Warm Audio's active and passive DI boxes are designed and built to deliver exceptional performance inside and out. Inside, you'll find 100% Class A circuits with premium components, but the star of the show is a custom CineMag transformer, made in the USA, included in both passive and active models. This transformer ensures that the analog tone and character of your instrument or signal chain are preserved before reaching any mixer or audio interface. On the outside, a selectable pad from -3 to -30 dB helps dial in the ideal signal level, and a ground lift switch helps eliminate ground loop hum. The active version adds 48V phantom power via two 9V batteries. The active DI can also be switched to passive mode for added versatility.
