Introduction

Thanks for purchasing an Ultra HD distribution amplier from Audio Authority.

The 1398D, 1394D, and 1392D are designed to split an Ultra HD or 4K HDMI®
signal from one source to a wide spectrum of HDMI displays in retail demo
environments. This family of products is the ideal solution for merchandising
Ultra HD displays using the latest content at the highest resolutions and refresh
rates, including 2160p@60Hz.

Display-source compatibility is ensured by the distribution amplier’s multiple
EDID options. Daisy-chain multiple distribution ampliers or create a hub-and-

spoke layout for large distribution systems.

Features

and 4096x2160@24/25/30/50/60Hz

● HDCP 2.2 compliant

● Wide frequency range: 25MHz~600MHz

● Video bandwidth: 18Gbps

● Supports default EDID and has the ability to learn the EDID of displays

● Mini-USB rmware update for expanding compatibility

● Supports all bitstream audio formats such as Dolby Digital and DTS

● Compact footprint and easy installation

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.

● SYS-RST for 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, set the SYS-RST switch to ON (SYS). 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 be shown at
a lower resolution.

● 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.

● 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 - 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.

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 the source is set 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 1080p, all of the displays will receive only 1080p 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.

● 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 of the DA. Cable lengths should be kept as short as possible.

● Connect the outputs of the DA to displays or other devices.

● Make certain that the HDMI cables are securely plugged into the source and
display devices as well as the DA. 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 DA.

● 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 certied high speed HDMI cables with low loss, high bandwidth

signal handling capabilities.

Switch Settings

● EDID: Choose Standard (STD) or TV mode. In TV mode, the DA
automatically detects and stores the output 1 sink EDID data (e.g. a TV).

Switch to STD mode for 1080p output.

● SYS-RST: The DA checks the EDID of connected displays every eight to ten
minutes. Set the SYS-RST switch to ON to prevent the DA 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, use premium certied high speed HDMI cables and a
high speed HDMI Extender (if needed) that supports Ultra-HD. 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.

● 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 if

they are on the wrong input.

● 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.

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.
