Looks like a REGA built-in safety feature to protect from an overheating problem caused by a grossly inadequate airflow needed to dissipate heat buildups ; requiring a repositioning of your amp in your rack setup .
I have the REGA OSIRIS integrated amp and the REGA ISIS VALVE cdp/ DAC , and their manuals requires a VERY healthy open spacing perimeter required around each unit, ….and NEVER EVER …..have anything stacked on top of either of them .
no service manual online - contact REGA directly .

BUT, AND IT’S A BIG “BUT” …. take it in to a pro tech to inspect it and give a pro assessment ….. there may very well be more mischief to it causing the overheating . You don’t want an embryonic fire hazard on your hands .
