Model 1398C

4K/2K Distribution Ampliﬁer

Introduction

Thanks for purchasing the Model 1398C UHD distribution amplier from Audio

Authority®. The 1398C is designed to split a 4K HDMI® signal from one source

to a wide spectrum of HDMI displays in retail demo environments. It is the ideal

solution for merchandising HD displays using the latest content at the highest

resolutions, and even 3D. Display-source compatibility is ensured by the

1398C’s multiple EDID options. Daisy-chain multiple 1398Cs or create a hub-

and-spoke layout for large distribution systems.

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 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 premium 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 high

speed premium cables designed to handle video resolutions such as 1080p, 4K,

3D and Deep Color; 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 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.

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. This 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 126.

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.

Wiring the System

● Switch off all devices, including monitors.

● Connect an HDMI approved high speed cable from the HDMI source to the

input of the 1398C. Cable lengths should be kept as short as possible.

● Connect the outputs of the 1398C to their displays or other devices.

● Make certain that the HDMI cables are securely plugged into the source and

display devices as well as the 1398C. Always use high speed quality cables,

and the shortest length possible, for best results.

● Connect the power adapter to the AC source and then to the 1398C.

● 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 high speed quality HDMI cables with low loss, high bandwidth signal handling

capabilities.

Notes:

A. Automatic EDID learning will detect all of the connected HDMI equipped displays and

analyze the content of EDID. The display that has the lowest resolution support will be the

reference EDID for incoming HDMI sources.

B. While connecting a new monitor to the 1398C under mode 6 (Auto EDID) & mode 7

(EDID learning mode), you may experience a short period of time without any program

material viewed on the display. The splitter will do Automatic EDID learning which

analyzes the newly connected monitor to see if the EDID for the HDMI input must be

updated.

Firmware Updates

Contact Audio Authority Technical Support at 800-322-8346 for information

regarding Firmware Updates.

Troubleshooting

● For 4K resolution, rst 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 effect performance. Use a quality high speed HDMI

cable or high speed HDMI Extender that supports Ultra- HD.

● 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 4K 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: support@audioauthority.
