4.0 CONNECTINGTHE HARDWARE
The AVT-6544 has a single LED that indicates when power has been applied, an
Infrared remote control sensor located behind a square translucent window next to the
power on/off button, four sets of four buttons that allow signal selection for the four
outputs and signal selection indicator LEDs. The rear panel has the power connection,
four input connections and four output connections and an RJ-45 connector that is not
currently used on this product. Please take a moment to familiarize yourself with the
location of the various signal selection buttons, the input and output connectors and the
power input connector.
Note that you have four groups of outputs, each of which allows four possible input
selections. This technology is called a 4x4 matrix switcher because all four inputs and
all four outputs can be controlled independently without having an effect on one
another.
Note: Make certain you connect only the suppliedpower adaptor to the device as
serious damage can result by usingimproper voltages.

5.0 OPERATING THE UNIT
5.1 Connectthe Unit as follows:
1. Turn off power to each HDMI source device and to all HDMI destination devices
(such as Monitors).
2. Connect the output of each source device to the AVT-6544 4x4 Matrix switcher’s
inputs using high quality HDMI cables.
3. Connect the input of the destination devices to the output connectors of the AVT-
6544 using high quality HDMI cables.
4. Turn on power to the destination Devices.
5. Plug the DC Connector from the 9VDC Power Adapter provided into the
Amplifier.
6. Plug the Power Adapter into an AC Outlet and turn on the AVT-6544.
7. Turn on power to the source Devices.
Note: The AVT-6544uses Output 1 as the primary EDID source for all Inputs. If there is
no display connected to Output 1 the AVT-6544 will use a built in “compatibility” EDID.
When you press the power button, the red Power LED will illuminate on the AVT-6544 if
the unit is receiving 9 volts DC. The LEDsabove each of the selection buttons will
illuminate with a white light if there are valid HDMI signals present. If you have these
indications on the front panel of the AVT-6544, it means the switcher is ready for you to
make your routing selections.
5.2 Making Signal Routing Selections
The purpose of a matrix switcher is to allow the user to route input signals to different
destinations independent of one another.
The device is called a matrix because you can send one of four signals to a single
destination; send four different source signals to four different destinations or any
combination thereof.
For instance, you might wish to send the HDMI signal present on input number one to
all four destinations. By pressing the input select for HDMI source number one for all
four of the outputs, all four destinations will receive the HDMI source present on input
number one.
By the same token, you could select input source number one for output number one
and then select HDMI source two as the input signal on output two. Whatever is
connected to the switcher’s output number one would then receive the HDMI source
present on the switcher’s input number one but the device connected to switcher output
number two would receive the HDMI signal present on the switcher’s input number two.

6
Using this same approach, any of the four HDMI inputs can be sent to any of the four
outputs present on the AVT-6544.
When you make a selection as explained above, the white LED above the appropriate
input button for each output group will turn green. This means you can tell at a glance
which input each of the four outputs is receiving at the moment. By noting which of the
input LEDs is white, you can also tell if pressing the input button will result is sending
that input’s HDMI signal to the output for the desired output.
Note that once the AVT-6544 is receiving power, you can change the input cables to
different HDMI sources and the AVT-6544 will recognize that you have plugged in a
new HDMI source and light the white LED above the appropriate input (if there is a valid
HDMI signal present). This is called “Hot Plug” sensing and if the LED is white, you can
select the HDMI source is a valid HDMI format even though you didnot power down the
unit and the sources to reinitialize the unit.
5.3 Using the Infrared Remote Control
6.0 TROUBLESHOOTING
A problem with the AVT-6544 4x4 HDMI Matrix Switcher is rare. Most of the time,
problems are caused by the use of low grade cable, too long of a cable run, bad
connectors on the cable or occasionally by damaged cables. Bad grounds or use of
different AC power sources for the AVT-6544, Signal Source and/or Display Device(s)
may also cause problems due to ground loops. If the unit should free –something that
can happen to any electronic device due to momentary voltage surges or a millisecond
loss of power, power down all sources, destination devices and the AVT-6544 and re-
power them using the procedure described in section 5.1.
After trying the above suggestions should the problem still persist, contact your dealer
for additional suggestions before contacting AV Toolbox. Should the dealer’s technical
personnel be unable to assist you, contact AV Toolbox via the TV One support website:
http://tvone.crmdesk.com. Create a technical support request on the site and our
support team will respond within a short period oftime.
The Infrared Remote Control is organized using the
same logic as the front panel control buttons. Each
output has four dedicated input selection buttons. By
pressing an input section button, you can cause the
desired HDMI source to appear on the desired output.
Pressing the button on the top left causes the AVT-
6544 to enter the standby state and pressing the
button at the top right causes a reset command to be
generated.
