Video Distribution Amplier

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:

● 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.

● 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

from the On Screen Display (OSD).

● All: Set the 4K conversion mode for all of the

outputs. Setting this to bypass will disable the

4K conversion function.

Note: Making changes to this setting will

overwrite the individual output’s settings.

● Out A-H: Set the 4K conversion mode to use for
