The Shure SM7B can be intimidating at first and many people are wanting to set up their mic correctly. One of the first questions that people have when they setup their Shure SM7B is “Does the SM7B need 48v of Phantom Power.

There are two different answers to this question, depending on your setup.

Quick Answer: You do not need 48v of phantom power for the Shure SM7B unless you are using an inline preamp like a CloudLifter, Fethead, Dynamite, etc.

Phantom Power For Shure SM7B

Here the SM7B is pictured with the SSL2+ Audio Interface and does not require 48v.

The Shure SM7B is a dynamic microphone. Dynamic microphones use a magnet and a coil to generate electrical signal from the diaphragm of the microphone.

Adding 48v of phantom power will not improve the performance of the magnet and coil in any way whatsoever.

With most modern dynamic microphones, phantom power will not hurt them, but they also will not improve them. It is best practice to leave phantom power (48v) turned off, unless you need it turned on for a specific reason.
