[QUOTE="Ingvar Ahlberg, post: 816658, member: 15447"] Sorry, unclear and maybe even not read entire thread carefully. Protective ground/earth is an entirely different thing than the ground we are trying to find problem point causing hum. Protective earth/mains grounding is allways the same thing, no matter if power (live wire) supplying equipment comes from different phases of incomming power, protective ground is the same. This can be connected to ground/signal ground in some music equipment, in that case the in/output connectors will surely be insulated from chassis, otherwise uncorrect designed. If You describe system layout i can try to guide the hum killing project a bit better. Ingvar [/QUOTE]
