Re: Connecting a B&W PV1 subwoofer to a PowerLink socket

Behringer do a professional class crossover called the CX3400, which works very well. Can't say I've come across any 'consumer' crossovers, the CX3400 would do the job, but you'd need the correct cables made up (it uses XLR connections).

The older ones don't sound too good (quite 'brittle') but the latest ones (which must have different components) sound different, for the better!

I really don't see why that should not work.

I am sure that you can get an active filter - but I have no idea of the cost. If you do a google search, it lists a number of options.

Peter :
Surely all you need is the pin 3 and 5 output going to the positive and the pin 2 output going to the negative.
Thus, Peter, do you mean that I just have to solder both left and right output wires together to combine both channels? Is it really as simple as that? No collateral issue?
Peter :
interesting there is no output thus your other speakers will still be dealing with full frequencies.
You are right, Peter, and this is the reason why I am still hesitating between BL2 (filters the lower frequencies, thus enables the BL8000 to sound better) and PV1 (is faster and more musical).
Now, when using the PV1, the ideal solution would be to have an active filter between the audio master and the BL8000 in order to filter the lower frequencies, like a BL2 would do. But does such stand-alone active filter exit? That would be VERY interesting to find out. Anyone?

Anyone, please?

Hi Peter...so is the BV2 a "dual voice coil" speaker?? or is it just a single with both channels represented?? thanks..

Pretty sure it is single coil but here is the block diagram showing you what it does.

Hi, in a video setup, you can buy a phono line-Powerlink adapter of the type that goes with BeoLab 3/9/4, it works both ways!

Connect the Powerlink plug to the back of your TV, and the phono plug to your subwoofer, you'll get both left & right channels on your sub, I do this with my B&W subwoofer that is connected to my BV3.

The Beolab 2 does take both and also applies a filter so that the lower frequencies are not passed to any attached speakers. A big advantage with some of the column speakers. If used in a home cinema set up, I would set the system up with just the LFE going to the PV1 and, yes, set up as one would with the BL2.

I was not aware that BnO's subwoofer took both channels. I really don't see the need for bass in stereo. Most bass tracks are laid down on both channels and mono. You can't hear the difference, except in very few songs where they may change channels...

can I also ask a newbie question here, in speaker type menu, when you connectPV1, do you still pick beolab 2 as the speaker connected??

Thank you all. I will try and report.

Frank Rizzo:
Why do you even want both signals going to the sub?? Just use the left or right...or buy 2 subs and drive both...
Some subs have dual (2) voice coils and will take both L and R...but just use a cheap $15 USD adapter off ebay from Powerlink to 2 RCA's and drive the sub. We did 2 subs and it was too much for anything but movies...even then we would switch off 1 sub at times...
good luck ...

Because otherwise the subwoofer is only reproducing the bass found on one of the channels, not on both as it should?

It *should* work, although as I said, rather than use the 'output' connections at the end of the DIN > RCA cable (which is what you would expect to use), you would have to use the 'input' connections.

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.
