How to eliminate buzzing in my setup

[frankieMART]

Hi all,

 

I have a Pro=Ject Debut II with a Pro-Ject MM phono box running into some fairly cheap Prodipe monitors and when I'm spinning I keep getting an annoying buzzing sound that I'd love to get rid of!

 

Could it be the ground pin on my phono box (see below) ? Is that in the correct place?

 

 

Failing that, I've noticed one of the gold connectors on my tonearm is slightly loose, could that be the issue?

 

Any help would be much appreciated!

 

Cheers

David

You don't happen to have any magnets close to either monitor, do you?

I'm not sure how project works it, but ever grounding spade I've seen gets put underneath that grounding post. Loosen it up, and tighten it down on the grounding terminal.

Chasing ground buzz is always annoying!  Try disconnecting from the ground and see.  Reconnect to the ground.  Try running ground wires from the tonearm base (maybe a screw holding the tonearm down).  Touch different areas of the tonearm...does the buzz go away?

 

Basically it's a hunt.

And only all of the above if it's just your table giving you problems. If you get a similar buzzing sound with your other sources, it might be interference from any other electrical equipment you have in your place. So it's definitely a hunt.

I think I've located the source of the buzzing, on my phono box the Right output socket is faulty, in that when it is plugged in it sounds like a dodgy connection. I've tried cleaning it with contact cleaner to no avial?

 

Best option to get a new phono stage?

Try a new cable between the phono stage and receiver.
