Introduction
The Ultr aAV HDMI Distribution Amplifier (Splitter) accepts a signal from 
a single HDMI enabled audio/video source and splits the single input  
into 4 (1x4 Splitter) or into 8 (1x8 Splitter) HDMI outputs. The aud\
io/
video signal is mirrored on up to 4 (1x4 Splitter) or 8 (1x8 Splitter\
) 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\
 
boards will restore automatically once the ex cessive current or voltage 
has passed.

Cascading
The HDMI splitter can be cascaded (l ayered) to expand the number of  
supported displays.  
K078C -006B (1x4 Splitter) - Supports up to 3 la yers. 
K078C -007B (1x8 Splitter) - F eatures a Silicon Image chipset supporting 
up to 6 layers .
To  create a 2 layer cascade, two same distribution amplifiers must be  
used. R un an HDMI cable from an output on unit #1 to the input of unit 
#2. A 2 layer cascade of the 1x4 splitter will support up to 7 outputs. \
A 2 
layer 1x8 splitter cascade will support up to 15 outputs.
Setup
With the splitter power switch in the OFF position, connect an HDMI High 
Speed cable from the HDMI Output on the audio/video source to the 
HDMI Input 1 on the back of the splitte r. 
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 P ort 1 on the splitter 
and then connect the other end to an HDMI Input P ort on the display 
device. Similarl y, using HDMI cables, connect the remaining HDMI Output 
Po rts on the rear of the splitter to the HDMI Input ports of the other 
displays.
Connect the power adapter to the splitte r. Plug the power adapter into a 
surge protected AC power outlet. T urn ON the video source, and turn ON 
the displays. T urn the splitter’ s power switch to the ON position . 
						

							Infrared Control (IR)
The area on the front panel labeled  IR or IR Extender is the IR 
Tr ansmitter (I R-TX) port. 
Using the Ultr a-IR Adapter Kit (optional) enables the control of the source 
device from the location of the displ ay. Plug the HDMI cable into the IR  
Adapter at the displ ay end. Next plug the IR Adapter ’s HDMI connector 
into the display . The IR Adapter has a port that accepts an optional IR  
Re ceiver (I R-RX). When the IR -RX receives an IR signal from the source 
devices remote control, it uses the HDMI cable’ s CEC line to send the 
signal to the splitte r. Plug the optional IR -TX into the IR port on the front 
panel of the splitte r. Po int the end of the IR -TX at the source device. 
The signal is tr ansmitted through the IR -TX sending the IR 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. 
The illustra tion below shows the optional Ultr a-IR Adapter Kit controlling 
the source device on a 1x4 splitte r. The 1x8 splitter is setup in a similiar 
manner . Note: Due to specific pin requirements, only use Accell Ultr a-IR 
tr ansmitters or receivers.

Troubleshooting
Q.  One of the display does not show a picture or output audio.
A. Check the displa ys input setting to ensure it is set to recei ve a signal  
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. Press the  RESET button on the front of the splitter to reset it. 
Alternatively turn off the power to the splitte r, source and displa ys. Wait 
60 seconds. T urn the source on. T urn the displays on.T urn the splitter 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 splitte r. Use a short HDMI cable to connect the 
splitter to the TV . A working TV using a short HDMI cable indicates an 
issue with the HDMI cable.
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 splitter is not down sampling the video and some of the TV ’s are 
not displaying a picture. Ultr

troubleshooting continued...
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 splitter 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 displays can then oper ate in 1080p resolution. Press the  RESET 
button on the front panel of the splitter to refresh the configur ation. The 
three 1080p TV’ s will refresh (flick er) then each will displ ay a 1080p 
resolution picture.
