Customer service sucks
you need to return it
it was B&W who handle Rotel and Michi product here in US but now they have a new distributor SUMIKO
according to the SUMIKO and my Dealer all the Michi P5 with 120V has affected with tone control issues and they’re going to start working on them this month AUGUST
your best Bet is contact your dealer And since you’re not original is complicated
we have Rotel Michi page in Facebook
you can check it out https://www.facebook.com/groups/384918068350254/?ref=shareAsk questions and actual owners may help you out
