Isolated Ground causes ground hum.


Hi Experienced Goner.
I am adding the isolated ground into my music system and when I connected the ground wire into my existing system and it hums badly.
Did I do st wrong?
 Thanks

Please don’t add any ground rods yourself. 
Have a licensed sparky do it. I’m sure it won’t improve your current sq situation.
