1.0 INTRODUCTION

Thank you for purchasing this Model 1392A distribution amplier from
Audio Authority. This distribution amplier is designed to split an HDMI
signal from one source to two HDMI displays without signal degradation
or loss of encryption.

The 1392A is HDMI v1.3 compliant, supporting Dolby TrueHD and DTS­HD Master Audio. Ultra high bandwidth, equalized inputs, and amplied
outputs insure a awless installation even with long cable runs.

Audio Authority also offers an extensive line of audio and video
switchers, converters and distribution amps available for purchase online
at www.audioauthority.com.

1.1 FEATURES

• Distributes one HDMI source signal to two destinations

• Equalizer/extender circuitry allows up to 30m (100’) input cable length

• Outputs may be cascaded to create an extensive distribution network

• Supports 10/12 bit color depth display

• Supports 480i, 480p, 720p, 1080i, 1080p and many PC resolutions

• Supports Dolby Digital +, Dolby® Digital TrueHD and DTS-HD Audio

• HDMI version 1.3 compliant, HDCP 1.1 compliant

2.0 GETTING THE BEST RESULTS

Many factors inuence the quality and reliability of HDMI switcher
installations. Consider the following and take basic precautions
suggested below to ensure the best possible performance.

• Output display device. The quality of the output signal depends
largely upon the type and quality of the HDMI display device used;
some televisions simply look better than others.

• Distance between the sources and the display. Long distances are
possible, but premium quality cables and advanced HDMI extenders
with DDC correction may be necessary for the longest runs.

• Input/output connection cables. HDMI cable design and quality
are extremely important in long cable runs where capacitance can
severely degrade performance. Cables should be of the best quality;
low quality cables are susceptible to interference. Always use locking
cables or good strain relief methods to prevent cables from becoming
loose over time.

• Interference from nearby electrical devices can have an adverse
effect on signal quality. For example, older computer monitors often
emit a very high electromagnetic eld that can interfere with the
performance of video equipment in its proximity.

2.1 Resolution Tracking

HDTV signals can be output from the source at several different
resolutions and the 1392 can sense and accept any standard resolution.
However, on the outputs, the DA must sense the resolution capabilities
of all of the display devices connected to it and then set the resolution of
all outputs to the resolution of the display having the lowest resolution
response characteristics. This behavior insures that all displays can
produce a picture. It is best to use display devices having the same
maximum resolution; just one display with lower resolution capabilities
causes all of the other displays connected to the DA to receive that same
low resolution.

3.0 CHECKING PACKAGE CONTENTS

Before attempting to use this DA, please check the packaging and make
certain the following items are contained in the shipping carton:

• HDMI Distribution Amplier

• 5 VDC Power Adapter

• User Manual

Note: please keep the original packing material in case the unit ever needs to be

returned. If you nd any items are missing, contact Audio Authority immediately. Have
the model number and invoice available for reference when you call.

4.0 CONNECTING THE HARDWARE

Please study the front and rear panel drawings and become familiar with
the signal input, outputs and power input.

The 1392A has a single HDMI input and two HDMI outputs. The Power
LED indicates that the unit is receiving power.

• Connect an HDMI approved cable from the HDMI source to the input
of the DA. Cable length can be up to 30 meters – preferably shorter.

• Connect the outputs of the DA to their destination devices using HDMI
approved cables no more than 30 meters long.

• Connect the power adapter to the AC source and then to the DA.

• Turn on the HDMI source and HDMI destination devices and observe
the source signal on the inputs of all of the destination devices. The
DA’s front panel LEDs will light indicating which outputs are active.

• Make certain that the HDMI cables are securely plugged into the
source and display devices as well as the HDMI DA. Always use high
quality cables, and the shortest length possible, for best results.

HDMI INPUT POWER OUTPUT POSITIONS

7

The unit begins to function as soon as the AC adapter is connected
to the unit and AC power. There is no power switch; no other operator
interventions necessary.

Note: Proper operation of HDMI distribution ampliers depends on the
use of high quality HDMI cables that provide low loss, high bandwidth
signal handling. The distance specication cannot be guaranteed unless
cables used throughout the system meet these high standards.

5.0 TROUBLESHOOTING

• For 1080p resolution, rst make certain that the input cable is as short
as possible and none of the output cables are more than 30 meters
long. HDMI cable design and quality are extremely important in long
cable runs where capacitance can severely effect performance. Our
1391A Extender/DDC Corrector may be a necessary accessory to use
in extreme length applications.

• 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 you still experience problems using the distribution amplier, you
should attempt to determine what is wrong 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.

• Remember that HDMI devices communicate with one another so the
source device and all destination devices must be fully HDMI and
HDCP compatible.

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.
