DIY your own balanced interconnect

DIY your own balanced interconnects with Mogami Neglex 2534 !

Neutrik XLR plugs, Mogami 2534 cable, paper cutter, Kester 44 solder and Teflon plumbers tape


The Mogami Neglex 2534 is a flexible shielded star quad cable, i.e. separate shield and four individually insulated conductors. I have used this cable in both single ended and balanced applications, and this cable really shines in balanced form. Singapore readers can get this cable from Team 108 in Macpherson. You can have a look at their website for contact details and opening hours,  http://www.team108.com/

Once you have cut your cable to length, slide the rear plug housings on to the cable. I have lost count of the number of times I have soldered cables happily only to realise that I forgot the backshell !

Strip the cable and conductors, and twist the same coloured conductors together, i.e. form two conductors by twisting the clear cables together, and repeat with the blue cables. Bundle the shield wires together too.



I would suggest tinning the cable ends once you are done.



For plugs, general convention is male on one end, and female on the other. Check your equipment to be sure - I've seen some funky equipment that do not follow this.

Solder the shield to pin 1. Then solder the two conductors to pin 2 and 3. It doesn't matter whether you solder the clear cable or blue cable to pin 2 or 3, just make sure you are consistent on both ends.

Once you are done, it would make sense to wrap the exposed parts with a bit of plumbers tape. Other good practices would be to clean all parts, including the stripped wire with a bit of isopropyl or denatured alcohol, before soldering.

The 2534 may just surprise you. To my ears, it sounds as good as  many other expensive balanced cables that shall remain nameless.

Thanks for sharing and great stuff!

I would like to DIY my own balanced interconnect too. May I know where can I get the Mogami Neglex 2534 cable in Singapore?

Thank you very much.
