In the BL14 satelites there are terminals (red/black) for the speaker cables.

Normally red is right and black is left!

But how do we know where to connect the correct wire in the sub?

The terminals there have no colour/right-left indicated (only to which speaker the cable belongs).

Any hints on how to connect them, please?

There is no left and right for a single (passive) satellite speaker. Red is plus, black is minus. Terminals on the sub can only connect one way. There is no way you can reverse it accidentally. That's why it's not color-coded.

Sorry, I did not get that Confused

Every speakers cable has two wires.

The red terminal usually is for the 'plus' and the black for the 'minus'.

No problem in identifying that on the satelites terminal. 

But the terminals (for the two wires for each speaker) can not be identified since they aren't marked (red/black or plus/minus).

If you accidentially connect them reverse the speakers would be out of phase.

The Beolab 14 Sub use RJ45 plugg to connect the satellite speaker !

 

POWER LINK (x3)

Pin 1 Not used

Pin 2 PL_Data

Pin 3 Signal GND

Pin 4 Speaker ON (on=> 2.5V / off=<0.5V via source)

Pin 5 Not used (PL power up)

Pin 6 Audio Right in

Pin 7 Signal GND

Pin 8 Audio Left in

???

BL14 sub got five two-wire-sockets for the BL14 satellites. The sockets are for L/R front, L /R rear and center. They are passive speakers and connected with two-wire loudspeaker cables. There are three Powerlink inputs for the six inbuilt amplifiers.

Sorry, I mixed up the input and output connections !

Please re-read my op!

This is not about the PL connection - there is no problem there.

But about how to connect the speakers wires (for the satelites) to the terminal on the sub.

At the satelites end the connections are marked (red/black).

But the terminals (for each speaker) aren't - there are two 'holes'/connections for the two wires (for each speaker).

How to know which of these correspond with the red/black connections, was the question.

I don't suppose that it doesn't matter which one you choose (per accident), since you then might create an 'out of phase connection'.

The only 'work'a'round' I see, is to be carefull and consequently choose the same (either the left or the right one) for each wire of the satelite cable (red or black connected). You could even mark them yourself with a red mark, if you please.

But why! aren't they already marked/colour coded?

That's my point. You can't accidentally reverse it. Same as you can't reverse a rj45- or vga-connector for example.

Sorry - I don't want to be too nerdy, but if you have two holes to put something into, you might accidently choose the 'wrong one' Embarrassed by chance of 50%.

If your explanation was right, there would be no need for colour coding the terminals on the satelites.

 

Edit! "Same as you can't reverse a rj45- or vga-connector for example"

Do the original speakers cables come with a plug at one end???

I'm asking this question on behalf of someone on the danish Peter Pan forum - and don't have the set/the cables at home.

In that case it would be quite easy Smile

But how would you do it if you preferred to use other/better/thicker cables?

Connection on the subwoofer is straight forward as the supplied cables have plugs on them which can only connect one way.  However these same plugs  do not reveal which is plus or which is minus. Neither does the cable. This is what is causing the problem: which part of the cable is to be inserted to plus (red) or minus (black) terminal on each satellite? The cable obviously contains two wires for each satellite and it is easy to tell them apart but this does not help when the connection on the subwoofer does not reveal which is plus and which is minus. 

 

Is there anyone who have experience with these and can confrm which is minus and plus (there is a core and a shield to each cable).

 

thanks BeoMedia

A picture of it would help.

If I got bored discussing the issue with a bunch of non-connected cables in my hands, here's what I would do:

  1. Connect them all the same way
  2. If the end result sounds like crap, reverse them all
  3. (Post the correct orientation here for future reference)

This time, it obviously matters which way the satellites are connected (even if they are all connected the same way), because the internal subwoofer has a certain fixed phasing.

I have check in the service manual for beolab 14, and can not find the solution.

Core is +/red, shield is -/black.

As you can see, there are no ’holes’. Like I said in my very first post, there is no way you can reverse it accidentally. The BL14 comes with speaker cables with plug. If you are a 'cable believer' and want better/thicker cable, you can't. Hope things are clear now!

Thanks but how do you know for a fact that core is red / positive and shield black / negative?

I know the cables have fixed plugs in the other end (connecting the sub) but little help when designed without plugs in the other end and consumer is left to guess.

@DoubleU

I'll have to apologize Crying

I did not know from the first informations of the BL14 owner, that the cables have a plug at one end!

 

Now BeoMedia has posted here too and can speak for himself, but - as you see - things aren't quite solved for him.

N.B. The picture, I asked for, was one of the cables - I still can't belive that the cables aren't marked in some way.

No problem! Yes - thumbs up

And it may not be written in the manual that the core is red, and shield is black. But with some technical background, you know this is a fact. If it would damage the system, by reversing the cables, it would certainly be written in the manual. (I guess if you do so, and phase the sub 180' with the potmeter, you have the exact same result)

And otherwise follow Mika's advice. Just start connecting, be consequent in the wiring, and let your ears be the judge. You'll end up fine!

UPDATE!

BeoMedia has just written, that he now has got a missing user manual, that solves the question how/where to connect the two wires of the speakers cable.
