Audio Authority 1185ci Mulit-mode HD Distribution Amplifier

Audio Authority 1185ci Mulit-mode HD Distribution Amplifer
1x4 DA for HD as well as Analog and Digital Audio

The versatile 1185ci Multi-mode HD Distribution Amplifier can distribute both high-definition video and audio signals to as many as four destinations, without signal degradation. It features ultra-wide video bandwidth, making it equally proficient with either Y/Pb/Pr or RGBHV video, easily handling all HDTV resolutions, including 1080p. For RGBHV applications, the analog audio channels can be configured to handle the H and V sync channels.

In addition to pristine video, the 1185ci can also deliver audiophile-quality analog stereo and digital audio. It seamlessly converts between optical and coaxial digital audio, providing an elegant solution to many system integration problems.

The 1185ci features rugged all-metal construction and a compact form factor: 1.75" H x 10.5"W x 4.1" D.

Like most Audio Authority products, the 1185ci comes with a one year limited warranty from the manufacturer.

Audio Authority's Description

1:4 HD Component and Audio Distribution Amplifier

Model 1185ci

  • 1-in, 4-out distribution amplifier with component video, digital coaxial, digital optical, analog audio
  • Switch enables VGA operational mode with breakout cables
  • Digital coaxial audio pathway can support composite video
  • Built-in cross-conversion of digital audio
  • Made in the USA


The 1185ci is the most versatile distribution amplifier designed specifically for the needs of custom home and commercial systems integrators. Inexpensive enough to keep "on the truck", and versatile enough to meet almost any challenge by splitting video and audio signals to four outputs. High bandwidth component video pathways handle up to 1080p resolution, while analog audio, digital optical, and digital coaxial audio are also supported. With the flip of a switch, the 1185ci enters RGBHV mode, and can be used to distribute VGA signals through its video and analog audio paths (requires breakout cables - sold separately).


Key Features

  • Selectable YPbPr component or RGBHV VGA modes
  • High bandwidth video paths preserve original picture quality
  • Supports component video (YPbPr) up to 1080p
  • Digital audio (coaxial and optical)
  • Automatic digital audio cross-conversion
  • Stereo analog audio
  • Made in the USA


  • Component video (YPbPr) - 1/4
  • Digital audio (coaxial and optical) - 1/4
  • Analog stereo audio (L/R) - 1/4

Model 1185ci Signal Configuration 

Audio Authority 1185ci Signal Configuration Table

This distribution amplifier is designed to be used in a one-input, four-output configuration, and is not intended for use in a cascaded series or chain of amplifiers. If chaining multiple amplifiers together is necessary, we suggest the Model 9851or Model 985DTO as alternatives, as they offer devoted bus outputs.
