Might be more interesting to use music, something like what we actually listen to, to find out when/if the "nanny" protection kicks in? I don't actually listen to sine waves (or pink noise). This could also be useful for anyone who wants to leave the height channels on the internal amps, and offload the main 5 or 7 to an external power amp.Slow 'er down there Ace...Lol. Run this as loud as you dare until it triggers the protection Nanny. It's a 440Hz sine wave that won't be uncomfy to crank but it will draw power. See if this bad boy triggers.
I don't see at all why it matters at all if the amplifiers go into some kind of protection mode with high levels of pink noise or a sine wave. The only time I use pink noise or sine waves is when calibrating Dirac. More relevant when/if it goes into a protection mode with music (or a movie, whatever). This relates back to the cognitive dissonance mentioned earlier - those of us actually using the Pioneer seem mostly pleased with the audio, though I personally prefer an external amp at least for the main five channels.
