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 superb ground-lift switch, and the 3-position input attenuator can accommodate input levels of up to +48 dBu. This handy built-in attenuator also allows you to connect directly 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.
