Hey there,
I need help! Just got the HK 525 receiver and just hooked it up to bos A10 speakers. After 5-10 seconds it automatically turns off. There's nothing wrong with the power source...any ideas what it could be besides a defective product?

Thanks!

The speaker impedence may be causing the problem. What impedence are your speakers?

I'm afraid I don't know the impedence of the speakers...from the technical info provided by Bose, this was all I was able to figure out:

Connectivity: compatible with A/V receivers and amplifiers rated from 10 to 200 watts per channel, rated from 4 to 8 ohms

I know that the HK AVR-525 can handle this, so I was figured that the receiver was compatible.

Any suggestions?

thanks.

Aruna: check all your wiring. Just for fun, try disconnecting all your speakers. Turn on the reciever with no speakers attached, seee if it shuts off. If not, continue the process adding one speaker back at a time. During this, check all wiring and make sure you have no loose "strands" touching anything.

Other than that, you may be running into a real problem with the amplifier section going into protection.

generally when something shuts down it's from one
of 2 things.

overheatng.

or working to hard. mostly from low impedance speakers.

or just plain something shorting out.
speaker wires or something inside the reciever.

Thank you all for your suggestions. I unplugged all the speakers and still had the problem, so it looks like I'll be sending it back.

It's ironic that the first "nice" stereo equipment I buy, I have problems with! I should have stuck with the kenwood shelf system I have that cost less that $200 ;0)

thanks again

Aruna: don't fret. I went from the high end Kenwood KR-V990D to the H/K AVR-525. I haven't had any problems at all and I have run mine at exceedingly high volumes and run times (I have moderately inefficient towers that demand attention).

Sorry you got a bad apple, but there's one in every bunch.

Kegger: you gave 3 reasons, not two! :-)

I purchased a H/K AVR 430 refirb form ebay that had the same problem. I think it is an internal short. H/K honored the warranty no problem and even shipped me a new one (cool). No problems and sounds like a gem. Using energy veritas with it.
