TinySine TSA8800C Class D 2.1 TPA3221 DAC DSP ADAU1701 SPDIF 24bit 96kHz 2x100W + 200W 4 Ohm Amplifier Module
The amplifier module TinySine TSA8800C combines the functions of a 2.1-channel Class D amplifier, and a DAC / DSP with an SPDIFBee receiver converting the signal to I2S. It is capable of delivering up to 2x100W of power and features a 200W subwoofer output. To achieve this, it uses TPA3321 amplification chips. DAC / DSP signal processing is handled by an ADAU1701 chip, allowing tone adjustment for each channel. In addition to the SPDIF input, a stereo RCA input is also available.
The ADAU1701 DSP chip features a preloaded program allowing gain, bass, midrange and treble adjustment in the Sigma Studio DSP program/interface. A debugging port is available for Sigma Studio. To access advanced features, the user can program the TSA8800C via the TinySine USBi programmer. The available advanced functions include equalization, crossover, bass enhancement, multiband dynamic processing, delay compensation and more.
The TSA8800C amplifier module is powered by 12V-30V DC and can drive passive speakers with an impedance of 2Ω, 4Ω or 8Ω.

Description of the different ports
DSP input / output port
Three input / output pins are available for the ADAU1701 DSP chip: MP6, MP7, MP0. It is possible to develop a DSP program to meet different requirements. With the default firmware, if you connect these pins to GND, the TSA8800C will output a 1kHz sine wave.
Port for external buttons
There are three buttons on the module that can control the volume, play / pause, etc... It is also possible to connect external buttons using the dedicated port.
Pinout :
- P/P : play / pause button
- VOL + : volume increase and fast forward
- VOL - : volume decrease and fast rewind
- 3.3V
Port for potentiometers
External potentiometers (5K-20K) can be connected to the module to control the master volume, treble, midrange and bass. The DSP software must first be updated. A specially adapted potentiometer kit is sold separately.
Pinout :
- ADC0: master volume
- ADC1 : bass volume
- ADC2 : midrange volume
- ADC3 : treble volume
DSP programming port
The TSA8800C DSP detects both the Bluetooth signal and the RCA signal, but the default program gives higher priority to Bluetooth. If the Bluetooth signal is detected, the TSA8800C will output a Bluetooth audio source; otherwise, the RCA output will take over. It is also possible to develop a DSP program to meet different requirements, then load the new DSP program using the USBi JTAG Sigma DSP programmer (sold separately).
