Getting a clean signal from your instrument to a mixing console often requires more than just a cable. Direct boxes, or DI boxes, are essential for managing impedance and eliminating ground loop hum that can plague live performances and studio recordings. Our selection focuses on reliability, signal transparency, and build quality, ranging from compact passive units for mobile rigs to heavy-duty professional gear designed for touring.

Frequently Asked Questions

AI
Passive DI boxes use transformers and require no external power, making them ideal for high-output instruments. Active DI boxes require power (battery or phantom) and are generally better for low-output signals or piezo pickups.
If you are plugging into a mixer or audio interface over a long distance, a DI box prevents signal loss and removes the 60-cycle hum often associated with unbalanced cables.
The ground lift switch disconnects the shield of the input from the shield of the output, which is the primary way to eliminate buzzing caused by ground loops in your power system.
