Step 1 — Power down and mount
Turn off or disconnect all equipment from power sources and mount the P/2 DA2xi MT as
needed. Refer to the user’s guide for mounting details.
When lit green, Power/Signal indicator LED (a) indicates that the distribution amplifier is
receiving both power and a computer signal. When it is lit amber, it indicates that the
P/2 DA2xi MT is receiving power but no computer signal.
Step 2 — Connect inputs
• Connect a 3.5 mm, mini audio plug cable from the sound
card of the PC to the audio input connector (b). Wire the
audio plug as shown on the right.
• Connect the VGA-QXGA output of the PC to the 15-pin HD
video input connector (c).
• Connect a local monitor to the 15-pin HD monitor input connector (d).
NA local monitor cable assembly (i) can be chained to the unit to prevent it from being
misplaced.
Step 3 — Connect outputs
• Connect the video output device (projector, display panel, or monitor) to the 15-pin HD
video output connector (g).
• Connect a 3.5 mm, 5-pole, captive screw audio connector to the 5-pin audio output
connector (h). Connect the other end of the audio cable to an audio output device.
See the audio wiring diagrams on the other side.

CConnect the sleeve to ground (Gnd). Connecting the sleeve to a negative (-) terminal
will damage the audio output circuits.
Step 4 — Power up
Plug the external 12 V power supply into this 2-pole captive screw connector. The included
power supply is shipped with a plug installed on the DC output cord. If the DC output cord
needs to be cut to a different length, see the following figure and notes for reinstalling the DC
output plug.

CWhen 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.
NDo 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.
WThe 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.
Step 5 — Set DIP switches
These switches affect only the video output (g), not the “monitor” output (d).
The Gain/Peak DIP switch should be on (up) when the output 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 has no picture, switch to the other position.
