The Behringer Ultra-DI DI20 is a DI (direct injection) box that can convert up to two separate unbalanced 1/4" TRS lines into two balanced XLR outputs, or function as a signal splitter. Guitarists, bass players and keyboard players will enjoy the simplicity and flexibility this little DI box provides. By flipping a switch, you can use the DI20 as a launching pad for two separate mono signals, a stereo signal – or a split-signal feeding two separate amps. The DI20 also features a ground-lift switch, and the 3-position input attenuator can accommodate input levels of up to +48 dBu. You can power the DI20 with either a 9v battery or your mixer’s phantom power supply (+18 to +48 V DC). The whole package is wrapped in an ultra compact and rugged metal housing. Features: Multi-purpose DI box for stage and studio applications Provides impedance and signal matching for the direct connection of instruments to mixers and amplifiers Converts 2 independent unbalanced 1/4'' TRS line inputs into 2 balanced XLR outputs Additional Split mode (channel 1 assigns signal to both XLR outputs) Ultra-flat frequency response due to servo-balanced operation Internal battery automatically shuts off when phantom power is applied Ground Lift switch eliminates typical ground loop problems Input 2 usable as channel 1 Link output (additional to XLR output) ¼“ TRS and XLR connectors Rugged metal case
