About Mackie MDB-1A

Before you take the stage or hit record in the studio, ensure your sound is captured in its purest form with the MDB-1A Active Direct Box from Mackie. Part of the MDB Series, this high-quality, durable direct box is designed to handle anything from acoustic guitars to laptops, faithfully transmitting your sound to your audience just as you hear it.

This innovative direct box is a professional audio tool that simplifies the process of delivering clean, low-noise audio to a mixer, regardless of the instrument you're using. The MDB-1A is equipped with a hi-z to lo-z transformer, accommodating a wide range of input and output levels, making it a versatile choice for various devices and applications.

The MDB-1A Active Direct Box stands out with its balanced XLR output, offering a more stable and reliable signal compared to an unbalanced 1/4" output. This feature is particularly beneficial in situations where the signal may be subject to interference or noise.

With the MDB-1A, you can expect the superior sound quality synonymous with Mackie products, thanks to its premium quality analog circuitry. This ensures excellent noise performance and transparency, allowing your instruments to sound as good as they do at the source, whether you're in the studio or performing live.

Constructed with a thick steel chassis, impact-resistant corners, and long-wearing jacks, the MDB-1A is built to last. It's designed with the rigors of the road in mind, ensuring it will be a reliable part of your gear setup for years to come.

The MDB-1A Active DI is also ideal for active instruments like guitars and basses with active pickups and preamps, offering increased headroom and distortion-free operation. It features a 1/4" high-impedance input and thru with a -20db pad, along with a Merge switch that turns the Thru jack into a second input, perfect for summing a stereo source to a mono output.

The balanced XLR output comes with switches for Polarity, Low Cut, and Ground Lift, providing you with maximum control over your sound. For added convenience, the MDB-1A is powered by 48v phantom power, eliminating the need for an external power source.

In summary, the MDB-1A Active Direct Box is a reliable, professional-grade tool that ensures your sound is delivered with clarity and precision, making it an essential addition to any stage or studio setup.
