4.0 INSTALLATION
Connect the input port to a source of Component or RGB video
using high-quality patch cables. Connect each of the four outputs to
its destination television using coaxial cable suitable for baseband
video, such as RG-59 with a solid copper center conductor. Do not use
RG-6 or steel-core cable. Plug the included 12 volt DC power supply
into the Model 1185ci Power jack and plug the wall adapter into an
AC outlet.
4.1 VIDEO APPLICATIONS
The 1185ci may be used for either YPbPr or RGBHV video. When
using component video, set the mode switch to YPbPr and connect
audio and video cables as indicated on the panel legends. In RGB
applications, set the switch accordingly and connect the red green
and blue video cables acording to the jack color code, and connect
the horizontal and vertical sync to the wideband L and R audio jacks.
As a result, only digital audio pathways are available when using
RGB mode.
5.0 TROUBLESHOOTING
• Ground loops often cause disturbances such as hum in the audio
channels, rolling bars in the picture, or jitter in RGBHV video. In
the event a ground loop interferes with downstream television
performance, add an Audio Authority Model 1184 Hum Eliminator
at each television that exhibits the symptoms.
• Make certain that the Distribution Amplier is receiving power by
looking at the power LED. If the DA is not receiving power, check
the AC outlet or suspect the power supply.
• In RGB applications, be sure all ve video cables are connected
– RGB requires separate cables to pass H and V (horizontal and
vertical sync) in addition to the cables for red, green, and blue.
Connect the H and V cables to the R and L audio jacks.
If the problem still persists after trying the above suggestions,
contact the Audio Authority Technical Service department via email:
[e-mail], or call 800-322-8346 or 859-233-4599.
