I've been looking for a solution to this problem for a long time.
And I'm not totally sure which forum I should put it in, so feel free to move it to another forum if needed.
First off. This buzz is not a hum. It's not low frequency.
Because of that I don't believe it is a grounding issue, which brings me to my next point.
I've tried using non-grounded outlets, which resulted in the same thing.
I'm using a 4.0 system. Dali Concept 6, Denon AVR-1909, and two older speakers. The buzz also occurs on my father's speakers Dali Ikon (number?) with Denon AVR-2808. As well as my PC speakers.
The buzz is increased when Audyssey Dynamic EQ is enabled. And the buzz is increased further more when increasing the volume.
I guess it is some type of electrical issue (so to speak). But I've tried almost everything.
- Different outlets.
- Non-grounded outlets.
- Keeping speaker-wires away from outlets.
- No input connected.
- All types of cables (HDMI, Coax..)
- Unplugged every antenna in the house.
- Tried with both Denon AVR-2808, 1909 and Onkyo TX-SR606
The reason it showed up when Dynamic EQ came on, is that the problem was a low frequency buzz. Dynamic EQ boosts the low frequency range as you turn the master volume down to compensate for human hearing.
The thing is that. This is more like a hiss, "sssssssss", and not a low frequency like a hum "hummmmmm".
It's a kind of old house. Not every room is grounded.
Is there anything else I can try? And tips?
Been searching around the Internet a lot. And there's probably some things I've tried that I've forgotten to list here.
Guess there might not be a solution to my problem. Except renewing outlets, cables and so on (in the house).
Help is appreciated.
