That noise is most likely a ground loop. I've run into this a lot when using USB and audio devices. I'd say first, make sure you're using TRS audio cables to connect your brute to the audio interface. If you're still hearing hum try this guy. It's basically an isolation transformer that will break the ground loop. It has 2 channels, but you'll only need one for the microbrute. I've used a Behringer version (the linked one is cheaper) and and it worked like a charm. Hope this helps.
