Warm Audio DI-A Transformer-Balanced Active Direct Box

The Warm Audio DI-A Transformer-Balanced Active Direct Box is designed for use with electric instruments such as basses and guitars or acoustic instruments with preamps and 1/4" outputs. The design is based around renowned electrical components such as the custom-wound CineMag transformer at its core. With its rugged extruded aluminum enclosure, rugged metal switches, and Pad knob it will provide a warm tone over long cable runs as well as durability on the road.

Preserve Your Tone

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.

Pro Direct Sound: Studio & Stage

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.

Variable Pad

Attenuate your signal between -3 and -30 dB

Active Circuitry

Direct Box Active is best for instruments with passive pickups, especially acoustic instruments

Convenience Jack

The Direct Box Active offers a thru-put jack jumpered to the input jack; this lets you send your instrument's signal to a second place, in addition to the live mixer or recording device

Wired for Integrity and Durability

Every aspect of the Warm Direct Box Active is designed for sonic integrity, from custom-wound CineMag USA transformers, to metal switches and connectors, to gold-plated circuit traces
