1.0 INTRODUCTION
Thank you for purchasing this Model 9A67 VGA to Component Video
Signal Converter from Audio Authority. This product is designed
to convert RGBHV video sources to YPbPr Component video for
use with HD television displays. With compatible sources and
televisions, it permits video images generated by a set top box (STB)
or personal computer to be displayed on an HDTV that is capable of
displaying the image format being produced by the source. Audio
Authority also offers an extensive line of audio and video switchers,
converters, and distribution amps available for purchase online at
www.audioauthority.com.
The 9A67 is not a format converter. It passes the horizontal and
vertical synchronization timings and pixel content to its outputs
without modication. For example, a 720p RGBHV source with
a 9A67 will require your HDTV monitor to accept a 720p YPbPr
component video input. Any resolution and refresh rate adjustments
that are necessary for compatibility with the display device’s inputs
must be done in the source device.
Generally, Model 9A67 will enable any progressive-scan video source
to be displayed on a video display designed to accept the source’s
video output format. However, some combinations of sources and
televisions may produce undesired display artifacts, shifted image, or
fail to work at all.
1.1 FEATURES

2.0 CHECKING PACKAGE CONTENTS
Before attempting to use this unit, please check the packaging and
make certain the following items are contained in the shipping
carton:
• 9A67 video converter
• 12V DC power adapter
• User manual
Note: Please keep the original packing material in case the unit
ever needs to be returned. If you nd any items are missing,
contact Audio Authority immediately. Have the serial number and
invoice available for reference when you call.
3.0 INSTALLATION
Connect the 9A67 to the video source using a VGA cable and apply
power using the included 12 volt power pack. Connect the output of
the 9A67 to the Component Video input jacks of the HDTV. Power
up the system and check for a picture. If none appears on the HDTV
set, turn off the power, then check and correct resolution/format
compatibility before restarting the TV.
Caution: Do not operate the monitor for extended periods with an
unstable picture – incompatible settings can cause damage to your
display device.
3.1 OPERATION
The 9A67 continuously measures the number of horizontal lines
per eld (interlaced) or frame (progressive) and displays the format
having the closest number of lines. HD formats are indicated as
either interlaced or progressive. Inputs recognized as non-HD
formats, such as those used for computer imaging, are displayed as
Format: Interlaced
Output Resolution: 1,080 Lines

the number of lines, alternating with an “Err” message. A constant
Err message indicates that the 9A67 format detector does not
recognize the input format. If the format reported by the 9A67 is not
one that your monitor or projector can display, you must change the
format being output by the source.
3.2 HDTV-CAPABLE COMPUTERS
For viewing DVDs, use software such as PowerStrip or DisplayCongX
to set the output parameters of your computer’s high-performance
video card to an HDTV format acceptable to the HDTV set. A
common format is 1280 x 720 @ 60Hz. For displaying normal PC
video on HDTV sets for games and other PC applications, make sure
the HDTV can accept the progressive-scan format of the source.
Remember, HDTV sets that accept progressive (non-interlaced)
video generally have a maximum vertical refresh rate of 60Hz; avoid
sending higher rates from your PC or damage may result to your
HDTV set.
4.0 TROUBLESHOOTING
• If no picture is visible make certain that the 9A67 is receiving
power by looking at its LED display. It should always display
something if its power supply is connected. If no picture appears,
disconnect the 9A67 power and adjust the source to a compatible
video format. Caution: Do not operate the TV for extended
periods with an unstable picture – incompatible settings can cause
damage to your HDTV set.
• A constant “Err” message indicates that the 9A67 format detector
does not recognize the input format. An Err message alternating
with the number of lines indicates the input signal is a non-HD
format (e.g. a computer resolution). If the format reported by the
9A67 is not one that your HDTV set or projector can display, you
must change the resolution and/or format being produced by the
source.
• If your computer does not allow a resolution compatible with your
display, you must install third party software such as Powerstrip
(Windows®) or DisplayCongX (Mac®). For more information on
using computers with HD displays, download the article The Best
of Both Worlds: Viewing a PC on a TV from audioauthority.com.
