Preserve the Tone of Your Stereo Source
Warm Audio DI boxes have earned a place in countless setups across Sweetwater, and we're thrilled to now offer them in stereo form. The Active Stereo DI with premium CineMag USA transformers is designed to preserve the tone of high-impedance stereo sources, such as piezo/under-saddle pickups, passive bass guitars, and other low-output sources. By converting their instrument-level signals into mic-level balanced outputs, the Stereo DI ensures your tone travels through mixers, PA systems, audio interfaces, and other preamps with its original sound intact. Furthermore, negative pads let you adjust the signal level across the entire chain, and Ground/Lift switches keep your signal clean. Also ideal for guitarists and keyboardists looking to send their stereo synths, modelers, amp sims, pedalboards, and effects rigs to front-of-house mixers and audio interfaces, the Warm Audio Active Stereo DI box is your rig's secret weapon for ensuring the audience hears your tone exactly as you intend.

Stereo for studio or stage
The Stereo DIs are available in both active and passive variants, and this active model’s selectable active circuitry is powered by +48V from your console or interface’s mic preamp input. Engaging this active circuitry enhances headroom, giving you more signal to work with before clipping. You can also engage the active circuitry on each channel independently, thereby blending a high-impedance signal on one channel with a low-impedance signal on the other. This is especially useful for acoustic guitarists looking to streamline their setup by blending their high-impedance guitar pickup signal with a low-impedance microphone signal using only a single box. The Active Stereo DI can also go fully passive with a simple flick of a switch, allowing it to handle hot sources and remain functional when +48V phantom power isn’t available.


Premium CineMag USA transformers
Both active and passive Stereo DI models are equipped with top-tier CineMag USA transformers, delivering rich clarity across the audio spectrum. In fact, both models’ frequency responses range from 10Hz to an incredible 100kHz. Coupled with their excellent noise rejection, the Warm Audio Stereo DIs will guarantee that no aspect of your sound gets lost in the signal chain shuffle.
