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
1T-SX-644 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
Connect the HDMI Video Sources to the inputs of the 1T-SX-644 HDMI v1.4 Fast
Switcher w/3D-ARC, connect its output to a HDMI Compliant monitor and lastly connect
the AC to DC Power Adapter. The drawings below show the locations of the inputs,
output, power switch and power connector.

4.1 Connecting the HDMI Inputs
You can connect any HDMI compliant device’s output to any of the HDMI inputs. Make
certain that the HDMI cable is securely plugged into the source device as well as the
HDMI Switcher. Always use a high quality cable, as short a length as possible, for best
results.
4.2 Connecting the HDMI Output
Using a high quality HDMI cable, connect the output of the HDMI Switcher to an HDMI
compliant display device. Use the shortest cable run possible.
4.3 Connecting Power
The unit 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 that there is no power switch. The
unit will power up as soon as you connect the AC Adapter to an appropriate AC source.
4.4 Optional Rack Mount Kit
The 1T-SX-644 HDMI v1.4 Fast Switcher w/3D-ARC can be mounted in a standard 19”
equipment rack. To mount the units, the optional RM-230 Rack Mount kit must be
purchased. Using this kit, either type HDMI switcher can be mounted in the rack. It is
also possible to mount one of each switcher in the rack using the dual rack mount
capability. It is not necessary to mount two of the same type of switchers.
5.0 OPERATING THE SWITCHER
The 1T-SX-644 HDMI v1.4 Fast Switcher w/3D-ARC may be operated via the Front
Panel controls, the IR remote control or via RS-232 protocols.
5.1 Operation via the Front Panel
Inputs are selected by pressing the appropriate input select button. An LED will light
adjacent to the selected input confirming your selection.
All other operations are accomplished via an On Screen Display (OSD) menu. The OSD
menu is accessible from either the front panel or from the included Infra-Red remote
control.
The OSD menu structure is displayed by pressing the Menu button on either the front
panel or the remote.
The menu structure is shown below.

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.
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.
