Introduction
2
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.
The MDAs ship with external, desktop 12V power supplies,
which accept 100-240VAC input.
Installation
The MDA 5V, 5SV, and 5A RCA can be mounted on a rack shelf,
under a desk or tabletop, or on a projector bracket.
Rack mounting
For optional rack mounting, mount the MDA on a VersaTools 19"
1U Rack Shelf (Extron part #60-190-20) (figure 1) or a standard
Universal 1U Rack Shelf (Extron part #60-190-01) (figure 2). On
the standard rack shelf, the MDA mounts in one of four locations
to the rear of the rack or in one of four locations to the front of the
rack.

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. Tighten each screw into the mounting surface
until just less than 1/4” of the screw head protrudes.
6.For furniture mounting, align the mounting screws with
the slots in the brackets and place the MDA against the
surface, with the screws through the bracket slots.
7.For furniture mounting, slide the receiver slightly forward
or back, then tighten all four screws to secure the MDA in
place.
8.For projector mounting, secure the MDA to a projector
mount or other surface by inserting the mounting bolt
through the bracket’s slotted hole.
