Preserve Your Tone
Warm Audio’s active and passive DI boxes are designed and built to deliver premium performance, from the inside-out, in both mono and stereo. On the inside, you’ll find 100% Class-A circuitry using premium components, but the stars of the show are the custom USA-made CineMag transformers, included in both passive and active models, and on each channel in stereo. The transformers ensure that any analog color and character from your instrument or signal chain is preserved before hitting any mixers or audio interfaces. On the outside, a selectable -3 - -30dB pad helps dial-in your ideal signal volume and ground/lift switch helps eliminate ground-loop noise. The active version adds 48v phantom power that passes through from the mixer or interface source. The active DI can also be switched to passive mode for added versatility.

Pro Direct Sound: Studio & Stage
Warm Audio DI Boxes allow you to run high-impedance signals from guitar, bass, and keyboards in mono or stereo directly into low-impedance mic preamps, mixers, and interfaces, or send signal over extended cable runs without losing volume, tone, or high-frequency detail. Warm Audio's road-worthy DI Boxes are the professional solution for this common mismatch, ensuring you won't diminish the tone of your instrument or performance.

What You Need To Know
Like premium DI boxes costing 2-3X, Warm Audio active and passive DIs include all the features and rugged build expected to deliver a complete and professional audio experience.

The variable pad on the DI boxes is designed to help properly set levels from the DI to the mixer or audio interface. If distortion is audible, engage the pad and begin to apply attenuation until the signal is loud and clear.

The Phase switch reverses the polarity of the signal, correcting potentially poorly wired cables and eliminating phase-related noise issues.

The “instrument” setting on the switch works with all types of instruments using ¼” outputs. When using a signal from a guitar amplifier is desired, switch to “amp out” switch to send your amplified guitar signal to the DI and then out via the XLR output. **

Eliminate noise like hum and buzz caused by ground-loop issues. As more pieces of equipment connect to various power supplies, the chance of ground-loop hum issues increase.
**WARNING: Most guitar amps require a reactive load (a speaker) to be connected to the amplifier to prevent overheating. The best practice is to connect a ¼” cable to the ‘THRU’ input directly to a properly rated speaker cabinet. This ensures the amp is loaded properly, preventing serious damage to your amplifier.
ACTIVE ONLY - ACTIVE/PASSIVE SWITCH: The active version of the DI has LED indicators to show if 48v is being passed from the connected device - such as mixers, interfaces, or stage boxes. The active/passive switch changes the operational mode of the DI from active (power engaged) or passive, using no 48v power.
