Applies to: Scarlett 3rd Generation
By default, all 3rd Generation Scarletts will disable 48V (phantom power) upon turning the device off.
This is a safety feature we included to help prevent accidental damage to Ribbon Microphones which can be damaged when Phantom Power is applied to them.
Many modern microphones are not affected by 48V, however, if you are concerned or not sure; please consult that microphone's user guide or manufacturer.
Starting in Focusrite Control 3.6.0 we have added the ability to "Retain 48V" for all 3rd Gen Scarletts.
When Enabled, "Retain 48V" will make it so Phantom Power retains it's last used setting. If left on, 48V will remain on when restarting the interface.
When using Ribbon Microphones we still recommend leaving this setting disabled to protect against any accidental damage.
