Default Eleven Rack Buzz

I recently bought an 11 Rack Bundle from Sweet Water, comes with (Pro Tools/11 Rack) and it was working amazing for the first 3 weeks. Then it started buzzing on every setting, regardless of it the 11 Rack was hooked up to Pro Tools or stand alone. I contacted sweet water and they replaced it with a new unit, only it start doing the same thing. I've tried different outlets through out my house, guitar cables, guitars with no help to solving the problem. Here are 2 links, one a recording of before this started happening and one with the buzz.

P.S I've always tried different settings within the 11 rack and an external noise gate.

Can't help because soundcloud says it can't find the sounds and that maybe I was trying to look at a private file.

Could you possibly try plugging the unit in somewhere else to rule out a bad power source?

I was in an apartment for a while that a couple of outlets had extra noise coming through.

I figured out the problem, as crazy as it is it was the light in the next room over causing it. Which I can't believe because I tried everything, from different locations and outlets, turning off the lights in the room, but it came out to be lights in a completely different room. My biggest concern now is this an electrical issue in my house, or a problem with the 11 rack itself. I've owned many units before and have never had such a problem.

You more likely than not do not have an electrical issue as such in your house that an electrician can fix. Not knowing exactly what lights and such you have it can readily be something like lamp dimmers, flourescent lights, compact flourescent lights, even an old crt tv or crt computer display. Noise like this is not something that can be fixed by reworking the wiring. You cite several good fixes such as ferrite cores on cables, etc.

If you really need help contact a local ham radio (amateur radio) operator near you and he or she will probably be able to help you really get this sorted. I should know as I'm one and I've had to solve any number of strange issues like you have. That being said I'd like to hear what the sounds are like but as I said earlier I can't because soundcloud says it cant' find the files.

Flouresent light? Was it on a wall dimmer? both of those can add noise. You might try a ferrite choke on the line cord. You can find them at Radio Shack. Its a big iron inducter you wrap the cord around. Some USB cables have them also. they are the ones with the cylinder on the built into the cable. Most of Avids interfaces have them.

I'll re-post them as soon I get, as I had taken them down since the problem was solved.

Yes it was a dimmer light, it controlled all the lights in my living room. The lights are those new eco friendly, super cheap 30 watt bulbs.

CFL Flouresent or LED?

My guess is the Wall Dimmer.

GreenLite CFL Light Bulb 13w = 60w, also I probably shouldn't be using none dimmable lights on a dimmable switch >.>
