DIY Multicore Audio cables DB-25/JACK and XLR advice

Postby Primary perception » Fri May 14, 2021 10:13 pm

Hi guys,

we are updating our studio, decided to get into the patchbay world in order to have all the gear connected.

We need a bunch of Multicore cables DB-25-JACK and XLR, we have asked for prices and its too much for our budget if we want quality cables and connectors. So we are gonna try a DIY cables.

We have no experience with soldering and we'd like to test us first with some cheap materials to get confident and then jump to the good ones and do the job.

What are your thoughts about, its a crazy idea?, how long could take to achieve the proper skill?.

Thanks very much in advance
Best

Given the price of the CPC DB-25 to jack cables I wouldn't bother with DIY. They're perfectly good for a fixed installation. Soldering DB-25 cables isn't something to be taken on by the inexperienced - you need to know how to do neat and reliable joints in a small space if you want them to work.

The CPC cables can be found at

Whilst I agree with James, making multipin cables is a tricky skill to master, I am always loathe to put anyone off from audio DIY!

However, some idea of what is needed to do the job properly might put OP off?

A good quality, temperature soldering station is the first step. Budget £50 up for that.

Cable, for 'static' work use ~3mm OD foil screen two core cable, easy to strip and the single drain wire avoids shorts.

A good quality automatic cable stripper speeds things up no end.

Plenty of around 2mm bore silicone sleeving down EVERY wire and over the D pins.

Small, swivel bench vice and a test meter and you need to be very methodical in testing and labeling the cables.

60/40 Lead solder is easier for the newb to use but circumstances might dictate the use of Pb free solder. In any case, have air blowing fume away and do not eat, drink or smoke when soldering.

Dave.

Not sure if they do - but the same thing is available from the German Farnell website
