Hi there. I have a new PL-IR and briefly tested it (just using app in and headphone out, if I remember correctly) before having to pause for a few weeks while attending to other priorities. While moving the unit, I noticed there is one Neutrik brand XLR jack on the back and two others that are not branded and have metal inserts, whereas the Neutrik does not.
I am just curious about why different brands were used and if this is normal. Sorry if this was not the proper place to ask, but I could not find anywhere else.
