Multiple Altec 9440A amplifiers ground loops

[valhallax]

hey reed...
great to hear about your theatre again! im running anniversary series amps in mine.. and while i use a surround prossecor, i also run through a mixer, a splitter mixer , and active crossovers. tho i dont get hum, i do get a static crackle that seems to build up after hours of play.. a slight pop or crackle sound that only occurs very seldom. i attribute this to grounding issues as well. in my setup, i convert to balanced right out of the mixer.
can you give directions to the 12 page article on grounding?
and please repost the pics of your build on those 820's!..please

It was an 8 page article from Rane. They have several good articles about hum and grounding.
The article that I was referring to is at:
