ART DualZDirect 2-Channel Dual Professional Passive Direct Box.

When you need a reliable way to connect instruments, line-level gear, or even speaker outputs to a mixer without noise or signal loss, the DUALZDirect is a smart, professional solution. This dual-channel, fully passive DI box is designed to deliver clean, balanced audio in live sound, studio, DJ, and fixed-install applications—without the need for power or batteries.

Each high-impedance 1/4″ input is converted through high-performance audio isolation transformers into a balanced, low-impedance output. These transformers offer a wide, flat frequency response and handle high signal levels with ease, ensuring a neutral, accurate sound even over long cable runs and in challenging, high-noise environments.

The DUALZDirect is built with practical features that make setup simple and flexible. Input attenuator switches allow you to match different signal levels, while THRU jacks let you tap into your signal chain without interruption. Ground lift switches provide complete isolation between input and output grounds, helping eliminate hum and ground-loop noise when connecting multiple systems.

To go beyond standard DI functionality, the DUALZDirect includes switchable low-pass filters that reduce high-frequency and radio interference before it reaches your main system. These filters are especially useful when interfacing with computer-based audio sources. Phase invert switches are also included, giving you instant polarity control—ideal when blending direct signals with microphone feeds.

All of this is housed in a compact, black-anodized aluminum enclosure built for durability and long-term use. With its passive design, solid construction, and professional feature set, the DUALZDirect is a dependable tool you can count on in almost any PA setup.
