You can connect your Shure SM7B directly to the Focusrite Scarlett Solo 4th Generation without the need for a Cloudlifter or similar device. The 4th generation Scarlett Solo offers significantly improved preamps with a gain capacity of 69dB, which is enough to amplify the signal from the Shure SM7B, which is known to have a low output signal, and allow for clean recording. In addition, the Scarlett Solo 4th Gen has an auto-gain function that automatically sets the optimum recording levels, making the microphone even easier to use.
