Precautions
This symbol is intended to alert the user of important
operating and maintenance (servicing) instructions in
the literature provided with the equipment.
This symbol is intended to alert the user of the
presence of uninsulated dangerous voltage within
the product’s enclosure that may present a risk of
electric shock.
Caution
Read Instructions • Read and understand all safety and operating
instructions before using the equipment.
Retain Instructions • The safety instructions should be kept for future
reference.
Follow Warnings • Follow all warnings and instructions marked on the
equipment or in the user information.
Avoid Attachments • Do not use tools or attachments that are not
recommended by the equipment manufacturer because they may be
hazardous.
Warning
Power sources • This equipment should be operated only from the power source
indicated on the product. This equipment is intended to be used with a main power
system with a grounded (neutral) conductor. The third (grounding) pin is a safety
feature, do not attempt to bypass or disable it.
Power disconnection • To remove power from the equipment safely, remove all power
cords from the rear of the equipment, or the desktop power module (if detachable),
or from the power source receptacle (wall plug).
Power cord protection • Power cords should be routed so that they are not likely to be
stepped on or pinched by items placed upon or against them.
Servicing • Refer all servicing to qualifi ed service personnel. There are no user-
serviceable parts inside. To prevent the risk of shock, do not attempt to service
this equipment yourself because opening or removing covers may expose you to
dangerous voltage or other hazards.
Slots and openings • If the equipment has slots or holes in the enclosure, these are
provided to prevent overheating of sensitive components inside. These openings
must never be blocked by other objects.
Lithium battery • There is a danger of explosion if battery is incorrectly
replaced. Replace it only with the same or equivalent type recommended by
the manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.

Introduction
The Extron MDA 3 Series of Mini Distribution Amplifiers
(MDAs) are a family of eight one-input, three-output, video and
audio distribution amplifiers. The MDA series distribution
amplifiers (DAs) split one composite video or S-video input
and/or audio input for output to multiple destinations with no
loss of signal quality. The MDA are members of the Extron
VersaTools® line of basic distribution amplifiers, switchers, and
associated video accessories.
The MDAs distribute composite video, S-video (luminance (Y)
and chrominance (C)), and/or balanced or unbalanced audio on
captive screw connectors, or unbalanced audio on RCA
connectors, in the following combinations:

Figure 2 — MDAs mounted on a standard rack
shelf
Installation
The MDA 3 Series mini distribution amplifiers (DAs) can be
mounted on a rack shelf, to a rack without a shelf, under a desk
or tabletop, or on a projector bracket.
Rack mounting
For optional rack mounting, mount the MDA on any of the
following rack shelves:
• RSF 123 VersaTools
®
rack shelf kit (part #60-190-20)
(figure 1)
• RSB 123 VersaTools rack shelf (part #60-604-20)
• RSU 126 6" deep universal rack shelf kit (part #60-190-10)
• RSB 126 6" deep basic rack shelf (part #60-604-10)
• RSU 129 1U universal rack shelf kit (part #60-190-01)
(figure 2)
• RSB 129 1U basic rack shelf (part #60-604-01)
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.
1. If feet were previously installed on the bottom of the
MDA, remove them.
2. Mount the MDA on the rack shelf, using two 4-40 x 3/16"
screws in opposite (diagonal) corners to secure the MDA
to the shelf.
3. Install blank panel(s) or other unit(s) to the rack shelf.
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.

VersaTools® MDA 3 Series • Connections and Controls
Back of the rack mounting
The MDA can be mounted to the rear of a rack using the Extron
MBB 100 VersaTools® back of the rack mounting kit
(part #70-367-01) (figure 3). The kit allows the product to be
vertically mounted to the front or rear rack supports and facing
either towards the front or the rear of the rack.
Figure 3 — Attaching the back of the rack kit
1. Remove feet from the bottom of the MDA if they are
installed.
2. Remove two screws from one side of the unit. Retain the
screws for possible later reassembly without the bracket.
3. Attach one bracket to the side of the unit using the longer
screws included in the kit.
4. Repeat steps 2 and 3 on the other side of the unit.
5. Mount the unit to the rack using the two included rack
screws (figure 4). The MDA can be vertically mounted
facing in either direction.
Only VersaTools products and most IP Link products
can be mounted using the back of the rack mounting kit.

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 MDA slightly forward or
back, then tighten all four screws to secure the MDA in place.

Power (all models)
CAUTION
Power supply voltage polarity is extremely
important. Applying power with incorrect voltage
polarity could damage the power supply and the
MDA. Identify the power cord negative lead by the
ridges on the side of the cord.

Power connector — Plug the external 12 VDC power supply
into this 2-pole captive screw connector. The power supply is
included with the unit. Figure 12 shows how to wire the
connector.
CAUTION
Power supply voltage polarity is critical. Incorrect
voltage polarity can damage the power supply and
the MDA. Identify the power cord negative lead by
the ridges on the side of the cord (figure 12).

CAUTION
The length of the exposed (stripped) copper wires is
important. The ideal length is 0.3" (7 mm).
Longer bare wires can short together. Shorter wires
are not as secure in the captive screw connectors
and could be pulled out.
Use the supplied tie-wrap to strap the power cord to the
extended tail of the connector.
Your MDA may have shipped with a blue captive
screw connector. This blue connector can be plugged
into either a blue or an orange power receptacle.
The ideal length of exposed (stripped) copper wire
for the blue connector is 0.2" (5 mm).
The blue connector does not have the extended tail or the
included tie-wrap.
Do not tin the stripped power supply leads before
installing the captive screw connector. Tinned wires are
not as secure in the captive screw connectors and could
be pulled out.
To verify the polarity before connection, plug in the power
supply with no load and check the output with a voltmeter.
The two power cord wires must be kept separate
while the power supply is plugged in. Remove
power before wiring.
As an alternative, an Extron P/S 100 Universal 12 VDC Power
Supply, part #60-357-01, can power multiple MDAs or other
Extron 12 VDC devices using only one AC power connector.
