multiple HDMI enabled audio/video sources and distributes the signal  
to up to 2 (4x2 Matrix) or 4 (2x4) HDMI enabled displa ys. The matrix 
can be configured to send an y input to any HDMI displays, monitors,  
projectors or TV’ s.
Over-Current and Over-Voltage Protectio n
The circuit boards are equipped with both over-current and over -voltage 
protection and will automatically power down if encountered. The circuit\

The 4x2 matix features analog stereo outputs and a  TOSLINK fiber 
optical digital audio output. Only one output is functional at an y given 
time. The primary output is the T OSLINK output. Connect an audio 
output to y our audio receiv er. 
The audio output pro vides audio from source device used by Output 1. If  
Output 1 is switched to Input 3, the audio from Input 3 will be pro vided.

Audio Output
Setup
With the matrix power switch in the OFF position, connect an HDMI High 
Speed cable from the HDMI Output of the most commonly used audio/
video source to the HDMI Input 1 located on the rear of the matrix. 
Similarly , connect the remaining source devices to the HDMI Input  Ports 
on the matrix .
Tips: Use the shortest length HDMI cables possible in each point 
in the installation. Use only High Quality and High Speed HDMI 
cables.
Next, connect an HDMI cable to the HDMI Output  Port 1 on the rear of  
the matrix. Connect the other end to the HDMI Input P ort of the display 
device. Similarly , connect the remaining HDMI Output P orts from the 
matrix to the other displa ys.
The matrix has internal memory that stores the system 
information for faster switching. Please follow the steps in the 
order listed: T urn ON the displays and ensure they are awake (not in 
standby mode). Check the displa ys INPUT setting to ensure the correct  
HDMI port is activ e.
T urn on the source devices and ensure they are awake (not in standby  
mode). Connect the power adapter to the matrix. Plug the power 
adapter into a surge protected AC power outlet. T urn the matrix power 
switch to the ON position.
The matrix has a low power dr aw and is intended to be left on. If  
the matrix is turned off , start up the system as noted abo ve. If new 
hardw are is added, please perform a RESET .
To  RESET the matrix, turn off the display and source devices.  Power off 
the matrix and unplug the power adapter from the rear of the matrix.  
Wa it 20 minutes for the memory of the system configu ration inside of  
the matrix to be deleted.  Follow the setup instructions abo ve to correctly 
initiate the setup .  
						

							Infrared Control (IR)
The Ultra-IR Adapter Kit (optional) enables the user to control the source 
device from the location of the displ ay. The HDMI cable, at the display  
end, plugs into the IR Adapter . Next the adapter’s HDMI connector plugs 
into the display . The adapter has a port that accepts an optional IR  
receiver (IR -RX). When the IR -RX receives an IR signal from the remote 
control, it uses the HDMI cable’ s CEC line to send the signal to the switch.  
The switch has an IR port that accepts the optional IR tr ansmitter (IR-
TX). The IR -TX sends the signal to the source device. 
Note: As the Ultr a IR-Adapter uses the CEC channel of the HDMI cable,  
the CEC function cannot be used when using this device.  Turn off CEC or 
HDMI Link functionality in the source devices and displa ys.

Troubleshooting
A. One of the displ ay does not show a picture or output audi o.
Q.  Check the displays input setting to ensure it is set to receive a signa\
l  
from the connected HDMI port .
Q.  One or more of the connected displays will not display a picture while  
one or more of the displa ys do display a picture:  
A1. T urn off the power to the matrix, source and displa ys. Wait 1 minute. 
T urn the source on. T urn the displays on. T urn the matrix on.
A2. The HDMI cables on the non-functonal displa y/s cannot support 
their long length.  Use only high-quality High Speed HDMI cables. K eep 
the cable length as short as possible. T est by locating the non-working 
display close to the matrix. Use a short HDMI cable to connect the matri\
x 
to the TV . A working TV using a short HDMI cable indicates an issue with  
the HDMI cable. Ultr

...troubleshooting continued
Q.  Get the message “This protocol is not supported” or other error 
message.  
A. See answer A1 abo ve and repeat the steps outlined .
Q.  The matrix is not down sampling the video and some of the TV’ s are 
not displaying a picture.  
A1. Go into the TV’ s setup and configure the resolution to match all the  
connected TV’ s. The TV’s should share the same resolution. 
A2. In the source devices menu options set the source device to output a\
 
resolution that matches all the connected displa ys.
Q.  My TV ’s resolution are not optimized.
A. The matrix will query the displa ys and provide the highest common 
video resolution amongst them. Example: Using a 1080p source, if 3 
of the displays support a maximum resolution of 1080p and 1 displ ay 
supports a maximim resolution of 720p , all 4 display will operate at a 
resolution of 720p .  If the 720p TV in the example is then turned of f, 
the other 3 displa ys can then operate in 1080p resolution. T urn Off then 
turn On the matrix to refresh the configur ation. The three 1080p TV’s will 
refresh (flick er) then each will displ ay a 1080p resolution picture.

LED indicator lights
On initial power on, all LED lights on the matrix should come on solid  
blue. All the numerical LED displa ys will momentarily read ‘0’ and 
then change to ‘1 ’. If less than the maximum number of Displa ys 
are connected to the matrix (not all the outputs are used) the 
numerical indicator will indicate ‘0’ for that output and there wi\
ll be no 
corresponding  HDMI OUT blue LED for the unused output. Blue lights 
will only appear for devices connected. An y unused HDMI Input ports will 
also have its  HDMI IN blue LED unlit.
Operation
Manual Control : Yo u can oper ate HDMI source switching manually by  
using the buttons labeled ‘Out” located on the front panel. Press \
the 
button that corresponds to the output that y ou want to change the HDMI 
source on and toggle through until the desired HDMI input source video 
is being displayed. A numerical LED indicates which HDMI source input is\
  
being shown on each output (HD TV).
Remote Control:  Included with the Matrix is a R emote Control. The 
remote control can control the matrix  by pointing it at the front of the 
matrix, targeting the integr ated IR receiver labeled IR. IR uses line-of -
sight between the remote control (or IR -TX) and the receiver . The angle 
which the remote will work is at about a 15° degree angle in either  
direction to the recei ver. If the receiver is postioned such that there 
is not line-of -sight, the port labeled “IR Extender” accepts an optional  
IR R eceive r. This receiver enables line-of -sight if the matrix is out of 
position.
