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: XLR di box
Match the input to your source
Input type decides whether a DI box fits the source you connect. The Mackie has a 1/4 inch high-impedance input, the Riworal has dual 1/4 inch stereo inputs, and the SQFOR has combo inputs for XLR and 1/4 inch plugs. Check the plug type on your source first, then pick the box with the matching input.
Check ground lift and hum control
Ground problems show up as hum in the signal path. The Mackie and the Riworal have a ground lift, and the SQFOR severs the ground connection between 2 pieces of equipment as a ground loop isolator. If hum appears when you connect two pieces of equipment, pick the box that addresses the ground connection.
Decide between passive and active
Passive boxes need no external power supply, while active boxes use power for their circuits. The Mackie and the SQFOR are passive boxes, and the Riworal is an active box that powers over a 5V Type-C jack or a 9V battery slot. Pick passive for a simple path with no power supply, and pick active when the box needs power for its features.
