Mackie MDB 1A Active Direct Box Mono

The Mackie MDB-1A is an active direct box designed to connect a single instrument such as a guitar, bass, or keyboard to a microphone preamp for musicians and audio engineers in recording sessions, houses of worship, and live stage applications. It converts a high-impedance, instrument-level signal via its 1/4″ TS unbalanced input to a low-impedance, mic-level output via its balanced XLR 3-pin jack. A 1/4″ thru jack allows simultaneous connection to an amplifier or pedalboard.

MDB Series direct boxes are built to last with a thick steel chassis, impact resistant corners, and long-wearing jacks will keep these in your bag for years to come.

MDB Series direct boxes offer excellent noise performance and transparency. Whether you are in the studio or performing on stage, your instruments will always sound as good as they do at the source.
