2.0 GETTING THE BEST RESULTS
Many factors infl 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 fi 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 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 Amplifi 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 fi 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 amplifi 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 amplifi ers depends on the use of high quality HDMI cables that provide low loss, high bandwidth signal handling. The distance specifi cation cannot be guaranteed unless cables used throughout the system meet these high standards.
5.1 Notifi 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 fi 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 fi rst destination HDMI device’s EDID and records the value in the DA. If the fi rst detected output device is DVI, it passes on to the next device in sequence until the fi 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-defi ned resolutions and refresh rates so that a reliable connection can be made.
* The Extended Display Identifi 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 defi ned by a standard published by the Video Electronics Standards
Association (VESA). The EDID includes manufacturer name, product type, phosphor or fi 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, fi 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 Amplifi er is receiving power by looking at the power LED. It should be illuminated and not fl 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 amplifi er, you should attempt to determine what is wrong by fi 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 simplifi 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.
