Model 1398E

Introduction
Thanks for purchasing a 4K distribution amplier from Audio Authority®. The
1398E with resolution tracking are designed to distribute 4K video signals to
multiple displays in a retail environment. The latest chipsets allow 4K video
signals to be scaled automatically to match each display’s optimal resolution
and video format. With this capability it is no longer necessary to divide TVs
on display into separate distribution systems, according to their resolution.
Link multiple distribution ampliers to create a hub-and-spoke layout for large
distribution systems.
Features
● Two HDMI inputs, eight HDMI outputs
● Port-by-port EDID management 4K to 1080p down-scaling and color space
conversion (4:4:4 to 4:2:0), independent HDCP management engine for each
output ensures stable performance
● Special “Group Mode” allows the 1398E to function as two independent 1×4
splitters in a single device
● Supports 4K resolutions up to 3840x2160@23/24/25/29/30/50/59/60Hz
and 4096x2160@23/24/25/29/30/50/59/60Hz
● HDCP 2.2 compliant
● Clock Speed: 300MHz~600MHz
● Video bandwidth: 18Gbps
● Support for eight internal EDIDs, eight external EDIDs copied from connected
devices, and two user provided EDIDs
● Supports CEC “active source” commands to periodically reset the input
selection on CEC-compatible connected displays
● Controllable via front-panel buttons, with OSD, and RS-232
● Supports all bitstream audio formats such as LPCM 7.1 Dolby Digital and DTS
● Mini-USB rmware update for expanding compatibility
Checking Package Contents
Before attempting to use this device, please check the packaging and make
certain the following items are contained in the shipping carton:

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.
● Port-by-Port EDID management - 4K to 1080p down-scaling and color space
conversion (4:4:4 to 4:2:0), independent HDCP management engine for each
output ensures stable performance so make sure port 1 is connected to a TV
with the highest resolution capability. Enable HDR on the high resolution outputs
using the OSD or RS-232.
● Source resolution and video/sound quality - Sources, such as satellite
receivers or cable boxes can output at low resolutions or deliver compressed
video material that may yield poor results. Consider the source when planning
and troubleshooting your system.
● Distance between the DA source and the displays - Use the shortest
cables possible, but premium certied high speed cables and advanced
HDMI extenders 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 certied high speed cables designed to handle 4K resolutions and 3D;
low quality cables are susceptible to interference. Always use good strain relief
methods to prevent cables from becoming loose over time.
● Interference from nearby electrical devices - RF emission 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.

● 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 with every feature
and format.
● Since HDMI connectors can sometimes become loose, 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.

Wiring the System
● Switch off all devices, including monitors.
● Connect a premium certied high speed cable from the HDMI source to the
input(s) of the 1398E. Cable lengths should be kept as short as possible.
● Connect the outputs of the 1398E to displays or other devices.
● Make certain that the HDMI cables are securely plugged into the source and
display devices as well as the 1398E. Always use premium certied high speed
cables, and the shortest length possible, for best results.
● Connect the power adapter to the AC source and then to the 1398E.
● The 1398E begins to function as soon as the AC adapter is connected to the
1398E and AC power. There is no power switch.
● Turn on the HDMI source and HDMI destination devices and observe the source
signal on the inputs of all of the destination devices.
Note: Proper operation of HDMI distribution ampliers depends on the use
of premium certied high speed HDMI cables with low loss, high bandwidth
signal handling capabilities.
Switch Settings
The 1398E can be controlled by using the front panel switches or when viewed

Troubleshooting
● For 4K resolution, use premium certied high speed HDMI cables and a
high speed HDMI Extender (if needed) that supports 4K. Make certain that
the input cable is as short as possible. HDMI cable design and quality are
extremely important in long cable runs where capacitance can severely impact
performance.
● Make certain that the distribution amplier’s power LED is illuminated and
not ickering on and off. Intermittent operation generally means a problem with
the DC power adapter or low AC voltage being supplied to the DC adapter’s
input.
● Due to a chipset limitation, 4K sources using the 4:2:2 color space may display
with incorrect colors when scaled to 1080p. If this occurs, partitioning the 1398E
into two 1x4 switchers may provide a solution in this case.
