Question about Harman Kardon AVR 300 Receiver
This condition started about a year ago. I thought the center channel speaker was damaged due to it being dropped. I replaced with a new Infinity PC250 and the distortion still exists. I connected the old Klipsch center speaker to another receiver and there is no distortion. The problem appears to be with the HK AVR300.

I'm not sure if this solution is still necessary however:
I own a H/K AVR300 and have a PS3 hooked up via HDMI to the TV and Optical TOSLink to the receiver. I have no troubles selecting between DD 5.1 and DTS 5.1. I can even select trueHD whatever format but I can't detect an audible difference, I think that mode might be downgraded back to regular DD5.1...
Hope this helps...

First try ensuring that "OPT 1, 2, or 3" function is selected depending which one you are using on the H/K 146 (see manual for selection instructions). Next please ensure that the PS3 audio out set to "optical" (Settings/sound settings/audio output settings/digital out+DD 5.1). That should help.

You seem have a problem with a component in that channel, the bad news is that it is hard to fix that type of problem (you would be better off if the channel died). All of the components in the final output section are part of the same audio loop (per channel), which makes it hard to find the faulty part.
Sounds to me like a bypass or coupling capacitor is faulty or need to be re-soldered, either way to fix this problem you should take it in to a repair shop.
I hope that helps and sorry for the bad news.

The protect message means that the outputs are shorted. This is a fairly common problem that can easily be fixed by any shop that handles audio gear. Expect a parts cost in the $20-$40 range.

Yes, there is something you can try, to know where to look for the problem if this happens again. If the receiver is still under warranty, just send it back, otherwise, open up the amp and trace the path back from the speaker channel to the capacitors on each channel, this is usually the problem(you should be able to see if it is blown, cheap to repair).
If all the channels went out at the same time, there is something wrong with the central unit, to repair that, if it is not the above problem, cost expensive.
Hope this can help you.
