AFAIK all of the drivers in the box are 8 ohm, well not too sure about the HF but the mid and LF drivers are for sure. Binning off the crossover entirely and running on an NL8 was my other possibility if I couldn't get these to work, but I've already bought all the cabling and installed dual NL4 cnc cut panels on the back with connectors and wired them up, and running 3 way would need I would need to buy another amp and another bigger amprack to fit it all in, and would mean all the work I had done so far was useless which wouldn't be ideal! But ive got to the frustration level point right now where I was about to rip all the x-overs out, yes |

I did think this originally but after sourcing the wiring diagrams from EAW it shows to be an earth! |

I think the best thing you could do is not use the words "live, neutral and earth" at all when working on or discussing a passive speaker. The panel clearly says "monitor"on pin 7 , why are you calling it "earth"? your just confusing yourself and others.

Alright mate he's only asking because he doesn't know... And if there is a diagram saying it's an Earth then it's probably worth asking .
I suspect you should ignore the diagram, I actually wrote down the wiring colours I used but I'm 200 miles away from the boxes and can't confirm whether this is wiring I attached or wiring from the box. I think its the wiring already in there as we have Yellow. I also did some tests to check I had the correct phases but I can't remember what. Anyway ->
LF Black negative LF Blue Postive HF Black negative HF White Postive Yellow Monitor |

All good , just to finish off ,in a John Cleese voice "I dont want anyone to connect the yellow wire to anything ,and I want to make this absolutly clear ...even if they do say johovah"

They might actually have a "ground". Since they were installed at a stadium, they might have "earth" to protect the system from lightnings.

Why yes, how else could they get them to be struck by lightening ,perhaps thats why they removed them?You could use these under ground without an earth I suppose , it occured to me that maybe the monitor out on pin 7 is composite video?...................................Jehovah

Thanks mate! I had the yellow and the white confused and that was where my issue is. I originally cut off the white thinking it was a redundant earth when i should have cut off the yellow. The diagrams from EAW show an earth. And the socoplex cables that plugged into them had 6 black cables and a yellow and green cable (which must have been monitor) which is the colour for earth in UK which is where I got confused, went through a massive ballache setting up a trade account and signing an NDA to get the stuff aswell. Have the whites still inside the cab and its all done with choc-blocks so easy procedure to switch it all over :) |

Good advice, brain wasn't functioning correctly after stressing out about the whole thing for a fairly long period of time, and getting lots of different people tell me very different things!
