HELP!!!! I keep tripping my receiver off - Blu-ray Forum

shark420 · 07-17-2009, 07:27 PM

OK I am not sure what I can do in the settings to help, if anything, but when a loud sound effect goes through the speakers (explosions and such) my receiver is tripping off and it shuts everything down. The receiver has all of the speakers set to large. Equipment is listed below, really starting to get frustrated that movies are starting to get shut down when a loud bang or explosion goes through the speakers. BTW The 2 subs are set at the middle position on the sub itself. In the receivers set up all the speakers are set to a +2.5db level except the subs which are set to a +1.0db level.

ANY advice is appriciated and thanks
Jeff

Sounds like your receiver in going into some kind of protection mode.

However, first thing I recommend with those speakers is to change them all to small, especially if you have 2 subs. Set all the crossovers at 80hz for your speakers (although your 70's could handle being set at 60-70hz) and at either 80hz or 120 hz for your sub in the receivers set-up. On the subs, I would keep the volume at 1/2, but make sure you open the phase completely (the low pass filter) so your subs will accept the complete LFE signal being sent from your receiver. Also, check your db levels (perhaps get an SPL meter) as you may be running your speakers pretty hot when set at large along with those db levels, but this is a guess on my part.

What kind of volume level on the display are you running your set-up when watching a blu too?

Try that for a start, and maybe you will get better results from your receiver.....

Sounds like a classic case of " I need a voltage regulator/power conditioner ". Check your local electronic shops for a cheap one.

you dont have your subs plugged into your receiver by any chance do you? Its definately going into protection mode..

Shark420, you're asking/expecting too much from your 'little' Sony 920. The reason why you're receiver keeps turing off is because it's going into protection mode. This is a good thing because it keeps your amps from frying and your speakers from getting damaged from the possible clipped signal. Basically, you're pushing your receiver to hard. What volume do you listen to your movies at?

I would suggest that you set all your speakers to small with a LPF of 80hz-120hz. This will take a great demand of your receiver as lower frequency require more power to produce the same db level output as say higher frequencies. I see you have polks as I do. The Monitor 70s are power hungry speakers to begin with. So like I said, set your speakers to small and send the LFE to the subs. This will open up the soundfield, not put as much strain on the 920, and give you more dynamic head room for your 'loud explosions'. This in it's own respect should eliminate your issue. If you still have it, I'd suggest looking into an external amp if your Sony has pre-outs.

Actually, I had the same problem with the same receiver. It was from the wires touching the receiver. I reseated all of my speaker wires, never happened again. Not from "asking/expecting too much from your 'little' Sony 920."

Jason, if this was the case, what bearing would the explosions and low frequencies have on it shutting off. It seems to only happen during these moments in a movie?

Not sure, but mine only happened at louder volumes as well.

That is uncanny. Maybe the explosions rattle everything so much that this would be the only time they would "touch?"

CasualKiller · 07-17-2009, 08:00 PM

I had this problem with my old Sony DG910 and see it often on CAM forums with older NAD gear, pretty sure he needs some power management.

And if I'm wrong look at the bright side, most stores have a 15 day return policy...

Edit> Of course before running out to the store you can disconnect all speakers and your sub and crank the same scenes that are causing the fault with no speakers running. If it trips your protection mode again your amp is fried...

shark420 · 07-17-2009, 08:31 PM

thanks everyone for your advice/suggestions. Actually the reciever is about 1 year old and all the speakers are new, thanks uncle sam. If it matters I think the speaker wires are probably touching the metal shell of the reciever so that is probably a bad thing, no banana plugs or anything like that just sliced off the plastic wire coatind then ran them in the holes for the speakers. I was sure a more powerful reciever would have solved the problem but I am at 110 watts a channel I beilive and shouldn't that be enough + do not want to spend another 500+ for a new reciever. I know there is a setup that plugs the subs directly into the fronts (monitor 70's) anybody running their subs through their fronts felloing thats better than directly into the receiver?

THANKS AGAIN EVERYONE

Forgot to add, I was told by more than one person to try the "power magagement route" but honestly I have ZERO clue on that one so any advice their would be nice also.

I would get one, but that's not contributing to your receivers protection mode kicking in. I agree with the others to check for stray wires, and if that checks ok, definitely set your speakers to small. That receiver may be rated 110w but I would bet it's putting out 45-50w with all channels driven.

Stray wires meaning bare speaker wire touching the receiver's metal?

Yes. Also check at speaker.

Stray wire meaning ANY bare wire touching ANYTHING else.
i.e. receiver metal, another speaker wire @ the receiver or at the speaker post.

Steve · 07-17-2009, 09:34 PM

Stray wires touching anything is BAD. This is another reason banana plugs are so convenient. I will also reiterate what others have said about setting your speakers to small. This will take a good deal of strain off the receiver's amp, which will allow it to run more smoothly. Also, as already noted, your receiver most likely isn't pushing anywhere close to 110 watts per channel. It probably does with only 2 channels driven, but with 5 channels driven it's probably closer to 60-70, and with 7 channels driven it's even less.

There's no need to change anything, he needs a power conditioner.
