Warm Audio WA-DI-P2 Transformer-Balanced Passive Stereo DI 2-Channel Direct Box

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.

Electirc Guitar

Direct Electric Guitars

Record mono/stereo electric guitars direct to audio interfaces with both passive & active DIs. Active DIs work great with passive electric guitars that don’t have active pickups.

Electric Bass

Direct Bass Signals

Send clear, balanced signal from mono/stereo bass guitars even while plugged into a bass amp. Use active DIs for passive basses and passive DIs for basses containing battery packs.

Electric Keys & Synths

Keys For Stage & Studio

Take unbalanced stereo or mono keyboard outputs and convert to clear, balanced signals for recording or FOH.

Acoustic Guitar

Direct, Clear Acoustic Guitar

Use passive DIs for active electric-acoustic guitars (with batteries) and active DIs for acoustic guitars with external passive pickups.

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.
