It is actually just a one off for my little PA system but I always like to think "What if i want to make let's say a hundred and use it by myself" and try to design it accordingly.
The first thing i thougt of was an default IP adress and just a simple button to be able to set it to default again. But then i thought what if you have 10 of these in a rack wired up and want to setup. So DHCP would be the right choice. But i think i don't i get how do you mean it. Does the AMP act as a dhcp or the Notobook from where you try to setup ?
WIFI and Bluetooth is pretty much ruled out. I don't like wireless in such enviroments and i'm not sure if my current desing is able to handle one or maybe both of them hardware wise
Edit to DBecker : Those NFC EEPROMS look very nice
never heard of them before. Defnitely worth experimenting with
