i m newbie about hifi.
i ve purchased an onkyo cr n755 and a pair of dali zensor 1

i dont use banana plugs. and i didnt notice open ends of + and - cables touch each other.


onkyo shut down itself after 10 seconds music play automatically.

i didnt understand and run it again. and it shut down again.

is it a protection of onkyo?

Yes. You have a short. That's damaging to equipment. The shutdown is for self preservation.

You need to fix that short. It is a fire hazard and a danger to your electronics.

No way to be entirely certain: but if it's working then it's working smile.gif

And he's very lucky.

(I don't remember ever seeing an AVR or amplifier owner's manual that wasn't very explicit about not shorting the speaker wires.)

Get some banana plugs and you'll have less chance of shorting your wires.

I had Thiel 2.3's which had the speaker connections on the bottom of the speaker. I brushed up against on of them the cable came loose and they touched. It fried one of my amps and it cost about $350 to fix.eek.gif

but i think new and high end brand amps have protecitons against this problem.
pioneer and onkyo for example

Protection circuits are standard on pretty much all amplifiers, but repeated shorts will weaken electronic components. You're lucky your AVR still works, but a little common sense goes a long way. Also reading the manual.

I don't know why you are advertising this lack of common sense.

Fix the short for goodness sake!

There is a good chance that the receiver is not damaged.
