5 USB Audio Interfaces / Preamps for RE-20 & SM7B

The RE-20 & SM7B microphones are great dynamic solutions for audio engineers. Many podcasters and broadcasters rely on them to record audio. Most of us can’t afford expensive mixers or audio interfaces though. Besides, some of those expensive mixers are not compact or easy to carry around. Here are 5 portable USB Audio Interfaces / preamplifiers with enough gain for the EV RE-20 and Shure SM7B microphones:


Focusrite Forte: a pretty awesome USB interface for Mac and Windows platforms. It has 2 remote-controlled mic preamps from the RedNet range with phantom power, HPF and polarity reverse. It offers 75dB in gain.


RME Babyface Audio Interface: a premium audio interface with sample rates up to 192kHz on all I/O. The included software is pretty sophisticated too. The preamps are very clean.


Apogee Duet: a pretty popular audio interface among Mac fans. It offers up to 75dB of gain. You get clean output and compatibility with Logic, Soundtrack Pro, Final Cut, or GarageBand.
