Hi everyone! I have been talking with some friends about doing a studio, and I am the one that looks like I'll have all the equipment. To start off I want to get some Rokit 5 monitors along with things like input for electric guitars and microphones. What I'm stuck on is a Audio Interface. I would like one that would be rack mountable and possibly FireWire, but I have no idea how I can get this kind of interface for less than $100 (I just am in a super tight budget and just want to make some room with Audio stuff). I have looked around a bit and have like no knowledge on Audio related stuff so maybe someone has advice for me! What I'd Like: FireWire/USB/Line-In/Optical Rack Mountable minimum of 2 XLR outputs minimum of 2x 3.5mm Input No more than $150 Works with OS X! Thanks!
