Introduction
Thanks for purchasing the Model 1398D 4K Ultra HD distribution amplier from
Audio Authority®. The 1398D is designed to split a 4K HDMI®signal from
one source to a wide spectrum of HDMI display brands, as in a retail demo
environment. It is the ideal solution for merchandising 4K displays using
the latest content at the highest resolutions, and refresh rates including
2160p@60Hz. Display-source compatibility is enhanced by the 1398D’s multiple
EDID options. Link multiple 1398Ds or create a hub-and-spoke layout for large
distribution systems.
Features
● Supports resolutions up to 4096x2160@24/25/30/50/60Hz and
3840x2160@24/25/30/50/60Hz
● HDCP 2.2 and 1.4 compliant
● Video bandwidth: 18Gbps
● Wide frequency range: 25MHz~600MHz
● Supports default EDID and learns EDID from displays
● Mini-USB rmware update for expanding compatibility
● Supports all bitstream audio formats including Dolby and DTS
● Compact footprint with outputs on two sides to reduce sharp cable bends
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:
● 1398D distribution amplier
● 5VDC power adapter
● User manual

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.
● Source Switching - If the source device will be switched often during operation,
as in the case of an HDMI switch connected at the head end of the distribution
system, use the SYS-RST switch. This setting prevents the 1398D from
interrupting video and audio transmission to re-learn EDID settings each time the
source is switched, or a TV is hot-plugged to the distribution system.
● Resolution tracking - Set the source to output the best resolution that all
TVs are capable of displaying. Utilize the following instructions to ensure 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 video image depends upon the
type and quality of the HDMI display devices used. The device with the lowest
resolution will be the reference standard for the rest of the HDMI displays
connected to the DA.
● Distance between the DA source and the displays -Long distances are
possible, but quality 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 High Speed Certied HDMI 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 - This 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.

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 from the source, make sure all the displays connected to the 1398D
can accept 2160p resolutions. If a display is limited to 1080p, for example,
either it will not display any image, or the source will reduce its output to
all displays to 1080p, depending on the 1398D settings. 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.
● 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 High Speed Certied HDMI cable from the HDMI source
to the input of the 1398D. Cable lengths should be kept as short as possible.
● Connect the outputs of the 1398D to displays or other devices.
● Make certain that the HDMI cables are securely plugged into the source and
display devices as well as the 1398D. Always use high speed cables, and the
shortest length possible, for best results.
● Connect the power adapter to the AC source and then to the 1398D.
● The unit begins to function as soon as the AC adapter is connected to the unit
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 High Speed Certied HDMI cables with low loss, high bandwidth signal
handling capabilities.

Switch Settings
● EDID: Choose TV mode, or Standard 1080p (STD) mode. In TV mode,
the 1398D automatically detects and stores EDID data from the device on
output 1. In STD mode 1080p/60 becomes the reference EDID for HDMI
sources on the 1398D input.
● SYS-RST: The 1398D checks the EDID of connected displays every eight
to ten minutes. Turn ON the SYS-RST switch to prevent the 1398D from
interrupting video and audio transmission to re-learn EDID settings each time
the source is switched, or a TV is hot-plugged to the distribution system.
Firmware Updates
Contact Audio Authority Technical Support at 800-322-8346 for information
regarding rmware updates.
Troubleshooting
● For 4K resolution, rst make certain that the input cable is as short as
possible, and that the cable is high-speed. HDMI cable design and quality
are extremely important in long cable runs where capacitance can severely
impact performance. Use a quality, high speed HDMI cable or high speed
HDMI extender that supports 4K.
● 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, you may need to divide
your distribution system into separate 1080p, and 2160p systems with a
source for each system.
● If some displays are not receiving video signal, or lose signal, check to see
that the correct input is selected.
● 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 display.
If a problem still persists after trying the above suggestions, contact the
Audio Authority Technical Service department via email:
[e-mail], or call 800-322-8346 or 859-233-4599.
