The Switchcraft SC900CT is a professional direct box with a Custom transformer, and its ground lift switch can be controlled remotely using +48V phantom power from the console.
The unit can be operated in two modes—manual mode enables users to control the ground lift switch from the DI using the toggle switch, while phantom mode allows users to control the ground lift switch remotely using +48V phantom power from the console. When phantom power is engaged, an LED is illuminated, indicating that the ground is lifted. When phantom is turned off, the LED turns off indicating that the DI is grounded.
