The Mackie MDB-2P Stereo Passive Direct Box is a piece of professional audio gear used to connect stereo unbalanced audio sources like keyboards, media players, and other line-level instruments to balanced audio inputs on mixers, amplifiers, and other audio devices. The MDB-2P is a passive device that transforms an unbalanced stereo signal to a balanced mono signal using two transformers, delivering excellent audio quality and minimal noise. It has two 1/4″ inputs, two parallel outputs, and two XLR outputs for varied connection. The MDB-2P also has ground-lift switches to prevent undesired hum and buzz, as well as a sturdy all-metal chassis for dependable operation in a variety of environments.
Affordable 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 passive analog circuitry gives each channel of the Mackie MDB-2P a musical, linear response. Dual -15dB pads protect inputs from high-level sources such as active pickups, laptops, and mobile devices, while a Ground Lift switch eliminates grounding loop issues you may encounter in the wild.
