for various sound sources
READY TO GO
The Mackie MDB series is a direct box that can be used with a variety of sound sources, from acoustic guitars to laptop computers. We have four models available to choose from depending on your application. We support everyone involved in all kinds of music with the high-quality Mackie sound cultivated through analog mixers.

HIGH QUALITY SOUND
FUNCTION THAT EXCEEDS PRICE
A direct box is an essential audio tool both on stage and in the recording studio. The Mackie MDB series allows you to send any instrument to your mixing system with low noise and clear sound. We have four models available to choose from depending on your application. Both provide high-quality Mackie sound cultivated with analog mixers. Furthermore, it has a casing that is as sturdy as a tank, so it is safe even if it gets stepped on on stage. High-quality sound from acoustic guitars to laptops can be safely sent to PA systems.

4 MODELS TO CHOOSE FROM
We have four models available to choose from depending on the instrument and sound source you use. Please use the MDB-1P for acoustic guitars and the MDB-2P for synthesizers and keyboards.
The MDB-1A will be the best match for high-output instruments equipped with active pickups and preamps.

HIGH QUALITY ANALOG CIRCUIT
The MDB series direct box provides excellent noise suppression and provides clear and faithful sound whether on stage or in the recording studio.

OF COURSE
“TOUGH AS A TANK”
The MDB series direct box is safe even if stepped on on stage. The thick steel housing, highly durable design, and handles that protect the input and output sections ensure years of use.
