Please tell me what software you use to perform the distortion measurement?
Thank you in advance.
Thank you in advance.
yes its REW...
meanwhile I finished the second amp 🥈 💪 and tested remote on-off function, particulary synchronisation of both. They are synced and timed via mains frequency, however the second one switches one cycle later as trigger is powered from the psu of first one. So there is difference of about 20-30ms but visually it looks like synced. (if you play the clip slowed down you can see the delay)
What is amazing, I was able to tweak soft-starting of both amps so they can start from same power outlet at once and not trigger breaker 🙂
also I managed to make balanced floating voltage divider and tried to measure THD vs Power. I think I am still limited by my gear capabilities as for source I am using focusrite solo and this amp wants rly high input voltage (2,5Vrms) but still measures nicely 🙂 maybe if I upgrade my soundcard I will update results in future...
below is thd vs pwr into 8R load (data below graph corresponds to minimal values ~45W)
