2 x 100W SPDIF TOSLINK and DSP Audio Amplifier Board – TSA8802D

$64.50

TSA8802D 2x100W 2 channels SPDIF TOSLINK+DSP digital amplifier board with a TOSLINKBee receiver module. TOSLINKBee converts the SPDIF optical signal to an I2S signal and outputs it to the ADAU1701 DSP chip. TSA8802D is a very flexible DSP/DAC/Amplifier combination board. It has perfect class-D architecture(Based on TPA3221), and two channels have 100W power output. All the channels are capable of outputting nominal power simultaneously and continuously. Any DC12V-30V power supply can power this board. It can be used to drive any 3Ω,4Ω, or 8Ω passive speakers.

Any DC12V-30V power supply can power this board. It can be used to drive any 3Ω,4Ω, or 8Ω passive speakers. It’s a two-channel amplifier board. It has an optical input connector on the board which can accept different sampling rates from digital audio sources, 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 Sigma Studio. 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.

External Buttons port: This function does not support TSA8802D.

Volume control POT port: Ext POT port is 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.

  • ADC0- Main volume.
  • ADC1- Bass volume.
  • ADC2- Middle volume.
  • ADC3- treble volume.

DSP programming port: Users can load a new DSP program by using the USBi JTAG Sigma DSP programmer

The default DSP program can auto-select the Line in /SPDIF audio and output to the amplifier chips. SPDIF audio signal has higher priority.
