So I pulled my new Denon AVR X3400 out of the box tonight. Doing the normal scan to make sure there is no damage, and I noticed what I thought was a loose bread tie laying inside on one of the silver support brace. However it looks like it’s maybe soldered to a circuit board and then laying on the brace. I did a google search and from what I see it looks like maybe this was meant to be there. But it’s hard to see in pics. Any help? Any suggestion to what this is or if it’s normal on this model?
