    Some of you may already know, but I'm an internet broadcaster. I broadcast video game tournaments around New Jersey for fighting games. Next month I'll be streaming Soulcalibur 5 and Tekken Tag Tournament 2 at North East Championships 2011. Below is an example of my work:



    However, while that broadcast was excellent... I do find I have issues at other venues; most likely due to the low quality of my gear and the power interference at the venues. The major issue I have is that at certain venues, there is a high pitched "hum" in the background of the audio... example below:



    We've come to the conclusion that this issue comes from two issues.

    Firstly, the headsets go straight into my Yamaha mixer through XLR, they don't go through a pre-amp. The problem with this is that the audio coming from the microphone isn't that loud, and in order to make it loud enough, I need to raise the gain on the line... and raising gain on the line not only amplifies the audio, but also the background noise.

    The second reason for this issue is the unclean power. I'm using the same equipment in the first video, and there is no hum. At this other venue, there is are neon lights (which you can see behind the commentators) plugged into the same line. These lights create AC to DC interference and so far I haven't found any success with any sort of "hum" killers.

    So because of these issues, I plan on building a new broadcasting rack, and I'm looking for advice from those who have experience in Pro-Audio for live events. Am I wasting my money? Is there something better I can get for the same price? Do I even need the pre-amp or the power conditioner? This stuff is expensive, so advice is appreciated.
