[QUOTE="Rob Timmerman, post: 99648, member: 172"] Re: Help Identify this Noise? (example audio included!) Noise on line or neutral won't get past the power supply on a properly functioning piece of equipment (gear with nasty hum may be a different story). Noise on the ground conductor is a different story, although the impact of any such noise will depend on what is being done with the protective earth conductor within your equipment. Yo say you've eliminated every piece of gear as a source. How? By checking each one individually for the noise? What do your equipment interconnects and grounding look like? That you needed to filter out 60 cycle noise in your sample suggests that you may have some grounding/shielding problems, and this noise could be coupling in as part of those issues. [/QUOTE]
