BOSS DI-1 Active Direct Box with Phantom Power, Phase Reversal and Ground Lift (DI-1)

BOSS DI-1 Active Direct Box with Phantom Power, Phase Reversal and Ground Lift (DI-1)

The BOSS DI-1 is a professional active direct box designed to convert high-impedance, unbalanced instrument signals into low-impedance, balanced signals for connection to mixing consoles and other professional audio equipment. It provides clear, accurate signal transmission while maintaining excellent sound quality across a wide frequency range.

The DI-1 uses active circuitry to provide a broad frequency response compared with conventional transformer-based direct boxes. It can operate from a 9-volt battery or phantom power supplied by a mixer, giving performers and audio engineers flexible powering options for both live and studio applications.

Three selectable input level switches allow the DI-1 to accommodate different signal sources. Phase reversal and ground lift switches provide additional control for managing signal polarity and reducing potential ground-loop noise. Its compact and durable design makes it a practical choice for professional audio systems.
