Product Description

One of the 4 direct boxes available in Mackie's MDB Series, the Mackie MDB-USB is a USB stereo DI featuring a built-in high resolution USB interface. Requiring no driver, it can be connected to your computer via the Female type-B USB input, headphones via the 1/8" jack output, and a mixer, speakers or studio monitors via the dual XLR outputs with Ground Lift. This simple set-up allows you to stream audio directly from your computer and convert it into balanced stereo output with no noise or distortion. Once the computer has been securely and successfully connected, the power LED illuminates green and you are ready to go.

Premium Without the Price Tag
Direct boxes are an essential tool for any stage or studio. They make it easy to get clean, low-noise audio to a mixer no matter what instrument you are using. Available in four versatile models, our ultra-affordable DI's offer the Mackie sound quality that you expect with Built-Like-A-Tank construction for maximum reliability. From acoustic guitars to laptops, be ready for anything with MDB Series direct boxes.

Versatility - The Perfect Match
With four models to choose from, you can get the perfect match for your instruments. Acoustic guitars and keyboards are right at home with the MDB-1P and MDB-2P. High output instruments will appreciate the extra headroom in the MDB-1A.

Rugged - Built-Like-A-Tank
From the inside out, MDB Series direct boxes are built to last. Thick steel chassis, impact resistant corners, and long-wearing jacks will keep these in your bag for years to come.

Quality - Premium Analog Circuitry
MDB Series direct boxes offer excellent noise performance and transparency. Whether you are in the studio or performing on stage, your instruments will always sound as good as they do at the source.
