Introduction
About This Manual
This manual contains information about the Extron P/2 DA8,
P/2 DA8 A, P/2 DA12 and P/2 DA12 A distribution amplifiers
with instructions on how to mount, install, and operate these
units.
Unless otherwise specified, references to "the distribution
amplifier" in this manual relate to the features or operation of all
four of these models.
Description of P/2 DA8 and P/2 DA12 Series
The Extron P/2 DA8 and P/2 DA12 series are a family of high
performance VGA-QXGA distribution amplifiers, available with
or without audio.
All models accept a single video input signal, which may be
RGBHV, RGBS, RGsB, RsGsBs, HDTV component (tri-level and
bi-level sync), S-video, or composite video. They are compatible
with resolutions from VGA (640 x 480) to QXGA (2048 x 1536).
The signal is distributed to eight (P/2 DA8 series) or twelve
(P/2 DA12 series) outputs, without modifying the signal: the
output video signal format follows the input format.
An XGA signal can be extended up to 150' over Extron mini high
resolution (MHR) cable.
The audio versions (P/2 DA8 A and P/2 DA12 A) also accept
a single, unbalanced audio signal and distribute it to eight or
twelve, balanced or unbalanced, audio outputs.

Installation and Operation
Installation Overview
The distribution amplifiers can be mounted on tabletops, in
racks and under furniture. Through-desk mounting is not
recommended for these products. To install these units, follow
these steps:
1.
Turn off all electrical equipment. Make sure that the input
sources, the distribution amplifier, and the output displays
are all turned off, disconnected from their power sources,
and connecting cables have been removed.
2.
Mount the unit (see "Mounting the Distribution
Amplifier" below).
3.
4.
Connect the Cables (see "Operation" on pages 2-8 to 2-12).
Plug in the power supply and turn on the display devices
and input devices.
Mounting the Distribution Amplifier
The 1 U, full rack size of these distribution amplifiers allows
them to be mounted on a tabletop, on racks, or under furniture.
Tabletop placement
Attach the four included rubber feet to the bottom of the unit
and place it in any convenient location.
Rack Mounting
UL requirements for rack mounting
The following Underwriters Laboratories (UL) concerns are
relevant to the safe installation of these distribution amplifiers in
a rack:
1.
Elevated operating ambient temperature — If the unit
is 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 equipment in an environment compatible with
the maximum ambient temperature (Tma: +122 °F, +50 ° C)
specified by Extron.
2.
3.
4.
Reduced air flow — Install the equipment in the rack
so that the equipment gets adequate air flow for safe
operation.
Mechanical loading — Mount the equipment in the rack
so that uneven mechanical loading does not create a
hazardous condition.
Circuit overloading — Connect the equipment to
the supply circuit and consider the effect that circuit
P/2 DA8 and P/2 DA12 • Installation and Operation

Download from Www.Somanuals.com. All Manuals Search And Download.
overloading might have on overcurrent protection and
supply wiring. Give appropriate consideration to the
equipment nameplate ratings 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 (such as the use of power
strips).
Rack mounting procedures
The units can be rack mounted, using the MBD 149 mounting kit
(part #70-077-03) provided with the unit.
1. Remove rubber feet if these have been installed on the
bottom of the unit.
2. Secure one bracket to each side of the distribution amplifier
with the provided bracket mounting screws (four #8 screws
for each bracket — see figure 1 below).

Each output is assigned to a pin on the captive
screw connector. To mute any output, short
its pin to the ground pin ( ). Multiple outputs
can be shorted at the same time. To mute all outputs at once,
short pin A (all) to the ground pin.
The P/2 DA8 A model uses two 3.5 mm, 5-pole, captive screw
connectors. The P/2 DA12 A model (shown above) uses two
3.5 mm 4-pole connectors and two 3.5 mm 3-pole connectors.
For connections to captive screw receptacles, the length of the
exposed wires is critical.
The ideal length of stripped wire is 3/16” (5 mm):
N
•
•
If the stripped section of wire is longer than 3/16”,
the exposed wires may touch, causing a short circuit
between them.
If the stripped section of wire is shorter than 3/16”,
the wires can be easily pulled out even if tightly
fastened by the captive screws.
Do not tin the wires. Tinned wire does not hold its
shape and can become loose over time.

Troubleshooting
After input and display devices are connected to the distribution
amplifier and all units are powered up, the system is fully
operational. If any problems occur, ensure that the cables are
properly routed and connected. Some common problems and
diagnostic checks are shown below:
If the LED light on the front panel is not on, the distribution
amplifier is not receiving power. Ensure that the electric outlet
is functional and that the power cord is correctly connected (see
page 2-7).
If there is no image on the display device, check that there is
an input signal. If the LED light is amber, the power is on but
the distribution amplifier is not receiving an input signal. Verify
that the cables are correctly connected from the input device and
that the input device is switched on (see pages 2-9 and 2-10).
If the front LED is green but there is still no output signal:
• Check that the cables to the output device are connected
correctly (see pages 2-9 and 2-10).
• Make sure that the output for that channel has not been
muted (see page 2-11).
• Change the sync impedance of the output to 75 ohms on the
front panel (see page 2-8).
If the source is a laptop computer, which is providing an
unstable output image, ensure sync impedance switch number
1 (input sync) is in the ON position (see page 2-8).
If output 1 supports an image but other display devices do not,
ensure that the resolution capabilities of the display device on
output 1 does not exceed the resolution capabilities of output
devices on the other channels. For optimal performance, all
display devices should have similar resolution capabilities (see
page 2-9).
