Premium passive analog circuitry gives the Mackie MDB-1P a musical, linear response. A -15dB pad protects the input from high-level sources such as active pickups and mobile devices, while a Ground Lift switch eliminates grounding loop issues you may encounter in the wild. Thanks to its “Built-like-a-Tank” construction, the Mackie MDB-1P Passive Direct Box from Big Dude's is likely to earn a permanent spot in your gigging rotation.
