WillistonAudioLabs Posted September 29, 2013 Report Share Posted September 29, 2013 As I await my Amp Dyno, I decided to post some tests I did a while back. My setup uses power resistors, True RMS volt meter, 40Hz test tone and DD-1 to verify the 1% THD. I also show a Velleman HP50 scope to monitor the wave form. My test should simulate the "certified" mode on the AD-1 Amp Dyno...
