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.

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

2. Place a four or eight output distribution amp near the televisions they will serve. Remember that if any amp output connects
to the input of another amp, you must subtract one from the number of outputs available for video displays. This system
has 56 nodes, but eight of those nodes serve other DAs; therefore this system has a capacity of 48 TVs.
