C. Install the Low-Level Buses
• The Low-Level buses carry signals from the Source Product Group to the Receiver Product Group via RCA patch
cables. Be sure to observe IN/OUT bus wiring on 955 and 945 modules.
• The Left and Right Audio Bus begins in the Source Product Group, and continues through the Bus In and Bus Out
jacks of the 980EZ and then on through the Receiver Product Group.
• The Digital Audio Buses follow the same route, but DO NOT loop through the 980 module. Connect them directly from
the Digital Audio Bus Out jacks on the 955 modules to Digital Audio Bus In jacks on the 945 modules.
• Composite Video Bus connects to the yellow Composite Video jacks on the 955 modules, and on to the TV monitor
( See Figure 33. ) For HDMI switching, see audioauthority.com/hdmi-demo for details.
• The Subwoofer Output Bus is connected from one 945 to the next, and finally ends up at the Subwoofer
Product Group.

D. HDMI Video Distribution
The Audio Authority Distribution Amplifiers are easy to install. Some other rules are as follows:
• Each distribution amp should be permanently mounted as close as possible to the products it feeds, and within reach
of an AC power outlet.
• If any ports are unused, leave them vacant. Do not plug in any open-ended cables.
See 1398C manual and website.
