The units can be operated in two modes. Manual mode enables users to control the ground lift switch from the DI box. Phantom mode allows users to control the ground lift switch remotely using +48V phantom power from the console. When phantom power is engaged, a blue LED illuminates to indicate the ground is lifted.
Other key features include ease of use, fully shielded isolation transformers, optional Jensen transformer, recessed panels that protect the switches and connectors, and compact and rugged metal enclosures.
