Hello @nitro2

Couple of questions: what is the source? Is it a Beomaster, a tv or other line-level product?
If a Beomaster is used, what volume is shown on the Pentas?
What type of music? Does it happen all the time when any source reaches the same volume?

Location: Kent, UK
Favourite Product: Beosystem 6500

Type of music does not matter , the 4 of them are connected to a beomaster 7000 , volume on the set around 40 when the “soft clipping “starts on 1 of the 4 penta’s ( always on the same unit )

And this problem excists whatever source is played , always around 40 ( ish )

Could suggest that the amp runs not symetrical.
Any DC on the speaker output?
