Understanding How Ferrites Can Prevent and Eliminate RF Interference to Audio Systems Jim Brown (K9YC) Audio Systems Group, Inc. Copyright 2005 Audio Systems Group, Inc. All rights reserved. Over the past few years, we ve been learning about some important mechanisms that can combine to cause radio frequency (RF) interference to sound systems. They are: 1. An audio cable will be excited as an antenna by radio signals that are nearby, and current will flow along its length. Most of this current will flow on the shield.
