Hi Guys, I'm new to these forums, so wanted to say hi. I have a question with recording. I'm looking at getting a large diaphragm condenser mic, specifically this one:http://www.zzounds.com/item--MSEV57M I understand that I need a phantom power source to run this baby, so I was looking at preamps. The ones with a USB out are twice as much as normal ones with a 1/4' or XLR out. I talked with the guys at the music store and they said that I could use a 1'4' to 1/8' converter and that would work. Then I called Apple, who said that there is no "optical input" for the macbook, hence the only way to record would be with a USB interface. What's the deal? What's the cheapest setup? Thanks for your help!
