The Extron P/2 DA2xi and the P/2 DA2xi MT are distribution
amplifiers that accept video input from a VGA, XGA, or UXGA
compatible PC and distribute the signal to separately buffered
outputs. Each output can be extended with Extron VGA MHR
cables from 6' to 250' in length. The MT model also has audio
input and output.
Features
• Power/Signal LED — Green LED = power + signal.
Amber LED = power but no signal. Off = no power.
• Gain/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 (either model) with the supplied chain (attached to the
right standoff nut of the input VGA connector) to prevent the
cable from becoming lost or misplaced.

Installation
The P/2 DA2xi and P/2 DA2xi MT can be mounted on a rack
shelf, under a desk or tabletop, or on a projector bracket.
Use 2 mounting holes on
opposite corners.

FCC Class A Notice
Note: This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful
interference, in which case the user will be required to correct the interference at his
own expense.
Note: This unit was tested with shielded cables on the peripheral devices. Shielded
cables must be used with the unit to ensure compliance.

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 unit 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 unit in place.

CAUTION
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.
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.
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.

2-bank DIP switches — These switches affect only the
video output (

), not the “monitor” output (3). The
Gain/Peak DIP switch should be on (up) when output
cable is over 100' (30.5 m). The Out Imp DIP switch
changes output impedance. If all connections and
operations are correct, yet the output device has no picture,
switch to the other position.

Video output connector — Connect the video output
device (projector, display panel, or monitor) to this
connector.
