buzzzzz

can anyone please help me stop a loud constant buzz coming from my rather oversized speaker / amp setup

 

Could well be an earth loop - is it coming from both speakers? does it get louder if you turn up the volume? Is it the same on every source?

 

yes yes and yes

 

Is a transistor or valve amp?

 

Think its transistor.

Is this a game of 20 questions?

It's an earth loop.

 

ok so what do i do about it? is it caused by a duff lead?

 

Is it hum or buzz?

Ground loop is something I'd describe as hum due to 50hz cycle.

If it is ground loop then read this for all the info you'll need to safely fix it. If your amp is fitted with a ground connect(virtually all are) do not remove the ground wire from your amp as its unsafe and illegal.

If your having trouble differentiating between hum and buzz there's one sure way you'll be able to identify. No doubt you've heard one of these in action(seeing one in action is another matter entirely) and if your noise sound like this then you have buzz:

 

in that case its def hum. cheers ill try the link
