For rack mounting, do not install the rubber feet. Mount the
distribution amplifier on a 19" 1U VersaTools® rack shelf (Extron
part #60-190-20 or 60-604-20), a standard 1U Universal or Basic
rack shelf (Extron part #60-190-01 or 60-604-01), or a Universal
or Basic 6-inch Deep Rack Shelf (Extron part #60-190-10 or
60-604-10).
1. If feet were previously installed on the bottom of the
MDA, remove them.
2. Mount the MDA EQ on the rack shelf, using two 4-40 x
3/16" screws in opposite (diagonal) corners to secure the
unit to the shelf.
3. Install blank panel(s) or other unit(s) on the rack shelf.

into this 2-pin, 3.5 mm captive screw connector. The power
supply is included with the unit.
To wire the connector:
1. Cut the DC output cord to the length needed.
2. Strip the jacket to expose 0.2 inches (5 mm) of the
conductors.
Exposing more than 0.2" (5 mm) of the copper
wires could allow the stripped wires to touch each
