Denon X3300W not playing nice with External Power Amps?

[olddog]

I was trying to set up my X3300W with a ex amp for 2 chanel stereo listening on a seperate set of speakers Zone 2. When hooked up the sound is distorted like a blown speaker (speakers fine)
So I hooked the ext amp up to the mains and same thing on another set of speakers. I have just had the Ext amp serviced and it works very clean on another system. All sound is clean using the internal amps on the Denon through all 7 chanels. Using the Zone 2 out and have front height set on the Denon. Checked all connections and changed out all I/C's. What am I missing???
Thanks for your time

Are you saying that you hooked the amp to the main preout to try it? What amp is it and when did you last check the operation of it?

 

[olddog]

Yes after I tried it on Zone 2 I hooked it up to the mains to check if there was any diff. Nope. It is a just re-furbed Carver M-1.0t MKII Opt2 that I checked out on a pre on my bench and is working nominally with no issues.
Thanks

Do you have a volt meter or a hand held scope? Maybe you can test the outputs and see what they are putting out
Where are you located at? Maybe someone close to can help with the test gear. If your near Orlando I can help

You may have a defective unit but what stands out to me is the front height setting you mention. Shouldn't be set for front height if you want to use it for the main L/R channels but I may not understand what you mean by set to front height....but if it sounds the same on the actual L/R preouts, I go back to thinking defective avr.

I am in Texas! I do have a meter and a O-Scope. I will check the output on Zone2 correct?
Thanks

Not to be insulting, but did you have both amp outputs connected to the same speakers at one time?

Check the Zone 2 output level setting- it may be at WOT and fixed- is it really loud when this happens?

Could be a defective AVR, especially if the amp works fine with another AVR or preamp.

No insult taken! No volume was auto set to low and I had to raise the volume up. Low, very low can'
t tell the distortion. Raise it to listen level and there it is.

What number was showing on the display, for the volume level?

You said it would do the same when you connected the ext. amp to the "main", presumably you meant main zone preouts such as FR, FL, in that case if has nothing to do with which zones.

What is "auto set", you meant the mute limit? What was the volume displayed when you could hear distortion?

It may be possible that your external amp has low input sensitivity and your X3300W's output is muted. If in doubt, do a factory reset that takes a few seconds, then try again.

 

[olddog]

Thanks. Will try.

Couldn't they just come up with a SINGLE button called "RESET" where you can just press ONE button and hold the button for a few seconds and then it asks you if you really want to reset everything to factory?

I don't have kids and while this method would work for me....

BTW, my AVR-3312 is doing the same thing - static noise through the speakers, but okay when using the internal amps.

I already tried the reset.
