The Warm Audio WA-DI-P is a high-performance passive direct box designed to convert high-impedance unbalanced signals to low-impedance balanced signals without the need for external power. It features a custom-wound USA-made CineMag transformer that delivers a rich, analog character while preserving signal integrity. The unit is equipped with a unique variable pad knob, allowing users to attenuate input signals from -3dB to -30dB for optimal gain staging. Additionally, it includes a phase reverse switch and a ground lift to eliminate common interference and hum issues. Built with discrete components and gold-plated traces, the DI is housed in a rugged aluminum chassis suitable for both studio and live environments.
