input, Closed-Loop Class-D Amplifier chip TSA5756M and each channel has a maximum 30W power output. Both channels are capable of outputting nominal power simultaneously and continuously. Any DC12V-24V power supply can power this board. It can be used to drive any 4Ω or 8Ω passive speakers.

2 x 30W SPDIF TOSLINK+DSP Digital Audio Amplifier Board – TSA3120D

TSA3120D is a 2x30W, 2-channel SPDIF+DSP digital amplifier board with a TOSLINKBee receiver module. TOSLINKBee convert the SPDIF signal to I2S signal and output to the ADAU1701 DSP chip. It has a digital Input, Closed-Loop Class-D Amplifier chip TSA5756M and each channel has a maximum 30W power output. Both channels are capable of outputting nominal power simultaneously and continuously. Any DC12V-24V power supply can power this board. It can be used to drive any 4Ω or 8Ω passive speakers.

It’s a two-channel amplifier board. Its coaxial input connector can accept a digital audio source with different sampling rates, from 16bit 44.1KHz to 24bit 96KHz. The highlight point is the ADAU1701 DSP chip on board. It has a default DSP program loaded. Customers can adjust the gain, Bass, midrange, and treble in the DSP program. It also has a debug port for Sigma Studio, and the user can program this module with our USBi programmer to get more functions, including equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc.

BVC port: This function is not supported on TSA3120D.

Volume control POT port:

There is an Ext POT port on the board. You can connect external POTs (5K~20K) to control the Main volume, treble, middle, and Bass. You need to update the DSP program first. DSP program (with external POTs). This is our POT kit.

  1. ADC0- Main volume.
  2. ADC1- Bass volume.
  3. ADC2- Middle volume.
  4. ADC3- treble volume.

DSP programming port: The USB JTAG Sigma DSP programmer allows users to load a new DSP program.

The following table lists all typical data on the amp board. For full specifications, please refer to the datasheet of TI’s TAS5756M chip.
