Connecting a B&W PV1 subwoofer to a PowerLink socket

24 replies

Dear all,

Sorry, newbie question again 😳

The B&W PV1 subwoofer has a Line input, which is supposed to be connected to a dedicated line-level subwoofer output.

So... which sort of cable should I use to connect my B&O audio master's second PowerLink socket (the first one is connected to a pair of BL8000s) to the PV1's Line input, taking into consideration that the resulting Line signal should mix both left and right signals to feed the PV1 with?

Thanks a lot to the technical guys here who know the answer.

Kind regards, Jean-Sebastien

ItΒ΄s in Danish, but maybe the picture will help you.

Thank you, Daniel.

I am not sure I understand the picture: it seems there are three connections going to the sub, but the PV1 has only one?

Cheers, Jean-Sebastien

That picture only shows a powerlink T-adapter which turns a single powerlink connection into two (for example, connecting a pair of BeoLab 8000s to a B&O system which only has a single powerlink output).

It's not the easiest thing in the world to do. You need to wire up a cable which adapts from powerlink to two phono (RCA) connections.

I'd recommend you take the wiring diagram seen below to an electrician or audio service store (most hifi stores or B&O dealerships should have some facility to do this, or at least point you in the right direction).

Wiring Diagram

You an click the image to go directly to it, where you should be able to go File > Print.

Just let the people doing the work that you want a cable with that plug on one end and two phono (RCA) plugs on the other end to connect into a subwoofer.

B&O do produce some 'PowerLink to Line' adapters which are almost correct, but actually will only carry the left hand signal (I believe, although it may only be the right) so the subwoofer will only end up reproducing one of the channels...

Hope this helps! It's not the easiest thing in the world to do if you don't have any experience with wiring (which I'm assuming you don't).

Easiest way is to connect a 5 PIN DIN plug to 4 Phono plugs into the powerlink socket and connect the sub to the two phono plugs with a signal - I learnt this a while ago when I bought a Beolink Active kit and connected an amp and speakers to teh powerlink socket as an interim measure until I could afford some Active Speakers.

Surely all you need is the pin 3 and 5 output going to the positive and the pin 2 output going to the negative. Fairly ropey collections of connections and interesting there is no output thus your other speakers will still be dealing with full frequencies.

Looking at the wiring diagrams next to each other more closely, it looks as though you could just use a 5-pin DIN audio > phono (RCA) cable, and connect the 'Audio IN' connection to the Subwoofer instead of the 'Audio OUT' connection.

Thank you for your replies. You all talk about conversion from powerlink to two phono (RCA) connections BUT the PV1 has only one single Line input, so I am not any further with two RCAs...

How can I get left + right from PowerLink into one single Line connector???

Cheers, Jean-Sebastien

As I said, connect both output wires to the positive and the pin 2 output (common ground) to the negative. One channel combined.

js,

 I have been looking at this very point and whilst I don't know the answer I have a suggestion which Peter or Alex could shoot down. If you don't want to have the hassle of soldering etc then I would suggest a 5pin to 4 Phono leads (as suggested by Alex) and a two female to one male phono connector available from Maplin.

 If I am right  this should work but don't do it until someone more technical that I authenticates it. Over to you Peter/Alex.
