newbie desparate and running out of time

[saranam]

Hi I have scoured the net to get answers for this and I have sat for hours testing continuity and trying to work out this issue it is now 48 hrs to our next gig and my speakers are still in bits I hope someone can help here goes

 

Our front of house old peavey prosys15 speakers include 1x15 1x8 and 1xhorn

the passive crossover in one has blown I have replacements but the interfaces are different on the original there is a single connector with the 6 wires in that I have been trying to work out what is what

on the new 3 ways there are just +- in and loads of others but id dont know where to put all the wires from the input

here is what I know the

fig 1 red orange black and white are all on 1 side of the input PCB and have no influence on the other half

the yellow and blue are on the full range bi amp hi side and both link to the XLR yellow (+) is 1 pin blue is the other 2

the bi amp lo side

orange is + and is linked directly to white black and red are both - the PCB is split down the line between the red and blue

 

fig 2 orange and yellow are linked black blue and the empty pin next to the red are all linked the other empty sockets are UN-soldered on the rear of the board the white is not linked to any of the other wires here

 

fig 3 white is linked with yellow speaker wire

blue black and the empty pin next to the red are linked to the blue speaker wires on the mid and high but only on the red of the low

the blue speaker wire on the low seems to track from the speaker out through the larger of the chokes and link up to the red speaker out

 

beyond me can anyone fathom it for me

You need to re-post the question without all the font info. It's impossible to understand. Then if we can, someone will help out.

Calm down - 48 hours is a long time but you do need to post your questions clearly.

Welcome to the Blue Room :) Your post is incredibly hard to read (it looks like you copy-pasted from something)

 

But if you have 2 speakers, identical, and you have a replacement crossover board that is the same as the old one, are you able to open up the working one to see what the wiring is internally?

wont be long I have to go and undo that stoopid formatting you were right it was copied and pasted

You'll need to post the images. This may help you.

[saranam]

hi guys can you not see the images I uploaded them from dropbox and I can see them on post #1

I have a dropbox account and still can't see them. Try using photobucket or similar, or putting them in you public folder and putting the links up at least.

[Shez]

Your dropbox link (which only shows up in this page's source code) leads to a 403 error which says that one should log in to dropbox. As others have said, try photobucket as that works well here.

I don't understand this item:

Are you trying to replace the Peavey crossover with something from a different vendor?

hope this works from photobucket

So...

 

Full range audio goes into the Peavey on the XLR/Jack pair which then feeds all three drivers, via the x-over, unless something is plugged into the lower jack in which case the feed from the x-over to the LF driver is interrupted and fed from the LF jack.

 

The Yellow (+) and Blue (-) wires from the connector PCB is the input to the x-over.

 

The White (+) and Black (-) wires are the LF output from the x-over to the connector PCB.

 

The Orange (+) and Red (-) wires are the feed to the LF driver from the connector PCB.

 

 

However, the replacement x-over is a very different beast to the original. It looks to be from a stereo HF and MF with single LF driver setup. Given how few components it has it also would imply much lower cut-off slopes. I suspect that the two speakers will end up sounding very different to each other.
