Hello again, well, i have bad news. The package arrived and the interface is not good, i wanted to buy it because of an odd cause: my own adj mydmx 3 interface was upgraded and doesn`t work with the old variants of my dmx2.1 and my dmx3 software wich are supported by my old two laptops (i did ramble about it in an older post on this forum) .So now i have a new question (should i make an entirely new post about it?...seems a good ideea...) anyway... The question is: How can i find the manufacturing date of a sealed in the box interface without unseal the box? Can this fact be hidden somewhere in a code on the carton box besides the rounded (silver ot white) sticker on the bottom of the interface itself? I ask that because there are a few sellers on local secondhand marketplaces which sell them new sealed at a price lower than in stores and they could have a new old stock (old variant) that i need. Thank you.
