Introduction Introduction The Extron MDA 5 Series of Mini Distribution Amplifiers (MDAs) are a family of three video and audio distribution amplifiers. The MDA are members of the Extron VersaTools™ line of basic distribution amplifiers, switchers, and associated video accessories. The MDA 5V distributes buffered composite video, the MDA 5SV distributes buffered S-video (luminance [Y] and chrominance [C]), and the MDA 5A RCA distributes amplified stereo audio, on RCA outputs.
grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (such as the use of power strips). Rack mounting procedures For optional rack mounting, mount the MDA on a VersaTools 3.5" deep 1U Rack Shelf (Extron part #60-190-20) (figure 1) or a standard Universal 1U 9.5" deep Rack Shelf (Extron part #60-19001) (figure 2).
Installation Only products in the VersaTools line can be mounted to a VersaTools shelf. Any 1U rack-mountable Extron product can be mounted on the standard shelf. N Figure 2 — Mounting the MDA on the standard shelf Furniture or projector mounting Furniture mount or projector mount the MDA using the optional mounting kit (Part #70-212-01, furniture, or 70-217-01, projector) as follows: 1. Attach the mounting brackets to the MDA with the machine screws provided (figure 3).
2. If feet were previously installed on the bottom of the MDA, remove them. 3. For furniture mounting, hold the MDA with the attached brackets against the underside of the table or other furniture. Mark the location of the screw holes of the bracket on the mounting surface. 4. For furniture mounting, drill 3/32" (2 mm) diameter pilot holes, 1/4" (6.3 mm) deep in the mounting surface at the marked screw locations. 5. For furniture mounting, insert #8 wood screws into the four pilot holes.
