Onstage and in the studio, the DI100 handles the all-important task of converting your unbalanced guitar, bass, and keyboard sources into the noise-free balanced signals your console wants to see. Thanks to the DI100’s pad, you can even connect it to the output of your guitar amp! Of course, you get a groundlift, and the internal battery shuts down when phantom power is applied. Great sound – in a road-tough aluminum case with stackable rubber corners.
