Audio Authority CMX-144 User Manual 7
Installation
The CMX-144 is easy to setup for simple or advanced installations. Perform the following steps.
1. Rack Mount Adapters. If the CMX-144 is to be installed
in a standard 19-inch equipment rack, remove the feet and
the cover screws adjacent to the front panel of the unit and
use them to mount Model 1192A rack adapters. Be sure to
place a spacer under the adapters at every screw location
– see illustration.
Note: Do not remove feet if using a rack shelf adapter.
2. Setting in Place. Place the CMX-144 on its shelf or in the
rack. If rack mounting, secure it to the rails with the screws
supplied with the rack adapter kits.
3. Initial Audio and Video Hookup. Connect and test
sources with a local video display in these steps. Note:
The CMX-144 may be connected using composite video
in place of coaxial digital audio. In this case, optical digital
audio cannot be used, and breakaway switching behaves
differently (See Appendix D).
a. Connect each source unit to its respective set of
CMX-144 input jacks.
b. Use high quality cable and keep the runs under 6 feet if possible, especially for component video connections.
c. Connect either, but NOT BOTH optical and coaxial digital audio. Connect all the other signals available from the
source unit: component video and analog audio.
d. Connect a video display and audio system to one of the zone outputs. Use optical and/or coaxial digital audio
outputs. The CMX-144 does not convert digital audio to analog audio, so connect analog audio to the TV’s
inputs if required.
e. Turn on the sources and CMX-144 temporarily for an initial test. Select each source to the connected TV and
sound system to verify basic functions. Remove power and continue installation.
4. Zone Connections and Testing.
a. Pull good quality 75 ohm coaxial cables from the main system to each zone location and terminate cables if
necessary. Test all cables for continuity.
b. Connect the CMX-144 power supply. The unit powers up instantly. Touch the CMX-144 power button; the green
power light turns off. Touch POWER again to turn on.
c. Apply power to all sources and video displays with associated equipment. Use the 1106 remote control to verify
video and audio signal integrity of sources at each zone location.
5. Tips for Using Infrared Control.
a. If you are using standard hand-held IR remote controls, ensure correct op-
eration by avoiding sources of light pollution such as Plasma and LCD TVs,
direct sunlight, uorescent light, etc. Experiment with the physical placement
of the IR receiver to avoid interference.
b. If a source of interference cannot be eliminated or avoided, use IR receivers
that block that type of interference, such as Plasma-proof or LCD-proof
receivers.
