ART Passive DI Box

The ART Passive DI Box is a high-quality audio interface designed to seamlessly connect instrument, line, or speaker-level signals to a professional mixer or any other balanced input. Its core is a high-performance audio isolation transformer, which effectively eliminates ground loops, reduces hum and buzz, and protects sensitive equipment from potential damage.

This versatile unit features a high-impedance, single-ended ¼-inch unbalanced input, accommodating a wide range of audio sources from electric guitars and keyboards to speaker outputs. It delivers an extremely flat and wide frequency response, ensuring your audio signal is transferred with pristine clarity and fidelity, preserving the original tonal characteristics of your source.

For maximum flexibility in any setup, the DI box includes several essential controls. A ground lift switch helps to eliminate troublesome hum caused by earth loops. A switchable low-pass filter is on hand to tame excessive high-frequency noise or brightness. Furthermore, a phase invert switch allows you to correct phase issues when combining multiple audio signals, ensuring perfect alignment in your mix.

Conveniently powered, the unit operates directly from a standard UK mains plug (Type G). This plug type is commonly used throughout the United Kingdom, Ireland, Cyprus, Saudi Arabia, Malta, and many other regions, making it a practical choice for both domestic and international use. Its compact and robust metal housing ensures durability for studio work, live performances, and touring.
