2.0 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.
•
Output display device.
The quality of the output signal depends
largely upon the type and quality of the HDMI display device used.
For instance, some televisions just look better than others.
•
Distance between the DA 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.
Low quality cables are susceptible
to interference. They degrade signal quality due to poor conductor
matching and can cause elevated noise levels. Cables should be of
the best quality.
•
Interference from nearby electrical devices
can have an adverse
effect on signal quality. For example, an older computer monitor often
emits very high electromagnetic  elds that can interfere with the
performance of video equipment in its proximity.
2.1 Resolution Tracking
Since HDTV can be output from the source at any of several different
resolutions, the 1390 series DA 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
lowest resolution response characteristics. This behavior insures that all lowest
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
N
ote: 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 inputs.
The 1394 and 1398 are functionally identical with the exception of the
number of outputs. Both have a single HDMI input and a 5 VDC power
input socket. LEDs on the front panel indicate when the DA is furnishing
a signal to an HDMI compliant device.
•
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.
The unit begins to function as soon as the AC adapter is connected to
the unit and AC power. There is no power switch. There are no other
operator interventions required with the possible exception of the EDID
jumper (see 5.0 Operating the Unit).
4.1 Using the Positive Cable Securing Feature
If HDMI cables are used that are equipped with locking type connectors,
remove the Philips head screws from the rear of the unit just above the
HDMI connectors and replace them with the hex nut/screws included
with the accessory pack. After screwing these into the threaded holes
vacated by the Philips head screws, the hex nut provides a threaded
receptacle for the screw that is part of the locking HDMI connector on the
cable. Plug in the cable’s locking HDMI connector and secure it to the
unit with its integral screw.
4.2 Optional Rack Mount Kit
The distribution ampli ers can be mounted in a standard 19” equipment
rack. Attach the furnished rack ears the sides of the unit and then attach
the unit to the 19” rack using the furnished hardware. To mount the 1394
DA in a rack, the rack mount kit must be used.

5.0 OPERATING THE UNIT
*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.
5.1 Noti cation LEDs
There are LEDs for each output which show whether or not the output
has successfully made a connection with the destination device. In
addition to these, four more LEDs provide the following information:
•
HDMI / DVI
LED shows whether an HDMI or DVI signal is being
received.
•
HDCP
LED shows if the signal is encoded with HDCP (High-bandwidth
Digital Content Protection) signals.
•
SYNC
LED shows if the HDMI signal has synchronized.
•
POWER
LED shows the unit is receiving power.

5.2 EDID Jumper Operation
On the rear of the unit you’ll  nd an EDID* Jumper. The default factory
setting for the EDID Control Jumper is
AUTO
and you should leave it as
it is if the display is operating properly.
The EDID jumper controls whether the DA determines the connected
devices’ EDID information automatically or uses an internal information
table. Switch to
INT
(Internal) to use the built-in EDID information table if
communication problems occur.
When the EDID control jumper is in AUTO position, the unit detects the
 rst destination HDMI device’s EDID and records the value in the DA. If
the  rst detected output device is DVI, it passes on to the next device in
sequence until the  rst HDMI compliant device has been detected.
If the DA cannot reliably determine the destination device’s EDID through
the information exchange, switching to the internal table (INT) allows the
DA to run through a range of pre-de ned resolutions and refresh rates so
that a reliable connection can be made.
* The Extended Display Identi cation Data (EDID) is a data structure
provided by a display to describe its capabilities. It’s what enables the
DA to know what kind of video display is connected to the unit. EDID
is de ned by a standard published by the Video Electronics Standards
Association (VESA). The EDID includes manufacturer name, product
type, phosphor or  lter type, timings supported by the display, display
size, luminance data and (for digital displays only) pixel mapping data.

6.0 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 capable.
In addition, HDCP encryption requires processing dependent on the
equipment you have connected to both the source and destination
devices.
If the problem still persists after trying the above suggestions, contact the
Audio Authority Technical Service department via email: support@audioa
uthority.com, or call 800-322-8346 or 859-233-4599.
