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

TSA3120D is 2x30W 2 channels 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.

TSA3120D has a digital Input, Closed-Loop Class-D Amplifier chip TSA5756M and each channel has maximum 30W power output. Both of 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 coaxial input connector on the board which can accept different sampling rates digital audio source, from 16bit 44.1KHz to 24bit 96KHz. The highlight point is 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 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.

BVC port: Not support this function 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

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.

Following table lists all typical data of the Amp board. For full specification, please refer to the data sheet of TI's TAS5756M chip.

TA = 25 °C, fIN = 1 kHz sine wave, RL= 4Ω, VCC = 24V. (Unless otherwise stated)
