Powerlink question

As discussed in another thread I am currently trying out a pair of Beolab 5s in my house and have moved my Beolab 9s to the rear. My house has Panamax in wall power link connectors with the power link in the walls. When I connected my 9s to the in wall power link there was a buzzing, due to to the older power link.

Solution was dealer shipped me some new power link cables to run to the 9s as rears temporarily.

Problem was the two power link cables were to short. I had a power link cable connector so I joined the two together and ran it to one of the 9s. It worked perfectly.

I then took an older power link cable and daisy chained the second 9 to the first 9. It also worked, problem solved, at least for trying out this speaker configuration.

If I end up using 9s as rears, I would prefer to not have to redo the in wall wiring so I had an idea. I can get a power link cable to one rear speaker totally hidden. So then I thought as daisy chaining to second speaker with old power link cable, I could use the in wall wiring to also daisy chain to the second speaker. When I tried that, both speakers buzzed.

I am confused why I can daisy chain with an old cable and it works, but not with the in wall old cable?

Perhaps the in-wall cable runs close to an AC power line (mains as they say around here) which is causing the interference.

If your left and right rear in the wall are NOT daisychained this solution will work.

The PL-cable (PL-mk1) to the right rear has a spare wire. That is the left signal which is the brown wire. The PL-cable to the left rear, same story. Here the right signal is not used, which is the green wire. 

The spare wire goes to the pin where the blue wire (PL-mk3) normally goes. Off course this has to be done on both ends.

But this only works if the in-wall wiring is not daisy-chained. If it is, forget what I said.

I hope this makes sense.. 

 

I am not sure I understand. Could you clarify for me what you mean about the in wall being daisy chained?

Here is what works: new power link from BV7 to one rear Beolab 9. Old power link from first Beolab 9 to second Beolab 9.

What does not work: new power link from BV 7 to one Rear Beolab 9. Old power link from first Beolab 9, (same as solution that works up to this point) but instead of running directly to second Beolab 9, connect to power link in wall. Then, second speaker is connected to the other in wall power link.

When house was built, the in wall power links were installed. There are three. The in wall power link runs from first wall plug to the second and then to the third. When I tried connecting the the 9s the first plug had nothing plugged into it. First plug is behind TV and was designed for one power link from TV to it and then the rear speakers would be connected to the other two. When I connected the 9s nothing was plugged into the first.

Thanks!

 

Now I am not sure I understand.. 

Anyways, in your old situation, if there is only one powerlink connected at the rear-outs at your bv7, the rear must be daisy-chained in the wall. If this is the case, you definatly need to re-wire.

If there are two powerlinks connected at the rear-outs at your bv7, I will try to give some more details.

 

Yes, there are two rear power link outlets in wall. One for left. One for right.

No, I meant how many powerlink-plugs are connected in your bv7, and then in particular the rears. One or two?

One in BV7, 2 in rear.
