| I am using Behringer basically a multi amp or keyboard amp it has 5 channels a 15 inch speaker rated at 300 watts, has a lot of chorus settings and reverb settings I love the reverb and bass settings, only issue I have is setting it up with another amp, if I use two amps I get humming, this amp has digital settings and equalizer I just want to hook up to another amp without the low hum, somewhat annoying, but overall I like it. |

Steven, here is my advise, may or may not work.
Try to hook everything into the same grounded outlet. It creates a "STAR" ground. Good guitar cords with good conductive shields is essential. If the shielding is not conductive enough, you will get a ground loop. I just had a problem with "Live Wire Cables". The shielding on this brand of cable is not very conductive, meaning you have a poor ground. Each amp has it's own ground potential on the case. Sometimes the difference in ground potential creates a ground loop. Good luck. Let us know what happens? |

| Classic ground loop hum. I use two amps often use a Hum-X by Ebtech on one amp power cord to eliminate the hum |

I follow Keith's advice.
Plug all your amp(s), effects, etc. into a grounded Power Strip.
I use George L cables
Works for me.... |

That will not eliminate the ground loop. It is caused by both amps having grounded power cables and the two chassis being ground together by the shield of the instrument cables
This create a ground loop. The Hum-Ex will fix it. Another quick fix but unsafe is to lift the ground on one amp. The last method involves actually disconnect the instrument shield at one of the cables to one amp only at the end away from the amp. A method known in the pro audio world called "telescoping shields" |
