Warm Audio WA-DI-A Active Direct Box

The Warm Audio WA-DI-A is a premium active direct box designed for exceptional versatility and pristine signal conversion. It features a unique onboard variable pad knob that attenuates your input signal from -3 dB to -30 dB, making it easy to handle any instrument source with precision.

Equipped with a Thru-put jack linked to the input, you can send your instrument’s signal to multiple destinations simultaneously, such as a live mixer, recording interface, or secondary amplifier. The WA-DI-A can also take a recorded line-level signal and route it to another line input while sending a balanced mic-level signal via XLR.

Ideal for connecting electric guitars, basses, keyboards, and drum machines directly to a PA or recording system, this DI box converts high-impedance, unbalanced signals into low-impedance, balanced signals—delivering proper voltage levels for clean, distortion-free audio.
