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. ## Features - Connect your computer directly via USB - High-resolution 24bit/96Khz interface - Balanced XLR outputs with ground lift - Powered by your computer ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B079C74WJB | | Best Sellers Rank | #14,079 in Musical Instruments ( See Top 100 in Musical Instruments ) #34 in Recording Signal Direct Boxes | | Compatible Devices | Headphones | | Customer Package Type | Standard Packaging | | Customer Reviews | 4.7 4.7 out of 5 stars (505) | | Date First Available | January 27, 2018 | | Global Trade Identification Number | 00663961054019, 06639610540190 | | Is Discontinued By Manufacturer | No | | Item Weight | 1 pounds | | Item model number | MDB-USB | | Manufacturer | Loud Technologies, Inc. | | Number of Items | 1 | | Operating System | Windows | | Product Dimensions | 3.4 x 5.8 x 1.5 inches | | Style | Signal Direct Box | | Supported Software | WDM,MME,CoreAudio,DirectSound,WAV | | UPC | 663961054019 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Mackie - **Connectivity Technology:** USB - **Frequency Response:** 96 KHz - **Model Name:** MDB-USB - **Mounting Type:** Tabletop Mount ## Images ![MDB Series, USB Signal Direct Box (MDB-USB) - Image 1](https://m.media-amazon.com/images/I/618goL5efLL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great *by A***2 on June 2, 2025* Quality is really good.
