The Behringer ULTRA-DI DI20 is a one-of-a-kind DI (direct injection) box that can convert up to two separate unbalanced 1/4-inch TRS lines into two balanced XLR outputs, or function as a signal splitter. Electric guitarists, keyboardists and bassists will love the flexibility this incredible 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. This handy built-in attenuator allows you to connect to your amplifier’s speaker outputs, even amps rated as high as 3,000 Watts. You can power the DI20 with either a 9 V battery or your mixer’s phantom power supply ( 18 to 48 V DC). The whole package is wrapped in an ultra compact, road-suitable and rugged metal housing. If you’re a working musician who demands uncompromising functionality and durability, the ULTRA-DI DI20 will astound you.
