* IN RGB mode, be sure to connect H and V to the analog left and right audio jacks.

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:

support@audioauthority.com, or call 800-322-8346 or 859-233-4599.
