Making my own powerlink mk2

[Lluís Campaner]

Helloo,

So a few months ago I bought a pair of Penta MK2 with a beomaster 6500 as I was so happy with my first b&o product a beolab 2500, but I’ve been having some trouble and I come to ask if you could help me.

 

I bought some really cheap 8 pin cables and everything works but everytime I change the volume or do anything with the remote I get some kind of interference, as far as I understand it is cause the cables are not shielded.

And now comes the question, as I don’t have a big budget and because I would like to make my own custom length cables is cat6 stp a good cable for this use case? Or should I go for other kind of cable?

I would be really grateful if you could help me as I have not been able to find info on this topic.

 

(On the extra note the transformer on my beomaster is really loud, is this common? Just tightening or adding some cushions could fix it?)

I think it depends on how the individual cables are shielded.

If you can fin the Beolink Handbook (available for paying members on Beoworld In the Biotech section) you can see the cable drawings with pinouts. For the RJ45 Powerlink cables the wire collars are the same as n a network cable, so I will assume it can be used. I did use I Believe CAT6A network cables to make some short RJ45 to 8 Pin DIN adapters at some point, and they work fine. But might be different for longer cable runs.

Danish Soundparts (a Beoworld Sponsor) do sell some new support rubber bushings that may help alleviate the problem:  https://www.dksoundparts.com/product/transformer-bushings-beomaster-3500-4500-5000-5500-6000-6500-7000-etc/

I replaced the bushings on my BC9500; it still hums but to be honest I cannot tell if the humming is reduced!  The old bushings were very brittle, however, so new soft rubber should theoretically improve the damping.  You could also look at re-positioning the Beomaster away from any shelving that may resonate and amplify the hum.
