Operational Setup
1. Unpack the MD-0512, and accompanying V-PS6-1.2A power supply and physically inspect for any damage that
may have occurred during shipping. Also verify there is a small package with mounting accessories. Should there
be any damage, immediately contact Marshall Electronics at 800-800-6608. If you are not located within the
continental united states call +1 310-333-0606.
2. Install in your desired location. If wall mounting is required, attach the mounting brackets by removing the
Phillips head screws on the sides, closest to the rear of the unit. (See below) Only one screw per side should be
removed. Use the same screw to attach the bracket with the flange facing away from the side and parallel to the
front of the MD-0514 metal case. The flange has two holes. For desktop use, apply the supplied rubber pads.
