The Mondial Magic Block cost $90 at AudioAdvisor. I know there are other vendors that manufacture a similar device for less money. Enjoy, TIC

It worked for me for years but seemed to interfere with my DMX reception. However, when I removed it, the hum returned. My cable technician, despite professing ignorance of anything like cable-related ground loops, did agree to relocate and link the cable ground to the main ground. Voila! No need for the Magic box or any other. No hum, either. Kal (who prefers to fix the problem, not cover it up)
