Warm Audio WA-DI-P Passive Direct Box

Whether you play guitar, bass, keyboards or another stringed instrument, you'll need a direct box that won't diminish your instrument's tone, like Direct Box Passive from Warm Audio.  Built around world-famous CineMag USA Transformer topology and engineering, like no other DI Boxes in the world. Constructed with top-tier discrete components housed in rugged aluminum chassis' that include switches, knobs and connectors that are all designed to withstand heavy abuse on the road or in the studio.

Made With USA Custom CineMag Transformers

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.

New DI Box Experience

Warm Audio DI boxes offer the rare versatility of having an onboard variable pad knob which attenuates your input signal all the way from -3dB to -30dB, which will easily tame any instrument input source.

The WA-DI-P Passive Direct Box offers a Thru-put jack that is jumpered to the input jack. It is a convenience jack allowing you to send your instrument's signal to a second place in addition to the live mixer or recording device. Our Direct Boxes can also take a recorded signal at line level and send it to another line input while simultaneously sending signal out of the XLR mic level output of the Direct Box.
