B&K 200.5 S2 Power Amp problem - Please help

Hi guys,

I need your help and advice please.

I purchased this power amp on Ebay a few months ago. I just realized the amp is having a problem after I heard my friend's B&K 7250 version II (old model). My power amp, all 5 channels, has had low output. Is that possible that my power amp blows the fuses? If yes, do you know where can I buy them? Since B&K company was taken over by ATI company recently, it's hard to contact them for advice.

I'm really appreciated for all your help & advice.

Thanks!

First, all your fuses would appear to be 'good'. You ARE getting output from all 5 channels, right?

Look at the back panel. There will be a balanced / unbalanced switch near each set of inputs. IF you are using RCA connections, make sure it is set to 'unbalanced'.
Turn the level way down...or the system OFF before adjusting this.
I'll bet the last owner used balanced connections and it is so adjusted.

Also, how sensitive are your speakers? I can't believe that is the problem, but it never hurts to ask. This amp should even drive my low-sensitivity panels OK.

I read the instructions:: no level controls inside the amp.
