The 10 Best Direct Boxes
This wiki has been updated 6 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. By doing this, 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 selections, we may earn commissions to help fund the Wiki.
