When I was searching for an audio interface for my SM7B and RE20 microphones, the Solid State Logic SSL 2 was one of the most recommended models on Reddit and other forums. The Solid State Logic SSL 2 MKII is the latest generation with enough gain to drive these dynamic microphones. It has 2 XLR mic preamps and up to 64dB gain range. There are balanced left and right outputs on the rear for your studio monitors.
This interface has a dynamic range of 120dB. It combines with the SSL Production Pack to help you produce studio quality audio content. The SSL 2 MKII has 48v phantom power and 4K legacy mode. There is also a UV meter, high pass filter and line-input selector that can be activated for each channel. This interface has a stereo loopback function.
