8 Audio Authority Model 1156 and 1166 User Manual
Audio Authority Model 1156 and 1166 User Manual 9
Installation
You may wish to consult with a qualified custom electronics installer if you are inexperienced with DVI,
HDMI/HDCP, component video connections and compatability. If you are installing 1170 or 1176, you should
be familiar with Cat 5 cable termination tools and techniques.
Note: This manual addresses Model 1166 and 1156 generally but also include references to DVI capability
which is available only on the 1166. If you are installing a Model 1156, ignore the references to DVI.
Note: Instruction steps calling for IR learning or other setup can be performed ahead of time using the
Model 1166PC Setup Application.
1.
Pre-Setup.
If the setups were previously constructed using the Model 1166PC Setup Application, plug
the Flash Card containing the setup file into the memory slot in the upper right corner of the back of the
Model 1166. Temporarily apply power, go to the SETUP menu, choose SAVE/LOAD FILE, and fol-
low the instructions on the screen. The 1166PC setup application is available as a free download from
www.audioauthority.com.
2.
Stacking.
Follow these steps if you are installing this product in a stack containing Models 1170, 1176 or
other Audio Authority stacking models.
a. Lay the Model 1166 upside down on a protective surface, such as a terrycloth towel.
b. Remove the four feet and the bus port cover and save them and their attaching screws for later use.
c. Plug one end of the bus cable (purchased separately) into the connector visible through the bus
port—apply enough pressure with fingers or a wooden or plastic tool to assure that the plug is com-
pletely seated. This bus cable carries component video, digital audio and analog audio signals from
the 1166/56 to the 1170 or 1176 for distribution to 9878 Wallplates.
d. Turn the next product to be stacked upside down (e.g. Model 1170 or 1176), thread the bus cable
through its bus ports, and engage its four threaded studs with the four threaded holes in the Model
1166 formerly occupied by the feet.
e. Tighten the hex head screws in the bottom of the stacking product in sequence a few turns each, until
they are all snug.
f. Plug the bus cable into the connector like before. Continue this stacking procedure until all units
have been stacked. Always plug the last connector of the bus into the bottom unit, pushing any ex-
cess cable into the empty space inside the unit. View the bus through the bus port to be sure all plugs
are fully seated. To disconnect a bus plug, squeeze the side latches.
g. Install the bus port cover and feet you removed from Model 1166 on the bottom unit and turn the
stack right side up.
h. Set the Address dial on each Model 1176 (Model 1170 does not require addressing)--set the upper-
most Model 1176 address to “A”, the next one to “B”, and so on.
i. Temporarily plug in the power supplies of all units to a plug strip so that you can turn them all on at
one time. The opening screen on the Model 1166 display will indicate that the unit is powered and
how many Model 1176s have been recog-
nized. If this number is different from the
number actually present, look for the bus
not being fully plugged into a unit or a unit
incorrectly addressed.
Model 1170s
are not
indicated on the opening screen.
