## Overview

The MDB-2P is a passive stereo direct box designed for professional musicians and audio engineers, featuring dual 1/4” high-impedance inputs with thru outputs, -15dB pads to prevent distortion, and dual low-impedance XLR outputs with ground lift. Its ultra-low noise design and rugged stainless steel construction make it ideal for live sound, recording studios, and electronic instruments like keyboards and synthesizers.

## Description

Great for stereo sources like keyboards and synthesizers, the MDB-2P is an essential tool for electronic musicians, live sound venues, and recording studios. The MDB-2P stereo passive DI features dual 1/4” high-impedance inputs with thru outputs and -15dB pads, and dual low-impedance XLR outputs with ground lift.

Review: Works great - Quality is really good. All connections work well and the sound is good. Great value.
Review: Solid performer from Mackie - I really like this particular model because I don't have to carry around spare batteries. Of course, you are reliant upon your mixer having phantom power, so that is an important limitation to be aware of if you are relying upon other people's boards. But if you are using your own board, this is a cool piece of hardware and has a lot of nice features like the 15db pad, the ability to combine two sources or use the second 1/4" jack as a "through" jack. I also like the ability to switch polarity and the ground lift. In addition, it feels like a solid little box that is well made. I've been using them for about a year now with no issues - just nice quiet signal.

- High-impedance 1/4" inputs with Thru outputs

## Questions & Answers

**Q: Can i use this for connecting the unbalanced l and r ts outputs from a drum machine into the balanced xlr inputs of two (left and right) speakers?**
A: Yes.  It is a two channel direct box. This device translates input from each 1/4" input to the associated XLR output.  You could do this with stereo L/R outputs or two separate instruments entirely.

**Q: Can I run 2 Keyboards in stereo thru this?**
A: It has two inputs and two outputs, imagine two very slim DI's attached together. So yes you can run stereo in but its going to be separate XLR outputs for L & R

**Q: Wondering if there is any bleed between left and right? We use loops with loops out right and a click our left to the board.**
A: There should be no bleed.

**Q: I don’t see the xlr out outputs on this unit??**
A: The XLR outputs are there. This direct box works great.
