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

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.

HDMI / DVI HDCP SYNC OUTPUT POSITIONS POWER

EDID SWITCH HDMI INPUT HDMI OUTPUTS

POWER JACK

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.
