High-pitched 'Whining' noise coming from my Code 50 power amp ~ should I return it? Settings: Amp volume on 0, Master volume at 6 or above ~ sounds like it could be an artifact of a failing Class D power circuit? I hope to hear from the Marshall moderators soon, before my 30 return window expires!
Thanks ~ Hadley in LA
Hi Hadley,
Thank you for your message, sorry you seem to having issues with your Code unit, we would recommend getting the amp looked at by an engineer to check what the issue is, we have not come across this before, we would recommend returning the unit to the dealer where you purchased the amp as the warranty is with them and they will be able to repair or replace the unit for you.
