The Beomaster 4400 has an over-load circuit and I am wondering does it protect against a speaker hard-short?
I have had an “issue” with my second pair of speakers in that they are wired at the connection. Needless to say I am VERY careful about connecting these wires, but over time, say 6 months it seems a single strand of copper wire manages to touch the other terminal.
This “situation” was corrected permanently today by soldering the wires at the connection.
However, I am wondering if the horrendous sounds and resulting sparks arching between the posts might have damaged the Beomaster 4400.
All appears normal as both speakers and amplifier “appear” unaffected.
So simple question, does the over-load circuit protect the 4400 against this sort of problem?

The simple answer is no.Basically, the protection circuit protects your speakers if a failure occurs in the Beomaster - not the other way around.

I see. Then I must be grateful that it appears that no real damage was done to either amplifier or speaker.
This explains why the over-load lamp didn't even flicker.
Going forward, this "problem" can not repeat.
Thank you Martin for your much appreciated expertize.
