At my school we have a flight case with all our sound equipment in (and for some reason we still have a cassette player in there). Well last week we were talking about the connectors and cables we have. We don't really have spares for anything and lots of them are only held together with parcel tape. We currently use a PowerCon cable but their is already an IEC connector built in too. My question is : Should we get power rewired to the IEC connector (which we have plenty of cables for or just leave it with the PowerCon connectors. I prefer the PowerCon's because they lock and I grabbed a connector off the internet for about £5. I was also going to say that I don't know much about the sound system at my school so can I just dismantle an old extension cord and connect it up to the PowerCon connector or will I need a different fuse? I know its probably simple but I am still really a noob. And if you didn't notice from the £ I live in England and we have a ground on the plugs.
