Warm Audio WA-DI-P Passive DI Box

Warm Audio’s active and passive DI boxes are designed and built to deliver premium performance, from the inside-out. On the inside, you’ll find 100% Class-A circuitry using premium components, but the star of the show is a custom USA-made CineMag transformer, included in both passive and active models. The transformer ensures 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 via dual 9v batteries. The active DI can also be switched to passive mode for added versatility.

Warm Audio DI Boxes allow you to run the high-impedance signals from guitar, bass, and keyboards directly into low impedance mic preamps, mixers, interfaces or to send signal over extended cable runs without losing volume, tone, and significant high-frequency information. 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.
