Question:
SM7B: Output is too low. What should I do?
Answer:

The SM7B is a dynamic microphone. A typical dynamic mic has a lower output level than a typical condenser mic. The SM7B in particular requires the use of a preamp. When selecting a preamp for the SM7B, make sure the preamp has a minimum gain of 60 dB. Many modern mic preamps assume the mic is a condenser mic with a "hot" output level. Thus, it is common to find mic preamps or mic mixers with gains of only 40 to 50 dB.
