ARC Ref 6 - Is it normal?


I got my ARC Ref 6 two weeks ago, and I use 3 pieces of Nordost Sort Kones BC to bring up my Ref 6 to test the sound.  But when I switch on the power-on button, my Ref 6's display show "Low Line Detected" for almost 20 seconds then it back to normal (Display show "Mute").  Is it normal ?   Will it show this everytime now? THX.

OP. So what was the final outcome of the Ref 6 problem or not electric or the Power conditioner. Would like to know.   Ref 6 owner too.
