Preamps, phantom power, interfaces
1Agreed with Eliya. Get external phantom power boxes...if you want 4-8 channels you ll probably need to get multiple devices as I think most of what s on the market is 2-channel boxes. Rolls makes one in the ballpark of $50 USD.If I was in your position I d use the Roland strictly for I/O and utilize the board preamps, but that s largely because I like to use my DAW as a black box with I/O and that s it. I don t know what your mic locker looks like but you d probably get more mileage from buying a higher-end mic to use with the board preamps than buying an expensive preamp to use with your existing mics (I say that assuming you dont have any mics that would be considered high-end). Also, you can get excellent no-frills preamps for not much money retail, and for even less if you get curious enough to try building your own from a kit.
