Hi! 

Can I use a 7 or 5 DIN powerlink in order to make a RCA-powerlink cable to connect beolab 8000/6000 to non B&O receiver?

Thanks!

Liviu

I would use data link cables cat. 6 or 7, if you tell us where you are situated, someone may have a link to a seller

I am in Romania. I am asking about the type of cable : shielded or not, how thick cables should be, etc...Something like this will be ok? I am asking for a picture or a link only to see how it should look like. I will find it after, but don't know what should I look for.

Do the cable have any influence in sound quality? ( like for passive loudspeakers) Or is it more tolerant.

What specifications should I look for?

Thanks!

I found this instead of the zener diode + 680 ohms resist  for trigger part of the cable:

Is it ok?

If I will use a telephone charger 220 V - 5V that means the loudspeaker will stay on all the time or it will be "green"only when audio signal is received?

Should the ground from trigger and negative from RCA  linked together?

Hi,

if you use a telephone charger (5V) the speakers will always be switched on. The 5V are a signal from the B&O Audio / Video Output to the speakes to switch on (=5V) or to switch off (=0V).

The cable you showed is not useful ! Atleast the two wires carrying the audio signal should be shielded. The 5V trigger line doesn't need to be shielded, but it's probably easier to get a cable where all wires are shielded separately than the special B&O cable itself.

1. But a car telephone charger modified in order to use a minijack to the 12 V output of the receiver will work?

2. Will a datalink cat 6 be good enough ? ( sound quality)

3. Should the grounds from trigger and RCA conect together to pin 2 and pin 7 left unconected?

It seems that last questions were without answer :)

I have another one: if I cut a 5m mk3 powerlink cable and use the cut end to conect to RCA and mini jack will it work? It has both the 5 and 3 pin wired, so it will be a problem if I will let this wire unconected in the left and right cable?

And what should I conect to pin 2 and 7 ( question left unanswered) : on the mk3 schema it says : pin 2 = ground ( shield)

pin 7 = mass data line ( shield 2).

Thank you very much! I hope tommorow I will make it and post the results.

P.S. I also tried today a B&O original RCA - powerlink cable which didn't work with beolab 8000. Switch = powerlink---> red..........switch = line --> HUM......switch again to powerlink = green/music, but turn red /off after 1-2 min and never again green.

It can be started again same way ( powerlink---> line--->powerlink) but for same result ( 1-2 min of activity).

For the 3rd time (1 time Mika, 2 times me), pin 7 is not used in BL 8000, and trigger must be pin 4 and pin 2.

Connecting powerlink without the trigger will not work, and switching to line neither, if using line in it has to be RCA to RCA, if using powerlink with trigger it has to be L or R,

I may be missing something, but why not make this easy on yourself and forget about the Powerlink connectors? Just switch the speakers in LINE mode and use regular RCA-RCA cables from the receiver to speaker.

I think you're making this way too hard on yourself.  If you are, intact, talking about BeoLab 6000/8000's.  Both of those speakers have RCA inputs on them.  No conversion cable is needed.  Set the input switch to "Line" and they will work just fine, including power on/off.

Tournedos and RussR,

 

thank you...I am using an RCA-RCA cable right now but there are 2 problems:

1.movies - when there is a scene with dialogue the front 8000's will turn off and it will not be very annoying but

2. one loudspeaker when turning off ( during a movie) starts a sort of clipping...on/off/on/off.... very quick (15-20 times/second) ....solved by muting the sound....waiting the loudspeaker to turn off ( usually in 3 second) then turning on the sound again.

That's the reason I am trying to use powerlink input.

Thanks!

So, why not getting two long 8 PIN Powerlink cables ?

Ct them in the middle and solder rca, XLR, whatever you need to the open cable end - and you won`t have to think about the Powerlink end.

Use the cabling (5 PIN) as shown in Peter Pans drawing and connect PIN2 and PIN7. So, maybe one day, if you want to replace your BL8000/6000

with ICE Power Beolabs (BL3, BL12...)  just cut the connection between PIN 2 and 7.

I`m sure, Peter Pans circuit will work - as far as I know - he uses exactly this circuit in his own setup....

You will need a non Beo receiver with preamp outputs with regulated line level, so of course the cables must be shielded - they are no speaker cables.

BTW - I strongly recommend to let the work done by a trained technician - sorry, but maybe it`s better for your Beolabs...

I finally made it. I cut the 5 m powerlink mk3 cable and solded an RCA + trigger.

It works as I wished but it has a little "noise". Don't know if it's new or it is there even with the RCA -RCA cable.

Are your beolabs perfectly quiet when they are on but no music????

Thanks for feed-back and for all your help.

Try this then:  Use the RCA-RCA cable, with the input set to 'Line' but keep the DIN connected for the trigger only.
