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  
2-2  
 
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).

4.  
5.  
Hold the unit, with the brackets attached, against the  
underside of the table or other furniture. Mark the location  
of the holes in the bracket on the mounting surface.  
Drill four pilot holes, each 3/32" (2 mm) in diameter by  
1/4" deep (6.3 mm) deep, into the mounting surface at the  
marked screw locations.  
Insert #8 wood screws into the four pilot holes. Tighten  
each screw into the mounting surface until just less than  
1/4" (6.3 mm) of the screw head protrudes.  
6.  
7.  
Guide the slots in the mounting brackets over the  
protruding screw heads.  
Slide the unit forward or backward by 3/8" (4.7 mm) so  
that the brackets are supported by the screws. Tighten all  
four screws to secure the unit in place.

Video Input and Output Connections  
All models are able to accept RGBHV, RGBS, RGsB, RsGsBs,  
YUV (tri-level and bi-level sync), S-video and composite video,  
and resolutions from VGA (640 x 480) to QXGA (2048 x 1536).  
The signal is distributed without modification: the output  
format follows the input format.  
To make input and output connections with other devices,  
follow these instructions:  
1.  
2.  
3.  
Turn off the power to the distribution amplifier and the  
video source.  
Connect the video source to the 15-pin female HD input  
socket on the rear panel of the distribution amplifier.  
Connect the display devices to the 15-pin female HD  
output sockets on the rear panel of the distribution  
amplifier.  
ID bits on pins 4, 11, 12, and 15 are routed to Output 1.  
N
N
For optimal performance, all display devices should have  
similar resolution capabilities.  
For sources and displays that require different  
connectors, use an HD adapter cable, such as the Extron  
SY BNCM series (#26-533-xx; see the figure below, at  
left). The BNC connectors used for different signal types  
are shown in the figure below, at right.

The audio outputs can be balanced or unbalanced depending  
on the wiring (see figure 2-8 on the next page). The length of  
exposed wires in the captive screw connector is critical (see the  
note and caution on the next page).  
Balanced output wiring produces a +6 dB gain.  
Unbalanced output wiring produces 0 dB gain.

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).
