Power Problem

[gororbs]

Hi guys,
I'm hearing an electrical buzzing in my headphones. Last night I moved some gear into my living room and did a test. I sat on the ground and slowly moved my mic in different directions. I heard a loud buzzing in some spots and soft buzzing in other spots. Regardless, there was always a buzz.

Just so you know, I took my mixer to another location and it sounded clean. So I think it's the power in my house. All the outlets in my house produce this buzzing.

Would a power conditioner solve my problem? Any thoughts?
