Yes, for piece of mind, there is circuity in the P5 to never allow the output of dangerous power to plugged in gear.
Thanks! Same for the P15 and P20?
Jamesh, many thanks! Glad to know it’s just a bit of confusion caused by the power interruption. My first incident may have triggered the P5 circuitry to which you referred, since I had no power flowing to components even though the P5 was fully on and the display functioning. The latter two didn’t, however, as I had power downstream even though the THD on the output exceeded 6% (presumably something that wouldn’t harm downstream equipment). Again, thanks.
