TSA7802D 2x50W 2 channels SPDIF+DSP digital amplifier board with a TOSLINKBee receiver module. TOSLINKBee convert the SPDIF optical signal to I2S signal and output to the ADAU1701 DSP chip. TSA7802D is a very flexible DSP/DAC/Amplifier combination board. It has perfect class-D structure (Based on TPA3116D2) and 2 channels have 50W power output. All the channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC12V-24V power supply. It can be used to drive any 4Ω or 8Ω passive speakers.

It's a 2 channels amplifier board. It has a optical input connector on the board which can accept different sampling rates digital audio source, from 16bit 44.1KHz to 24bit 96KHz.

The main DSP chip on this amplifier board is ADAU1701. 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 Sigima Studio, and user can program this module with our USBi programmer to get more functions that include equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc.

 

External Buttons port:

Not support this function on TSA7802D.

 

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:

User can load a new DSP program by using the USBi JTAG Sigma DSP programmer

 

The default DSP program can automatically select the Line in /TOSlink audio and output to the amplifier chips. TOSlink audio signal has a higher priority.

 

Specification:

Specifications typical @ +25℃, Powered by 30V DC, unless otherwise noted. Specifications subject to change without notice.
