Backed by us. Trusted by you.
Victory isn't given. It's earned.
We build our own instruments and carry the pro audio and video brands we trust, for everyone from first-timers to working pros, from your garage to the big stage. Started in 2017.
WA-DI-A is an active direct box with a CineMag transformer, converting a high-impedance instrument signal to balanced low-impedance mic level. Active means it is powered, so passive pickups see a high input impedance and keep their top end instead of losing it into the cable.
Passive pickups stop sounding dull the moment they see the right impedance.
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 the Direct Box Active and Direct Box Passive from Warm Audio. 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 Active and 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. Features include: · Custom-wound CineMag USA transformer · Converts instruments to mic-level signals without signal degradation · Ideal solution for plugging your instrument direct into any mic pre, mixer or recording device · Top-quality discrete components with gold-plated traces on circuit board · Rugged aluminum chassis construction · Pad: Variable from -3dB to -30dB · Balanced Output: 600 ohms, mic level · Input Impedance: 1 Meg Ohms · THD: .01% from 20Hz to 50Hz; Less than .003% from 50Hz to 20kHz · Frequency Response: 10Hz to 90kHz +/- 0.5dB · Linear Performance: +/- 0.05dB 20Hz to 50kHz · Power: 48V Phantom or two 9V batteries; Can also be used passively

Active or Passive DI, Which Do I Need?
Active for passive pickups, which need a high input impedance to keep their top end. Passive for active pickups, keyboards and any source with a strong buffered output. Using the wrong one is the most common reason a DI signal sounds flat.
Why Does a DI Box Need a Transformer?
The transformer balances the signal and provides galvanic isolation, which is what removes hum and ground loops when the instrument and the desk are on different circuits. CineMag builds the transformer here.
Does It Need Phantom Power?
An active DI requires power, normally 48V phantom from the console or interface it feeds.
Why Warm Audio
Warm Audio builds recreations of the classic studio hardware most engineers will never get to own, at a fraction of what the originals cost. The company sources premium components, CineMag and custom transformers, Fairchild-grade capacitors, NOS tubes where the design calls for them, and puts them into circuits copied closely from the originals rather than approximated. It has grown from microphones and preamps into compressors, EQs, direct boxes, guitar pedals and cable.
