Do you have something/a device at home, that you could connect with a phono L/R cable at both ends?

If yes, please try that - and then swap the left to right input/BS4 etc to see what happens.

Have you had a play around with the L/R 'balance' settings on your iPhone?  For some reason they are under the settings, 'General' and then 'Accessibility' menu - scroll down towards the bottom and you'll see the slider.

Hi MM,

Thanks for the reply and suggestion. I have plugged a blue ray player with individual L/R phono cables at both ends and the sound is the same (if I swap the output from the BR player the sound remains the same on the right speaker, a static sounding treble heavy and amplified screeching! You can make out the audio that is trying to be played however it's not pretty!

I have the Beosound 4 connected to a pair of Beolab 4000's and if I set the switch on both of these to L both speakers are good, if I set either to R the distortion happens in whichever is designated as R. 

So setting both speakers as L is a work around however I fear I will be missing quite a bit of detail in stereo tracks.

Does that all make sense?!

Thanks again

Paul

Hi Guy,

Great suggestion, I wasn't aware of the ballance setting in the iphone menu. I gave it a go, if I pulled the balance almost all the way across to R, the volume reduced in the right speaker and the clarity improved a little (if output volume was kept on phone at about 50%. Only trouble being the L speaker is way louder so in practice can hardly hear the right!

Thanks again for the suggestion though, it is an improvement of sorts.

Hmmmm - I could not believe this. 

If everything else plays fine, it really seems that the input port is faulty - probably a loose connection.

Something that you can only determine by opening the unit, I fear.

At least I have no other suggestion.

By the way - welcome to Beoworld.
