Mackie MDB-1P Passive Direct Box
Key Features
  • Connect an Instrument to a Mic Input
  • Converts Unbalanced to Balanced
  • Converts High Impedance to Low Impedance
  • 1/4" Unbalanced Input
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.

A -15 dB pad reduces the input level to prevent distortion when using a high-gain source, and the ground-lift switch inhibits hum caused by ground loops. Due to its passive design, the MDB-1P requires no batteries or power supply. A sturdy steel chassis enables confident use in the studio or on the road.
