It works down to 12 VDC but does not meet all specifications. Power requirements: 48 V DC phantom power (5.6 mA).
Optional1Maker product pageshure.com/en-US/products/microphones/sm7dbRead 15 October 2026The page says an interface or mixer with +48 V phantom power is needed to operate the preamp, and the bypass switch reverts to the original SM7B performance. The user guide says the preamp needs +48 V and that the microphone works in bypass mode without it, so the value is optional.2Owner's manualpubs.shure.com/guide/SM7dB/en-USRead 15 October 2026Important: the SM7dB requires +48 V phantom power to operate with the preamplifier engaged. It will operate in bypass mode without phantom power.
