Description

Mackie MDB-1P Passive Direct Box

Di Box หรือ Direct Box แบบ Passive Mackie MDB-1P, Converts Unbalanced to Balanced, Converts High Impedance to Low Impedance, 1/4″ Unbalanced Input, XLR Balanced Output, Switchable Pad Prevents Overloading, Ground-Lift Switch Minimizes Hum, No Power Source Required

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.

Features:

  • Connect an instrument such as a guitar, bass, or keyboard to a microphone preamp
  • Converts a high-impedance, unbalanced 1/4″ input to a low-impedance, balanced XLR mic-level output
  • 1/4″ thru jack for routing to an amplifier
  • -15 dB pad prevents overloading when accepting signal from a loud source
  • Ground-lift switch minimizes hum
  • Passive design requires no batteries or power supply
