  • Sale
  • Regular price $79.99

Mackie MDB direct boxes are acoustically transparent and ruggedly built to ensure that your instruments and audio sources arrive at your listeners clean, uncolored, and as expected. Premium active analog circuitry (requires phantom power) gives the Mackie MDB-1A exceptional headroom and clarity. A -20dB pad protects the input from high-level sources such as active pickups and mobile devices. There’s even a Merge switch, which permits the connection of stereo audio sources, like keyboards, and sums them down to a single mono output. And with standard features like Low Cut, Ground Lift, and Polarity switches, the Mackie MDB-1A Active Direct Box from Sweetwater is equipped for whatever challenges your performance environment can throw at you.
