Say Hii to another video in Roys Desk .In this Video I have Explained how a class D amplifier works and is it different from class AB amplifier. I have reviewed the TPA3116D2 based HW-715 board,with detailed sound testing and power testing.
It claims to be giving 80W + 80W .And in the end I have found out the actual max power that it can deliver. I have plotted the power output at different voltages for 4ohm and 8ohm load.
I have also given some tips on how to test a class D board which are having filterless design.
