Description

High-Resolution Stereo DI & USB Interface – Mackie MDB-USB

The Mackie MDB-USB Stereo DI Box combines a high-resolution USB audio interface with a professional stereo DI, offering ultra-clean and balanced outputs from digital sources. Designed for musicians, producers, and engineers, it converts computer audio into studio-quality analog sound, perfect for connecting laptops or desktops to mixing consoles, PA systems, or recording setups.

With a stereo input routed through dual balanced XLR outputs, the MDB-USB provides a Mono sum function, output level control, and a convenient headphone output for zero-latency monitoring. Bus-powered via USB, it requires no additional power supply or driver installation, making it a plug-and-play solution ideal for both live and studio applications.

Versatile Connectivity And Operation

The MDB-USB features dual XLR balanced outputs with ground lift for clean, low-noise connections to any professional audio gear. A mono switch allows stereo sources to be summed to mono if needed, and the integrated output level control ensures perfect matching with downstream equipment. The front-mounted headphone output provides a quick monitoring solution for tracking or stage use.

Designed with Mackie’s trademark rugged construction, the MDB-USB can handle the rigours of touring, rehearsal spaces, or home studios, delivering consistent, high-fidelity audio wherever it’s needed.
