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.

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.

Installation

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.
