View Full Version : Which cable to use.....
22-10-2003, 03:30 PM
I need a few opinions on some cable. The future planned speaker package could take on many forms (conection wise) and the main being XLR. So i will need to make some custom cables (pnono to XLR) to get em running, now the cable i have in mind is Belden 1508 (sheided twisted pair)and wodered if anyone has any expirience with this one or recomend another?
One set i have in mind will run on a phono conection but the other is balanced XLR, now is there any downside or harm that can come from feeding a balanced amp a un-balanced siganal and, if alls cool whats the best way of doing it?
I know Genelec do a active 8 channel balancer for ~£500 but, if it can be avoided all the better to me.

It's possible to use RCA to XLR, at the balanced end you wire as normal, then at the unbalanced you wire -tive and ground to the outershield of the RCA.
There is some debate as to what is the best way to wire up XLR connectors, but the above will work, even if it is not the best.
An active balancer (ATC make one as well, even more than the Genelec IIRC) probably isn't necessary unless you want to use really long runs of cable.

Thanks Mudge :thumbup:
I was hoping it would be all ok do it like that, and it opens up other options too :)~:-)~:smile:
Just need to know which cable to use and, maybe you might know this one mate but....... what is IDC termination? its on the the XLR's ive been looking at, it says no tools are requied ect so is it like some sort of cable clamp type thing.

IDC explained here:
In it's simplest form, think of connecting telephone wires to terminal boxes, ie., the wire sheath is cut when forced between the contact blades with the applicator tool.

I'm pretty sure Branxx recommended something from StudioSpares at about £2.49 a metre :D~:-D~:grin:, not sure which thread it was though, sorry.
As with all cables you can pay what you want, but at £2.49 you can't really go wrong! :lol:

I found some high quality Van Damme stuff at 75p a metre, trouble is you have to order it on 100m drums. :roll:
Still £75 for OFC individually screened multicore isn't bad - and it's kosha 110 Ohm suitable stuff too.

that dont sound too bad, about the same price as the 1508 i was looking at, i think what ever i get it going to end up being a drum of it. But i carnt find which one Branxx was saying about at studio spares, the cosest i found on there is a Quadflex (used to be starquad) one?

I found the thread, it was the 30K cable package one.

nice one mate, i just looked for the most exspesive one on there and it was the one branxx mentioned :thumbup: looks like a good contender :)~:-)~:smile:
I liked the idea of the belden but my main concern was that its only 3.3mm dia, even with its special foil, it just doenst seem right.
