MDB Series Direct Boxes

Hookup Diagrams

  The MDB-2P direct box works great for musicians with stereo instruments. In this example, we connected 

a synthesizer to the MDB-2P left and right input jacks. The thru jacks are then connected to the keyboard 

amplifier’s input jacks. 

  Unlike the other MDB Series Direct Boxes, the rear panel  of the MDB-2P has dual L/R output jacks for 

connecting XLR cables between the MDB-2P and a mixer’s input jacks.

  Your fantastic fans await your memserizing music and tasteful tunes. Time to stop reading...

  Note: While we used a Mackie ProFX12v2 mixer in this example, you could connect the outputs of the MDB-2P 

to the input jacks of an audio interface instead. The Mackie Big Knob Studio and come to mind!
