Is This Problem My Amp

[Baron Von Doom]

im getting a strange sound through my rear speakers (mission m70) when watching sky i hear a strange sound over the other sounds. its very difficult to explain. it sounds like some sort of electrical distortion in time with the voices from the front speakers.
ive tried changing the speakers back to my old eltax ones but no difference.
is it likely to be the amp (yamaha rx-v350) or the sky box or something else?

It could be some glitchy processing that the decoders doing. Are you watching in PLII or DTS Neo? I found the other day i get a fizzling kinda eletrical noise, but only in the front and when my head was next to the speaker!

what mode are you using to process sky into multiple channels? PL2 or a yamaha mode/system?

 

[Baron Von Doom]

pro logic. im sure its only recently started doing this

More and more broadcasts are using higher compression rates nowadays, and this comes across as a funny noise, a little like Cher's singing....my money's on that.

The next time you hear it, play it in normal stereo. If you can still hear it, it's the broadcast, not the processing.

I can hear the same noises from my rears on many stereo broadcasts, using Prologic II. There aren't any noises with a true 5.1 source using DD.

Do you find that the noises happen mainly when the soundtrack is just dialogue, with no music or sound effects?
If so, it's a side effect of the PLII decoder trying to create surround information, and is perfectly normal. If you can hear it from your normal listening position, you've probably got the rear channel levels too high.
I can only hear the noises if I listen a few inches from the rear speakers.

Had the same issue from the fronts in PL mode, using a Marantz 7400 amp - problem cured when switched to either Neo or CSII ss modes. Guess it's an issue with the decoding....
