A direct box (also called a “DI box” or simply “DI” for direct inject or direct input) is a device that converts unbalanced, high-impedance outputs to balanced low impedance. This allows for longer cable runs without compromising audio quality by adding noise. Most direct boxes are equipped with at least one input and two outputs: One input can be connected to an instrument amplifier, while the other connects to a PA system.
Direct boxes are basically transformers, bridging between inputs and outputs via electromagnetic induction. Direct boxes can be passive—meaning they do not require power to operate—or powered (active)—which are akin to preamplifiers by boosting signal power. Some specialty direct boxes are also available, each of which adds specific functionality to your audio setup.
Whether you’re setting up a stage, fitting out a recording studio, and anywhere in-between, direct boxes offer huge benefits to improving your sound and streamlining your audio chain. They enhance the sound of vocals and instruments via microphones, electronic instruments, etc., while sending improved signals to electronic devices such as keyboards, smartphones, and laptops.
For a direct box that meets your technological needs without breaking your budget, look no further than Sound Productions’ assortment from Palmer, Radial Engineering, Whirlwind, and more!
