Axiom Home Page Forums General Discussion Technical Questions Receiver shutting down

Finally got some time today to begin the install: 60s, 150, 350 and two qs8's. Running from a Harman Kardon avr 325. Its 7x50.

Didn't get to install the 8's, left my 8 ohm Infinitys up there for now.

Problem is that I don't get nearly the volume I had with the little speakers, and when I turn it up, the receiver shuts off. Its the same with every source. I thought the 325 would be sufficient to run this setup, which was confirmed on this board, by Axiom and by Harman Kardon.

Why would the protect mode kick in? The polarities have been checked and double checked. Speaker size set to large. Brent said there shouldn't be a problem; must be something with the receiver. All amps and features were working fine before this install.

Good thing I have some Emotiva stuff arriving! Yahoo!

Still, I'd like to know what's up, if anyone has ideas. I don't like that something isn't right (and prevents me from LOUD), even for a few days.

Could you have a stray wire strand shorting between two contacts on the back of either a speaker or the receiver?

I checked several times; wired bare and with banana plugs, same issues. I don't usually leave wires hanging. I'll keep looking, though. I can't think of anything besides a short, either.

Does the HK have an ohm switch on the back? Maybe it's on something other than 8 ohms. Otherwise you might be limiting the available power causing it to shut down.

There's no switch on my 525.

No switch. Its all running from one outlet with plug in expansion (6 outlets, 4 used) and a decent strip (4 of 6 used); could it be insufficient current? No breaker is blowing; other components remain unaffected.

Is the HK brand new, or have you had it running with other speakers before?

I've had it for three years, no problems. It was running some small Infinity's and some cheap KLH's for my wife in the kitchen. It could be loud but never clean. The Axioms, even though something isn't right, are beyond comparison, but I can't get any significant volume.

Hmm, I don't know what to tell you, Chaitanya. Unless you are absolutely blasting it in a large cavernous room, you shouldn't be running into problems.

I hope the Emotiva stuff shows up soon.

Does it seem abnormally hot? Is the fan running? I run M80s on my 525, and I've never noticed the fan running. I do however tend to run at fairly low volume.
