3.0 GETTING THE BEST RESULTS
Many factors inuence the quality and reliability of HDMI signal distribution
installations. The following are the main factors to consider, and basic
precautions that will ensure the best possible performance.
• Resolution tracking. Set up the source to output the best resolution that all
TVs are capable of displaying. Follow the instructions in 4.0 to insure that all
TVs connected to the DA receive video signal. If the TVs have a wide range of
resolution capabilities, the highest resolution sets may not be shown to their
best advantage.
• Source resolution and video/sound quality. Sources, such as satellite
receivers or cable boxes can output at low resolutions or deliver extremely
compressed video material that may yield poor results. Consider the source
when planning and troubleshooting your system.
• Output display devices. The quality of the output signal depends largely
upon the type and quality of the HDMI display devices used.
• Distance between the DA sources and the display. Long distances are
possible, but premium quality cables and advanced HDMI extenders with DDC
correction may be necessary for the longest runs.
• Connection cables. HDMI cable design and quality are extremely important
in long cable runs where capacitance can severely degrade performance. Use
premium cables; low quality cables are susceptible to interference. Always use
locking cables or good strain relief methods to prevent cables from becoming
loose over time.
• Interference from nearby electrical devices can have an adverse effect
on signal quality. For example, older computer monitors often emit very high
electromagnetic elds that can interfere with the performance of nearby video
equipment.
4.0 PLANNING A DISTRIBUTION SYSTEM
• Each display should be tested with the source(s) being used to ensure basic
compatibility before connecting them to a distribution amp and/or switcher. Not
all HDMI components and displays are compatible.
• Since all of the displays will be receiving the same video signal resolution
and format (e.g. 1080p@60Hz) from the source, make sure the source is set
up to output the highest resolution that all of the displays can accept. For
instance, if one of the displays connected to the distribution system can only
accept a maximum input resolution of 720p, all of the displays will receive

Refresh Rate

only 720p video signals. You may consider creating two or three separate
distribution systems with different sources and different output resolutions so
that you can adequately demonstrate the highest resolution HDTV sets.
• HDMI cable lengths of up to 100 ft. between ampliers may be possible, when
premium cables are utilized. Use of high resolutions, refresh rate, or deep
color may limit maximum cable run length.
• Since HDMI connectors can sometimes become loose, use locking HDMI
cables or mount the switcher or distribution amplier to a at surface and add
strain relief tie-downs a few inches away from every HDMI cable connector.
4.1 Large HDMI Distribution Systems
If you plan to install a very large HDMI signal distribution network, you should be
aware of system limitations related to content protection. Audio Authority can help
you design a distribution system that suits your needs and is easy to install and
operate.
• Each system is limited to 128 Rx “nodes” including the rst Rx node.
• Every device with an Rx chip counts as one node, including TVs, distribution
amps, and switchers.
• The number of “layers” is limited to seven. That means the number of
switchers and/or distribution amps between a source and any TV must be six
or fewer. For this reason, a “hub and spoke” system architecture may be more
appropriate than a “daisy chained” architecture.
• A distribution system feeding the highest number of displays allowable using
two, four, and eight output distribution amps has a capacity of 108 TVs. The
distribution ampliers add up to 17 Rx nodes, and the source is one node, so
the total number of downstream nodes in this system is 127.
4.2 About 3D Content Distribution
• When the input signal contains 3D data all connected displays must support
3D content in order to display an image.
• Distributing 3D content also implies that all viewers have the 3D glasses
available for the appropriate TV. If this is not the case, 3D content may not be
a good choice for general signal distribution.
5.0 INSTALLATION
Study the front and rear panel drawings and become familiar with the controls,
signal input, outputs and power input.
5.1 Wiring the System
• Connect an HDMI approved cable from the HDMI source to the input of the
1398B. Cable lengths should be kept as short as possible.
• Connect the outputs of the 1398B to their displays or other devices.
• Connect the power adapter to the AC source and then to the 1398B.

7
• Make certain that the HDMI cables are securely plugged into the source and
display devices as well as the 1398B. Always use high quality cables, and the
shortest length possible, for best results.
• Turn on the HDMI source and HDMI destination devices and observe the
source signal on the inputs of all of the destination devices. The 1398B front
panel LED lights up, indicating 2D or 3D sync.
• The unit begins to function as soon as the AC adapter is connected to the unit
and AC power. There is no power switch.• 2D/3D LIGHT: This LED turns red
when the input signal is not 3D. If the input signal is 3D the LED changes to
orange.
Note: Proper operation of HDMI distribution ampliers depends on the use
of high quality HDMI cables with low loss, high bandwidth signal handling
capabilities. The distance specication cannot be guaranteed unless cables used
throughout the system meet these high standards.

5.2 Operation
1. CEC AUTO-RESET: Triggers a periodic reset via the Consumer Electronics
Control circuit. Use this feature when one display may send a signal to other
displays changing their settings. When CEC AUTO-RESET is on, the 1398B
switches each display to its HDMI input #1 every 8-10 minutes. It does not
work on displays that do not support CEC, or if CEC is turned off.
2. EDID* SWITCH: Leave on TV setting, which supports 3D content, unless
some TVs do not sync with the source. In TV mode the 1398B reads the EDID
on output 1 and records it, then allows the source to send matching HDMI
signals to the other seven HDMI outputs. In STD mode the 1398B uses its
built-in EDID, which is set at 1080p@60/12bits for video and LPCM 2Ch for
audio. Use this setting when there is a problem getting the source to send a
signal to all of the connected displays.

6.0 TROUBLESHOOTING
• For 1080p resolution, rst make certain that the input cable is as short
as possible and none of the output cables are more than 30 meters long.
HDMI cable design and quality are extremely important in long cable runs
where capacitance can severely effect performance. Our 1391A Extender/
DDC Corrector may be a necessary accessory to use in extreme length
applications.
• Make certain that the distribution amplier is receiving power by looking at the
power LED. It should be illuminated and not ickering on and off. Intermittent
operation generally means a problem with the DC power adapter or low AC
voltage being applied to the DC adapter’s input.
• If some lower resolution TVs do not display a picture, make sure the source
is producing a resolution low enough that all TVs can accept it. Try 720p, or
1080i and, if possible, manually set your source to the desired resolution. In
some cases, hot-plugging a high resolution display may actually reset the
source to a resolution that cannot be accepted by some other TVs. You may
need to separate your distribution system into separate 1080p, and 1080i
systems with a source for each system.
• If some displays are not receiving video signal, or lose signal, check to
see if they are on the wrong input. One display may be sending out a CEC
command, changing the inputs on other displays. Turn on the 1398B CEC
AUTO-RESET (see page 7), or turn the displays’ CEC feature off.
• If you still experience problems using the distribution amplier, troubleshoot by
rst attaching the source device directly to each of the destination devices in
turn 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 simplied path,
suspect the cables, the source device or the destination device.
• Remember that HDMI devices communicate with one another so the source
device and all destination devices must be fully HDMI capable. In addition,
HDCP encryption requires processing dependent on the equipment you have
connected to both the source and destination devices.
If a problem still persists after trying the above suggestions, contact the Audio
Authority Technical Service department via email:
