The ULTRA-DI DI20 is an innovative active two-channel DI-box/splitter that takes the signal directly from an unbalanced high-impedance output—like an electric guitar—and feeds it directly into a mixing console or recorder. It is ideally suited to augment the traveling gear of musicians (especially guitar/bass players) as well as live/studio/broadcast engineers, installation contractors and studios/live event engineers. The DI20 converts two separate unbalanced 1/4" jack inputs into two balanced XLR outputs. There is a two-channel/link mode for flexible usage as mono, two-channel or splitter box. In link mode, channel 1 can be split up into 2 balanced XLR connectors plus 1 unbalanced 1/4" jack connector. Switchable input attenuation in three ranges allows input levels of up to +48 dBu, while a ground lift switch eliminates typical ground loop problems. It operates either by using a nine volt battery or by using 48 V phantom power. The whole package is enclosed in an ultra compact, road-suitable and extremely rugged housing.
