How we ranked these di boxes
Every pick has at least 100 customer ratings on Amazon and a listing with real specifications. The order mixes two things: how each model compares on the specs below (higher share of the best value in this group scores more), and how widely it is bought. The spec score runs from 9.0 to 9.8 and only compares these picks with each other. A spec the listing does not state is left out and the other specs are re-weighted; a listing with fewer than 2 stated specs is scored at half. We do not test gear in person. Full method.
- Ground lift weight 2
- Pad switch weight 1
- Runs on batteries weight 1
Buying advice: di box for recording
Match channels to sources you record
A mono box takes one source, while a dual box takes two sources at the same time. The ART DualZDirect and the Mackie MDB-2P each give 2 channels, so they suit two sources tracked together. The Yovus and the Samson MD1 each give 1 channel, so count sources before choosing. If you record one guitar or one keyboard at a time, one channel covers the session.
Use pads and ground lift for hot signals
A pad switch softens a hot source. The Yovus, the Samson MD1, and the ART DualZDirect each give a pad switch. The Mackie MDB-2P gives 15 dB pads for the same job on a stereo rig. A ground lift fights buzz from grounding issues, and each of these five boxes gives a ground lift switch.
Check connections before you buy
A DI box should match the instrument output and the recorder input you already use. The Yovus takes a 1/4-inch instrument signal to a balanced XLR output, and the Samson MD1 sends a balanced mic-level XLR signal to mixing consoles or USB audio interfaces. The Donner unit sends a thru signal to an amp while its output goes to a PA system, so plan both paths before recording.
Frequently asked questions
Do I need a DI box to record guitar direct?
If you record an instrument signal into a balanced XLR input, a DI box matches the signal and gives a ground lift for buzz. The Yovus and the Samson MD1 each take a 1/4-inch instrument signal to a balanced XLR output.
What does a ground lift do on a DI box?
It helps fight buzz caused by grounding issues, and each box here gives a ground lift switch. Use it when buzz appears after connecting an instrument to a mixer or an interface.
Can one DI box record two instruments at once?
Yes, when the box gives 2 channels. The ART DualZDirect and the Mackie MDB-2P each give 2 channels, so they take two sources at the same time. A mono box takes one source.
Do passive DI boxes need power to record?
No. The Yovus, the Samson MD1, the ART DualZDirect, and the Mackie MDB-2P are passive designs that need no external power. The Samson MD1 circuit is entirely passive, and the Mackie design needs no power.
