(DIY kit only,you need to solder the components by yourself. SMT resistances and capacitors have soldered on the board.)

This board is easy to build, there is no need to adjust or test.



Features:


1) Using TDA8920 chip, performance excellent
2) Digital ground (DGND) and Analog ground (AGND) are design in separation. Very small interference and sounds more pure.
3) The circuit layout are all circular arc. No 45°and 90°Inflection point. Sounds more mellow and full.
4) Using ERO capacitors in all the key points. Test performance is much better than the cpas of  WIMA.
5) Include the switch of Zero Dead Zone. Addition the function of current protection and UPC1237 protection.
6) The potentiometer can  install the RK27 or RK16,The price include the ALPS RK27.
7) SMT resistances and capacitors have soldered on the board.
