TSA8802D 2x100W 2 channels SPDIF TOSLINK+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. TSA8802D is a very flexible DSP/DAC/Amplifier combination board. It has perfect class-D architecture(Based on TPA3221) and 2 channels have 100W power output. All the channels are capable of outputting nominal power simultaneously and continuously. This board can be powered by any DC12V-30V power supply. It can be used to drive any 3Ω,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 have a debug port for Sigima Studio, User can program this module with our USBi programmer to get more functions which includes equalization, crossover, bass enhancement, multiband dynamics processing, delay compensation, etc.

Volume control POT port:
There have an Ext POT port on the board. You can connect external POTs (5K~20K) to control the Main volume,treble,middle,Bass. You need 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:
User 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.
Specification:
