TINYSINE TSA7802D, 2 x 50W SPDIF TOSLINK+DSP Audio Amplifier

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 Analog Devices ADAU1701 DSP chip. TSA7802D is a very flexible DSP/DAC/Amplifier combination board. It has perfect class-D structure (Texas Instruments 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.
