    A few days ago I was testing out the Onkyo595 at Circuit City and it had some problem. I would turn the volume up to about 70 and the reciever would say "protect" and shut off.

    I turned it back on and it would do it again. THis was during a cd and the radio. I then changed a setting to STEREO and I was able to turn it up loud.

    Then when trying it out with a DVD it gave me sort of the same issue.

    The guy at the store said the reciever was broken.

    Anyone know what to make of this?

    I am thinking of getting this reciever mainly due to recommendations and I have yet to find a Denon 1802 to try out anywhere.

    Thanks in advance

    The sales slug as usual was WRONG.. The Receiver is not broken.

    My 787 does this also and all it amounts to is NOT enough

    balls in the amplifier section to power the speakers at

    high levels. Dynamic peaks in music can drop the ohm load

    on speakers as they play and at high volumes this just puts

    too much of a load on the amp and rather than keep playing

    and risk frying circuits it goes into protect mode.

    The awnser to cure the problem is to pick a pair of speakers

    that do not need as much juice or just buy seperate amps.

    I am going the latter route as I am NOT about to ditch my

    towers.

    My 787 puts out 100 watts per channel and even in stereo

    mode where it's gaurenteed to get all of those 100 watts it

    is simply not enough power to drive my towers which in reality

    should have no less than 100 watts going to the Mid/High

    section and at least 150 watts going to the Sub (low) section.

    What speakers was this Onkyo wired up to?

    Hey,

    The speakers the Onkyo was hooked up to were a pair of Polk Audios, not sure the model # but they were about $400 , tower speakers. They were also hooked up to a Velodyne sub and I think a Infinity center speaker?

    So you are saying basically the Onkyos don't put enough power? Hmm now you have me thinking twice about getting one.

    Now, when you say go for speakers that don't need that much power what do I look for when looking for speakers as I don't want to have to buy seperate amps.

    70? Jesus... 70 on my 595 is 6 over reference level (and I'm running Polk R10 mains and surrounds with a CS175i center, PSW350 sub). I'd be scared to crank it that high!

    One thing that could be causing this is if they have any of the speakers set to large. With them all set to small, you could probably turn it that high without a problem (since the bass management would be taking a lot of the load off of the receiver's amplifier section).

    Of course, being that it's Circuit City, I'm sure it's something they did... since they know about as much about home theater as my dentist does about anal polyps.

    Jeremy,

    That is exactly what I was thinking 70 is way too loud. If you want to push speakers that bad (& at 70 on the dial you are probably hurting most speakers) then get seperates as mentioned above or something like an Onkyo 989 or Denon 5800.

    Eric,

    70 in most rooms will be ear bleeding levels. How often are you going to play that loud? If you are concerned about it, then I would go with the Denon AVR-1802 and get a pair of amps for the mains. Then you should be fine.

    It could have been a bare strand of wire touching on one of the surround or center speaker wires that could have caused the protect mode as well. Sometimes shorts don't reveal themselves until you crank up the volume.

    I agree with Kevin; sounds like a short somewhere in the surrounds wiring; happened to me when we built our HT; the contractor hit one of the wires when he was putting up the finishing crown molding; also agree that 70 might be pushing the decibal level; my 797 is extremely loud and stable at 65.

    I guarentee it wasn't a short.. Well ok.. It was CC so I

    can't guarentee anything..

    But since it was a pair of Polk Towers which undoubtedly

    have a subwoofer in each cabinent and it's unlikely that the

    person who set it all up turned the mains to "small" the amp

    in the receiver just doesn't have the balls to push the subs.

    With my 787 this is where I run into problems.. I can't even

    get past 64 or so before the receiver goes into protection

    mode and this IS from the subs.. Set it to small and I can

    drive them to max volume without any clipping (and yes it is

    ear bleeding) but as soon as I put the bi wires back on for

    the dual 10" subs off the receiver goes.. The awnser? Don't

    buy large towers unless you plan on good seperate sources of

    amplification.

    I don't have any shorts anywhere in my system....
