Introduction
The Extron P/2 DA2xi MT is a distribution amplifier that accepts video input from a VGA,
XGA, UXGA, or QXGA compatible PC and distributes the signal to separately buffered
outputs. The output on the back of the unit can be extended with Extron VGA Series cables
from 6 feet to 250 feet in length. The MT model also has audio input and output.
Features
•
Power and Signal LED — Green LED = power + signal. Amber LED = power but no
signal. Off = no power.
•
•
Gain and Peak DIP switch — Use this feature to compensate for longer cable runs.
Out Imp DIP switch — Changes the output impedance to be compatible with all
projectors.
•
Cable retention chain — The input cable can be secured to the unit with the supplied
chain (attached to the right standoff nut of the input VGA connector) to prevent the
cable from being lost or misplaced.

“Power and Signal indicator LED” on page 2), into this 2-pole captive screw connector.
The included power supply is shipped with a plug installed. If you need to cut the DC
output cord to a different length and reinstall the plug, refer to the following figure and

ATTENTION: Potential Damage to Property.
• Always use a power supply provided by or specified by Extron. Use of an
unauthorized power supply voids all regulatory compliance certification and
may cause damage to the supply and the end product.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air
handling spaces or in wall cavities. The power supply is to be located within
the same vicinity as the Extron AV processing equipment in an ordinary loca-
tion, Pollution Degree 2, secured to the equipment rack within the dedicated
closet, podium or desk.
• The installation must always be in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 75 and the Canadian Electrical
Code part 1, section 16. The power supply shall not be permanently fixed to
building structure or similar structure.
• When you connect the power supply, voltage polarity is extremely important.
Applying power with incorrect voltage polarity could damage the power supply
and the amplifier. Identify the power cord negative lead by the ridges on the
side of the cord.
NOTE: Do not tin the stripped power supply leads before installing the captive screw
connector. Tinned wires are not as secure in the connectors and could pull out. Strip
the power cord jacket 5 mm from the end.
CAUTION: Possible Electric Shock.
The two power cord wires must be kept separate while the power supply is plugged
in. Remove power before continuing.
To verify the polarity before connection, plug in the power supply with no load and check the
output with a voltmeter.

f Two-bank DIP switches — These switches affect only the video output ( ), not the
g
“monitor” output ( ). The Gain/Peak DIP switch should be on (up) when the output
d
cable is over 100 feet (30.5 m). The Out Imp DIP switch changes output impedance. If
all connections and operations are correct, but the output device has no picture, switch
to the other position.
g Video output connector — Connect the video output device (projector, display panel,
or monitor) to this connector.
h Audio output connector — Wire a 3.5 mm 5-pole captive screw audio connector as
shown below, and plug it into this connector. Connect the other end of the cable to an
audio output device or recorder.

ATTENTION: Potential Damage to Property.
Connect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-) terminal
will damage the audio output circuits.
i Local monitor cable assembly — Use this cable assembly to connect the local
monitor (video) and speaker (audio) to the unit. The chain is used to attach the cable to
the unit, to prevent the cable from being lost or misplaced.

Mounting
WARNING: May result in serious injury.
Installation and service must be performed by authorized personnel only (see
UL rack mounting guidelines below.
The P/2 DA2xi MT can be mounted on a rack shelf, under a desk or tabletop, or on a
projector bracket.
UL rack mounting guidelines
The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the
equipment in a rack.
1. Elevated operating ambient temperature — If installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack environment may be greater
than room ambient temperature. Therefore, install the unit in an environment compatible
with the maximum ambient temperature (Tma = +122 °F, +50 °C) specified by Extron.
2. Reduced air flow — Install the equipment in a rack so that the amount of air flow
required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mount the equipment in the rack so that a hazardous condition
is not achieved due to uneven mechanical loading.
4. Circuit overloading — Connect the equipment to the supply circuit and consider the
effect that circuit overloading might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used when
addressing this concern.
5. Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted
equipment. Pay particular attention to supply connections other than direct connections
to the branch circuit (that is, use of power strips).

or a universal RSU 129 1U 9.5-inch deep rack shelf kit (part #60-190-01), as shown below.
1. Remove the rubber feet (if installed) and mount the unit on the rack shelf, using two
screws in opposite (diagonal) corners.
2. Install blank panels or other units to the rack shelf, as required.
3. Insert the shelf into the rack, and secure the shelf to the rack using the supplied

2. If feet were previously installed on the bottom of the unit, remove them.
3. Hold the unit 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. Drill 3/32 inch (2 mm) diameter pilot holes, 1/4 inch (6.3 mm) deep in the mounting
surface at the marked screw locations.
5. Insert #8 wood screws into the four pilot holes. Tighten each screw into the mounting
surface until just less than 1/4 inch of the screw head protrudes.
6. Align the mounting screws with the slots in the brackets and place the unit against the
surface, with the screws through the bracket slots.
7. Slide the unit slightly forward or back, then tighten all four screws to secure the unit in
place.
