Good time to bring this up, I hope Joe will chime in because this is in the theoretical realm. With a PL 400 on the bench, I use my 8 Ohm 300 Watt resistors as dummy loads to measure the loaded output voltage of the amplifier. But if the amp has one of the DC protect boards installed, it will kick the amp off when I connect one of the dummy loads. As soon as I unplug the big power resistor, the amp comes back online. So naturally, the DC Protect board does not like the dummy load, but an 8 Ohm speaker is fine?
Thoughts?
