Mackie MDB-USB Stereo USB Direct Box


Stereo USB to XLR Direct Box with Mono Switch

Stop using your laptop’s headphone out to feed a PA! The Mackie MDB-USB captures lush, 24bit/96kHz digital stereo audio from your computer and delivers it to a sound system via clean, noise-free XLR balanced outputs. The MDB-USB is Windows and Mac plug-and-play compatible, so whatever system you find yourself working on, there are no drivers to install or updates to manage. The MDB-USB gives you a Mono switch to fold down audio to a single channel (great for dialogue and samples) and a Ground Lift to eliminate grounding loop issues. A headphone out allows you to monitor audio in real time from the stage or soundboard. Thanks to its “Built-like-a-Tank” construction, the Mackie MDB-USB Stereo Direct Box from Sweetwater is likely to earn a permanent spot in your gigging rotation.
