Given my experience with A1 Evo, after changing the crossover the EQ filters will have to be re-calculated (and sometimes no solutions can be found). So if it let your change the crossover but does not perform additional calculation afterwards, it will be sub optimal.
There's a slider that allows you to adjust the crossover either globally or by speaker group. This is available under the "Bass Management" menu in Dirac and must be done before filter transfer to the RZ50 since it can't be changed in the AVR after the fact!
I've noticed something like this as well. Above 60 deg it limits power. Under that it seems to deliver full power in real content. It doesn't take that much for it to reach 60 deg though. After reading another post and trying it I also noticed it seems to recover the full power after it drops back below that temp.
It's quite possible that the latest firmware no longer requires unplugging the AVR and plugging back in to get out of limp mode. Now, it's simply on temperature permissive control!
I've pretty much been driven out of that thread. Looks like "evidence" is only valid if I was an actual RZ50/7100 owner.
That is pretty much what I experienced and also confirmed with a watt meter. As long as temps drops below 61c it seems to recover full power, pulling the plug may help the temp to drop faster.
It's possible or the temp was still above 60c when others had tested it thinking it would stay in limp mode until unplugged but maybe waiting longer would have brought it back out. Or it could react differently when benching it versus a more real world use.
I find it odd that some folks in AVS are praising how cool in temp the RZ50 is! I tend not to trust a Class A/B amp when it doesn't get a bit warm to the touch!
I feel like the power limiting is probably too aggressive. 60 deg c seems too low to start limiting power especially with the fan on LOW - just a few years ago Onkyo was allowing components run 80c+ with no heatsinks. I guess they didn't want so many failures this time around.
You might think so, but my previous generation Onkyo SR876 and Integra DTR70.4 got burning hot - and the heat was all on the processing boards/chips (HDMI, and DSP) - not on the power amp sections... which handled my difficult speakers without concern and without excess heat around the power amp heatsinks!!
Ah, you did the testing...
Not sure why the narrative in the AVS thread is completely ignoring the possibility that the over-temperature control IS causing the limp mode! Why is it impossible that a sudden surge of power requirement from low impedance also increases temperature?!!!
Only because there have been no other observations where temperature issues have coincided with limp/protection mode.... and that seems such an obvious combination that it seems almost beyond belief that the link has not been made before! (especially given that you can monitor the temperature via the web interface as well....)Not sure why the narrative in the AVS thread is completely ignoring the possibility that the over-temperature control IS causing the limp mode!

gregr is nearly at the conclusion that I've reached long ago but what he says is more well received so hopefully it gets to the logical conclusion eventually!
