Hi

I have just replaced my Connect (v1) with at Port…

I have a setup with port in one end and 2 B&O active speaker in the other using the Line-entence.

I have a 10m cabel in between (and this is the issue)

When the POrt is not active, the speakers make a constant buzz and never power down.

There are a constant noice from the speaker…

If I replace the 10m cabel, with a 0,5m cabel  → no problems…

 

My Clever friends talks about, the 10 cabal acts as an antenna, when not in use and this

is the reason for the constant buzz…

When I used the Old Connect, it was not a problem.

What Can I do??

Your clever friend may be partially correct. Does the 10m cable go near any power wiring, power supplies, or large appliances? 

Is PORT using the same outlet as the B&O speakers?

If possible, experiment with flipping power cord orientations. You may find a combination that will minimize or eliminate the noise.

Is anything connected to PORT’s Line-In? If so, temporarily disconnect this source.

Try a better quality cable? 

Alternatively try grounding the Port (and possibly the B&Os). As an experiment touch a wire between one of the Port’s RCA sheaths and something you know is grounded, such as an earth pin or a bare water pipe.
