Apogee Ensemble Hiss Noise / Electrical Noise While Recording

I've been recordings with my Apogee Ensemble lately and have noticed quite a bit of noise coming from Mic input 1. This is different than some of the other threads who are noticing hiss noises through the output/headphone outs. It seems to be more of a white noise / electrical buzzing.

I'm wondering if this is the unit itself, or an actual problem with my electrical outlet... I noticed if I turn the dimming lights up and down in my studio that it can effect the level of the buzzing noise in examples 2 and 3... I'm thinking maybe I need to call the electrician over to reconfigure a couple of the outlets I run my equipment into. Has anyone here run into problems like these, and if so, what are your thoughts?

If the dimmer is having an audible affect on your Ensemble, you need to find a separate, dedicated circuit for power. I am guessing that your outlet and dimmer are on the same circuit. Look at your breaker box to find out. Try running power to a different outlet. Usually you can find a dedicated utility outlet near your breaker box that will have nothing else wired in line with it. See if the noise goes away.

If this works and you have room in your breaker box, think about having the electrician run some separate 20amp outlets for your studio use only and ask him to put them on the same leg if possible.
