hum in system, ground loon? 60hz?


I think I have what's called a groud loop hum. How do I get rid of it?

Hum is the level on both channels. What use alligator clips and wire to short? and which ones are 2 and 3? I think it's time to call my dealer and let him help. Thanks for all the comments!!!
I agree with Cornfed Boy that if indeed it is a Ground Loon you must shoot it before it mutates into human form. However, it could also be a Systemic Snipe, in which case you will need to have a Snipe Hunt...and there ought to be plenty of advice on this forum to lead you to Infinity and Beyond.
