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 Amplifier 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 five 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.
