Hi can you help me?

i have the marantz sr7012 and got Harman kardon Signature 2.1 from a friend. I really like the sound but got som problems and wondering if you can help.

first of all, do i have to change Some settings in marantz? I have the H/K for front and center speaker.

the problem i have is that when i start everything up (have a trigger Cable) sometimes the center just have a test tone noice and the fronts sounds really low and sometimes the center is whitout sound and fronts sounds low And sometimes it works great. Why is this?

Speakers front sonus Faber venere 1.5 6ohm
Center sonus Faber chameleon 4ohm

And when i turn all of and on it always popps in the speakers.

All This doesnt happen if i only use marantzs
 
If you are confident that all of the wiring is correct, no stray speaker wires anywhere, it is quite possible that the power amp is faulty.

Try testing each channel on the power amp one at a time, have you got a spare speaker and something with a volume control that you could use as a pre-amp for testing?
