Here is a recent question from one of our customers

Q I want to buy some of your TT10 TRS cables, are these the right cables for my studio monitors to run to my Mbox? The ones I have make annoying buzzing sounds. I really need balanced cables.

Answer

If your Mbox is buzzing there can be many causes of that, balanced cables help but they wont solve every issue.

 

Balanced cables work best when you have a very low signal, lots of electronic noise (lights) as they will shield out the noise by a process where the noise is introduced into both cable equally and then subtracted at the mixer.  

 

But if your noise is created by an earth loop they wont fix the issue at all. 

Some tips to fix earth loops

1. Try and use 1 earth for all electrical items in the signal path
2. Make your cables nice and short
3. make your set up as simple as possible first, then gradually build in extra layers of complexity, when one of the creates noise you will need to work out the cause and try and get rid of that.
