Audio Authority 1374A Manual

HDMI™ in the Showroom
HDMI technology is now able to meet the demands of the audio/video showroom. using audio authority
and expertise, your showroom can display 1080p, Deep Color, and all of the other benefits of HDMI 1.3. Follow
these guidelines to ensure a smooth installation.
1. each display should be tested with the source(s) being used to ensure basic compatability before connecting them to a
distribution amp and/or switcher. not all HDMI components and displays are compatible.
2. since all of the displays will be receiving the same video signals from the source, make sure the source is set up to output
the highest resolution that all of the displays can accept. for instance, if one of the displays connected to the distribution
system can only accept a maximum resolution of 720p, all of the displays must receive only 720p video signals. You may
consider creating two or three different distribution systems with separate source outputs at different resolutions so that you
can adequately demonstrate each HDtV at its highest resolution.
3. Audio Authority HDMI distribution amplifiers allow up to 30 feet of premium cable between the source and the amplifier
input, and up to 30 feet of premium cable between the outputs of each distribution amp to each display. Use of high
resolutions, refresh rate, or deep color may limit maximum cable lengths. If greater cable lengths are required, the Model
1391A Extender with DDC correction can be insterted into any signal path to increase the distance up to 130 feet. If coaxial
cables are available, Model HCX-11 can be used to extend signals up to 330 feet.
4. Since HDMI connectors can sometimes become loose, use locking cables or mount switchers and distribution amplifiers to
a flat surface and add strain relief tie-downs a few inches away from every HDMI cable connector.
5. If you plan to install a very large HDMI signal distribution network, you should carefully plan to work within the HDcP
system limitations (see page 4). each system is limited to 127 HDcP rx "nodes". every HDMI device with an HDcP rx
chip counts as one node, including tVs, distribution amps, and switchers. audio authority can help you correctly calculate
the nodes and create a system optimized for maximum capacity.
Application #1
this simple system distributes the HDMI signals from an HD source, in this case a Blu-ray disc player, to four HDtVs. connect
the source output to the input of an HDMI distribution amplifier, then connect HDMI cables to each TV.
