Deathride Posted October 25, 2005 Share Posted October 25, 2005 ok I have a 24 core cable and im guessing I need to solder pins 2 and 3 from the solder side ... its an 8 in 4 out stage box that goes to 8 in 4 out stage box I have soldered pins 2-3 on both sides at the moment am I going wroung please help as this system has been sitting there doing nothing waiting for things to be done for the last 2 years so I really want to finish the system also dont know if this helps the system will be used for Mics and a talk back system the run is about 25 meters thank you in advance Link to comment Share on other sites More sharing options...
Andrew C Posted October 25, 2005 Share Posted October 25, 2005 Just to be 100% clear, it is a 24 way cable, with 24 screened pairs? If so, yes you join pin 1 to socket 1, pin 2 to socket 2 etc. Pin 1 is screen, pin 2 hot, & pin 3 cold. The info section on Canford's web-site has tables of standard colour codes depending on cable type. PDF of multi core colour codes Link to comment Share on other sites More sharing options...

Do you have 24 pair cable (i.e. 24 instances of a twisted pair of wires with an uninsulated earth "drain" wire each wrapped in an aluminium foil (a total of 72 insulated / bare earth wires ), or 24 core cable (i.e. 24 wires with an overall braided screen) or some other permutation? I'm guessing that with 12 connectors in use, you have 24 core overall screen cable? Is your problem determining what to do with the earth connection? If your cable is overall screen, then it's not recommended for this application. Most of the noise rejection comes from the cable pairs being twisted. Furthermore, without individual screening, crosstalk becomes increasingly problematic. Lastly, if by talk back, you mean running line level signals back to stage, you really do need individually screened twisted pair cable. If it is a comms system, (e.g. Tecpro) I would strongly suggest keeping the earth separate, as it is used for signalling. Let us know exactly what you are using, and we can go from there...

My next question is where can we get the right cable and how much will it cost. Thank you for confirming that I have not used the correct cable and also for your help in cable choosing the RIGHT cable .... the reason we had this is because an electrician said it was right and I always had my doubts about it we will be will to spend £150 approx on new cable if its on a drum Link to comment Share on other sites More sharing options...
Andrew C Posted October 25, 2005 Share Posted October 25, 2005 ok we have 24 separate wire NOT twisted pairs we have an overall braided cable .... by the sounds of this it is the wrong cable for the job ,,,, Wrong stuff! Is this for an installation, or a snake that gets coiled and moved?There is a huge choice, have a look here, for Canford Audio where FSM is an install cable that I have used and 'like' working with. If you need flexible then you might do well to look at Kelsey or Klotz. BTW, I hope you don't mind but with my hat on, I'm going to tidy that quote of yours!

paulears Posted October 25, 2005 Share Posted October 25, 2005 Canford cable prices are per metre. If the sound guys can't be bothered, why are you doing it. You'll only get the blame when it goes t*ts up. Link to comment Share on other sites More sharing options...

Jivemaster Posted October 25, 2005 Share Posted October 25, 2005 http://www.pearcehire.co.uk/files/pdf/second_hand.pdf Was a sale notified by JohnHuson in the "For Sale" section, There was some audio multi on there, used I think. Terralec.com sell stuff cheap but sometimes it is cheap stuff in the first place. Link to comment Share on other sites More sharing options...

BlueShift Posted October 25, 2005 Share Posted October 25, 2005 Id reccomend Kelsey's 12 pair 'UNI-12' audio multicore. I recently did an install where we have used over 500m of various lengths and sizes of kelsey multicore cable and I have had nothing but good results! more info here: http://www.kelseyweb.co.uk/products/Cable/...e_multicore.htm Link to comment Share on other sites More sharing options...
Deathride Posted January 9, 2006 Author Share Posted January 9, 2006 I apologise for renewing an old topic only now have we finally got funding for this little project the target is £250 for 100m of 12 pair cable what cable would you recommend and will it be balanced or unbalanced ( we want balanced because its easy to sort out ) I have gone to canford but as I have said before sound is over my head. this will hopefully be that last post also can you supply the link to the product I might be able to get more funding but I am fighting for this £250 !

audio Posted January 9, 2006 Share Posted January 9, 2006 It will be balanced if you use 12 pair cable and wire it right.... The one I have seen used for an install is :-http://www.canford.co.uk/commerce/productd...roductid=31-012 Link to comment Share on other sites More sharing options...
Rich newby Posted January 9, 2006 Share Posted January 9, 2006 Have you looked at Van damme cable. I have a multicore made up of it, I love it. Try it here, then you might get it cheaper with a google. It comes up to 1000m drums. May be over your budget still, but it is some of the best cable around.
