1.3 Getting the Best Results
There are many factors affecting the quality of results when switching HDMI type
signals. Some basic precautions will ensure the best possible performance from
your AVT-6441 HDMI v1.4 FAST Switcher with 3D / ARC.
Output display device – The quality of the output signal will depend
largely upon the type and quality of the HDMI display device used.
For instance, some video projectors just look better than others.
Distance between the switcher, the sources and the display – This
plays a major role in the final result. Long distances are possible, but
special measures should be taken in order to avoid cable losses.
These include using high quality cables. Line amplifiers may also be
necessary for the longest runs.
Input/Output connection cables – Low quality cables are susceptible
to interference. They degrade signal quality due to poor matching and
can cause elevated noise levels. Cables should be of the best quality.
Interference from nearby electrical devices – These can have an
adverse effect on signal quality. For example, an older computer
monitor often emits very high electromagnetic fields that can interfere
with the performance of video equipment in its proximity.

4.0 CONNECTING THE HARDWARE
The first step is to connect the HDMI Video Sources to the inputs of the AVT-
6441 HDMI v1.4 FAST Switcher with 3D / ARC. Next connect its output to a
HDMI Compliant monitor and lastly connect the AC to DC Power Adapter. The
drawings on the next page show the locations of the input, outputs and power
connector.
Connecting the Inputs to the AVT-6441
You can connect any HDMI compliant device’s output to any of the AVT-6441’s
inputs. Make certain that the HDMI cable is securely plugged into the source
device as well as the AVT-6441. Always use a high quality cable, as short a
length as possible, for best results.

4.1 Connecting the AVT-6441 to a Display
Using a high quality HDMI cable, connect the output of the AVT-6441 to an HDMI
compliant display device. Use the shortest cable run possible.
4.2 Connecting Power to the AVT-6441
The AVT-6441 HDMI v1.4 FAST Switcher with 3D / ARC is shipped with a Power
Adapter to convert 100~240VAC@50-60Hz to 5VDC. Connect the DC Output
Cable from the Power Adapter to the back of the unit and then plug the Power
Adapter into an AC Receptacle. Note: There is no power switch for the AVT-
6441 HDMI v1.4 FAST Switcherwith 3D / ARC. The unit is active as soon as you
plug the AC adapter into an AC Receptacle.
5.0 OPERATING THE AVT-6441
The AVT-6441 HDMI v1.4 FAST Switcher with 3D / ARC is operated via the
included Remote Control. LED displays on the unit indicate which input is active
and an OSD (On Screen Display guides the user through system set up
functions.
5.1 AVT 6441 Remote Control
Operation of The AVT-6441 HDMI v1.4 FAST Switcher
with 3D / ARC is achieved via an included Infrared
Remote Control. Note: When you unpack the AVT-
6441 HDMI v1.4 FAST Switcher with 3D / ARC, you
may have to remove an insulator from the battery
compartment of the Remote Control in order for the
remote to receive power. The battery compartment
slides out from the bottom of the unit.

Option Description
Audio Return On/Off
The audio return function requires some explanation as it is a new feature of
HDMI 1.4.
The Audio Return Channel in HDMI 1.4 enables a TV, via a single HDMI cable,
to send de-embedded audio data “upstream” to an A/V receiver or surround
sound audio controller, increasing user flexibility and eliminating the need for a
separate S/PDIF audio connection.

11
HDMI enabled Digital Television Displays have always been able to receive
multi-channel audio through an HDMI connection, and this is still a typical
situation, with the TV positioned “downstream” from content sources and any
connected audio equipment. However, if a user had a TV with a built-in tuner or
DVD player, and wanted to send content “upstream” from the TV back to the
audio system once it had been decoded, a separate connection had to be
installed from the display device back to the audio amplifier, typically an S/PDIF
cable.
An Audio Return Channel-enabled TV can either send or receive audio via HDMI,
upstream or downstream, depending on system set-up and user preferences
which means that limitations of the S/PDIF approach are minimized.
When Audio Return is set to “Off”, the standard rules of HDMI audio handling
apply as summarized in the following chart: Examination of the chart will show
that there are situations where you cannot always recover the decoded audio
from the display device using the S/PDIF approach due to bandwidth limitations
or due to the display device not being able to decode all audio formats.

Enabling Audio Return (turning it on via the OSD Menu), allows full support of
audio that has been de-embedded at the display device using the same HDMI
cable that sent the signal to the display device for the return audio path to the
audio distribution system. This is superior to using a separate S/PDIF coaxial
cable from the display device back to the audio distribution system, particularly
since there may be situations where the display device may not de-embed a
particular signal type.

12
In that case, audio that’s not decodable by the display device is de-embedded at
the AVT-6441 and passed to the audio distribution system via the Coaxial Cable
Output using short cables. Because of this capability, it doesn’t matter if the
display device is unable to de-embed the desired audio type due to hardware or
software limitations.
The one requirement however is the display device must be capable of Return
Audio capability so use of this functionality is dependent on the display device
being fully HDMI 1.4 compliant.

6.0 TROUBLESHOOTING
In the event of problems, first make certain that the input and output cables are of
the highest possible quality, are less than 30 feet long and are undamaged.
Next, make certain that the AVT-6441 HDMI v1.4 FAST Switcher with 3D / ARC
is receiving power.
If all is well in these areas, remember that HDMI devices communicate with one
another so the source devices and destination device must be fully HDMI
capable. In addition, HDCP encryption requires additional processing which is
also dependent on the equipment you have connected to the sources and
destination device. If you experience problems using the AVT-6441 HDMI v1.4
FAST Switcher with 3D / ARC, you should attempt to determine what is wrong by
attaching each of the source devices – one at a time – directly to the destination
device using the same cables you are using with the expanded system. This is a
way of determining if the problem is due to bad cables or a problem with the
other devices. If you are unable to obtain a signal using this simplified path,
suspect the cables, the source device(s) or the destination device.
After trying the above suggestions should the problem still persist, contact your
dealer for additional suggestions before contacting TV One. Should the dealer’s
technical personnel be unable to assist you, contact TV One via our support
website: http://tvone.crmdesk.com. Create a technical support request on the
site and our support team will respond within a short period of time.
