VCRs, surround processors, and any device that is connected to a television cable or satellite dish can
cause a loud buzz and should always be suspect. If, by the process of elimination described above,
you determine it is a component like a VCR that is causing the hum/buzz to occur, and using a cheater
plug doesn't help matters, it may be necessary to isolate the cable connection (CATV) with an isolation
transformer. This inexpensive device is available at most Walmart, Radio Shack or department store
type outlets and is sometimes called a 'matching transformer'. If you have problems fi nding one, call
your local cable TV company for advice. The matching transformer will be placed between the cable
TV cord and the VCR, TV or processor.
Just remember, take the system down to its simplest level of connection. Find a way to hook the
system up with as many pieces of the system missing or not connected. Keep it simple and get it
to the point where the hum's gone. Then start adding back components one at a time until the hum
returns.
Finding the problem is 9/10ths of the work in fi nding a solution.
