The Mackie MDB-1P is a passive 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.

THE PERFECT MATCH

With four models to choose from, you can get the perfect match for your instruments. Acoustic guitars and keyboards are right at home with the MDB-1P and MDB-2P.
