If they used an 8-pin powerlink, then it is either a Mark-II or Mark-III, either of which will work with your Beolab 3.

So.....Don't worry!

Hi, there is a small chance that they may have used mk.1 cables (these are very thin, without the triangle symbol on the plugs).  If this has happened, the only problem you are likely to have is that the Beolab 3 speakers may give a humming or buzzing noise that can be heard over the music.

If you do experience these problems, I would suggest asking the store to change the cables for you.  Otherwise, there is no need to worry, as the quality of the wiring in the cables is the same for each version of Powerlink cables.

If you do decide to change the cables at any point, you may wish to bear in mind that there are other brands of cables available for your Beolab 3 speakers with very high quality wiring and gold connectors, which you can either purchase yourself, or through your B&O store.

Kind regards,

Steve.

Three years of use indicate that they installed an appropriate cable -  the speakers
would have delivered loud hum immediately when connected to the wrong version!

Don't worry, a fully mounted Mk 2 cable (all 8 pins connected, NO TRIANGLE on the plug,
cable diameter approx 3.5mm) will work for ALL BeoLabs.

Pro-Installers preferably use the FULLY MOUNTED version because:

- this cables give the customer the freedom to use ANY B&O speaker later on
- the cable is less sensitive (better schielded) to interfereces coming of external units
- it's more robust when you pull it through cable conduits  

The former "thin" PowerLink-cable (3 wires + shield, cable diameter approx 2.5mm)
has been replaced by the Mk3 version (4 wires + shield, cable diameter approx 2.6mm)
needed for all speakers with ICE-Power amplifiers like the Beolab 2,3,4, 4000Mk2, ....
(exept the BeoLab5s which will always need a fully mounted cable)  

The triangle on the plug makes the "old" and the "new" version of the "thin" cable distinguishable.
