FCC Class A Notice  
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. Operation is subject to the following two conditions: (1) this  
device may not cause harmful interference, and (2) this device must accept any interference received,  
including interference that may cause undesired operation. The Class A 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.

Description  
The P/2 DA4xi and P/2 DA6xi VGA-UXGA are high  
performance distribution amplifiers featuring one input, four  
outputs and one input, six outputs, respectively. Both P/2 DA  
units accept a VGA-UXGA video signal from a computer and  
distribute the signal to individually buffered outputs and one  
buffered loop-through. Each output is extendable up to 250'  
(76 m) with Extron’s VGA cables.  
Examples of typical installations are shown in the diagrams on  
the following pages.  
Features  
Bandwidth — 300 MHz (-3dB) RGB video bandwidth, fully  
loaded  
Video Gain switch — Selectable video gain of 0.7 V or  
1 V (when the input signal is 0.7 V p-p) to compensate for  
long cable runs  
Power LEDs — Located on both front and back panels  
Versatile mounting options — A metal enclosure and a  
wide variety of mounting options  
ID bits pass through — Ensures the signal from the source  
matches the resolution and refresh rate of the local monitor.  
Installation  
The P/2 DA4xi and P/2 DA6xi can be mounted on a rack shelf,  
under a desk, or through a desk.  
Rack mounting  
UL guidelines for rack mounting  
The following Underwriters Laboratories (UL) guidelines are  
relevant to the safe installation of these products 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. Reduced air flow — Install the equipment in the rack so that  
the equipment gets adequate air flow for safe operation.

P/2 DA4xi and P/2 DA6xi, cont’d  
3. Mechanical loading — Mount the equipment in the rack so  
that uneven mechanical loading does not create a hazardous  
condition.  
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. 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 procedure  
The distribution amplifier can be mounted on any of the  
following optional rack shelves:  
RSU 126 6" deep 1U Rack Shelf Kit (part #60-190-10)  
RSB 126 6" deep Basic Rack Shelf (part #60-604-10)  
RSU 129 9.5" deep rack shelf (part #60-190-01) or  
RSB 129 9.5" deep Basic Rack Shelf (part #60-604-01)  
To install and set up the P/2 DA4xi or P/2 DA6xi on a rack,  
follow the steps on the next page and see the diagram below:

1.  
2.  
If rubber feet were installed on the unit, remove them.  
Attach the mounting brackets to the unit with the provided  
machine screws, as shown below.  
3.  
4.  
5.  
6.  
7.  
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.  
Drill 3/32" (2 mm) diameter pilot holes, 1/4" (6.3 mm)  
deep in 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" of the screw head protrudes.  
Align the mounting screws with the slots in the brackets  
and place the unit against the surface, with the screws  
through the bracket slots.  
Slide the unit slightly forward or back, then tighten all four  
screws to secure the unit in place.

Operation  
After the distribution amplifier and its connected devices are  
powered up, the system is fully operational. If any problems  
occur, verify that the cables are properly routed and connected.  
Signal input and output connections  
All connections, including power, input, and output, are located  
on the rear panel of the P/2 DA4xi and P/2 DA6xi.  
To make input and output connections to other devices, do the  
following:  
1.  
2.  
Turn off the PC and local monitor.  
Connect the input cable from the P/2 distribution  
amplifier (DA) to the computer’s VGA-UXGA output.  
If you wish to send RGBHV, RGBS, RGBsB, RsGsBs,  
component video, S-video, or composite video signals, use  
a standard SY breakout cable to make the connection. See  
the illustrations below.

Video Gain  
The Video Gain switch is located on the rear panel with a default  
setting of 0.7 V (down). Set the switch to 1 V when long cable  
runs affect the picture quality. This boosts the signal level to  
compensate for degradation due to cable length.  
Signal Compatibility  
Signal compatibility is affected by voltage. When the Video  
Gain switch is set to  
0.7 V (default) — the P/2 DA can pass all signal types  
(VGA-UXGA, RGBHV, RGBS, RGBsB, RsGsBs, component  
video, S-video and composite video).  
1 V — the P/2 DA can pass only the RGBHV and RGBS  
video types.
