Re: Baehr Whine
Just a quick update on my Baehr whine problem.
I've finally received and installed the (rather pricey - $114) noise supression cable, part number AEF-02-02, for my Baehr intercom system.
Since availabiltiy of this cable is quite limited here in the US, I ended up buying three of them (one for me, two for a couple of other forum members) from Baehr in Germany. I'm VERY disappointed to report that the noise supression cable hasn't helped a bit. The whine/clicking is still there. Hence, I'm quite interested in the recent ground loop isolator threads. As soon as I can fiugure out what it is, and where to install, I'll likely be trying that.
At this point, I've tried;
1) Daza's fix by running a separate ground wire to the intercomm.
2) Moving the intercaom unit itself
3) re-routing cables away
4) the Baehr noise supression cable
...none of which have helped. I must say that considering how much money I have invested in this intercom system (approx $1300), I'm very disappointed to have to listen to this whine/clicking. The only thing that has helped so far, is to wear ear plugs, which cuts down on the high frequency sounds, and really helps to drown out the whine sound.
I wish I could think of clever things to say in my signature.
