1 x 200W DSP Mono Audio Amplifier Board - TSA7551A
20 or more $42.00
TSA7551A is a 200W DSP mono amplifier board, it's a very flexible DSP/Amplifier combination board. It has perfect class-D architecture(Based on TDA7498E) and the mono channel has 200W power output. This board can be powered by any DC14V-39V power supply. It can be used to drive any 3Ω,4Ω or 8Ω passive speakers. TSA7551A has a smart cooling system, the fan not working in normal case to reduce the noise. Only start when the board overheat.
It's a one channel amplifier board. The only channel are 200W mono output(right and left channel audio mixed in the DSP program). Connect audio source to audio input jack, power the amplifier board then you can play music.
TSA7551A has a 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...

Comparison of differences between TSA7551 and TSA7550
External Button port:
Not support this function on TSA7551A.
Potentiometer 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. 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
Specification:
Specifications typical @ +25℃, Powered by 36V DC, unless otherwise noted. Specifications subject to change without notice.
