Every aspect of our direct boxes are designed for maximum sonic integrity, from the custom-wound CineMag USA transformer to the rugged metal knob and switches. You can expect warm, rich tone even after long cable runs, and the extruded aluminum enclosure ensures a long life span. When you need to convert an instrument-level signal to mic-level, with sonic quality as your top priority, you'll be well-served with the Direct Box Passive from Warm Audio.
