This wiki has been updated 7 times since it was first published in July of 2018. A direct box serves three main purposes: it transmits an electrical signal straight from the source, matches impedance levels, and balances the audio signal. As a result, it does away with ground loops and other technical phenomena that can cause buzzing and humming sounds during recordings or live performances. Our list includes the best available models from budget-tier to professional-grade. When users buy our independently chosen editorial picks, we may earn commissions to help fund the Wiki.

Editor's Notes

October 25, 2019:

DI boxes are categorically pretty simple; when they work, they work, and you can spend as little or just about as much as you want on a good one. Radial makes some of the best high-end options, and their Radial JDI Stereo is one of the best models on the market. The Radial USB-Pro Active is ideal if you're running a signal out of a laptop or other USB output, as it promises to be compatible with 24-bit sampling. Behringer, a huge player in affordable audio devices, also has a couple great choices. The Behringer DI20 is not only one of the lowest priced, it also has just about every feature you could need.

If you're willing to make a sizable investment, the Rupert Neve Designs Active is hard to beat, though it is very expensive. You can get by for far less with the Whirlwind pcDI or Whirlwind Imp 2, which are both very durably constructed. They're both excellent for integrating effects pedals a well as equalizers. And if all you need is a single, mono throughput, the Samson MDA1 is both affordable and highly effective.
