Review of Audio Authority 9A60 Transcoder
<< Back to RGB to Component Transcoder
Tip by Dave Richardson: Equipment used
in my evaluation
- Unity Motion Monitor
- Unity Motion receiver x 2
- C-Band 10' Dish
- UM 1 Meter Dish
- RCA 18" dish
Using one UM receiver I connected the RGB(VGA) output to the AA converter then to the
YPbPr1 on the UM monitor. Using the other UM receiver with the YPbPr output engaged I went
to the YPbPr2 on the UM monitor.
While watching NBC-Leno, ABC-Sat. movie, and the HBO demo channel I didn't see any
noticable difference while switching between the two UM receivers. For $130 what more can
you ask for?
Two thumbs up for AA
Instructions were in my box and it goes as follows:
"How to use the Model 9A60 VGA-To-Component Video Adapter
The Model 9A60 adapts VGA-type RGBHV video sources to YPbPr component video for use
with High Definition Television (HDTV) monitors. With compatible sources and monitors, it
permits HDTV images generated by a set top box (STB) or personal computer to be displayed
on a HDTV monitor that is capable of displaying the image format delivered by the source.
The 9A60 is not a format converter it passes the horizontal and vertical
synchronization timings and pixel content to the outputs with modification. For example, a
1080i RGBHV source with a 9A60 will require your HDTV monitor to accept 1080i YPbPr
component video input. Generally, 1080i, 720p and 480p sources may be displayed on
monitors designed for the desired format using the 9A60. However, some combinations of
sources and televisions may produce undesired artifacts or fail to work at all.
Regarding the RCA DTC-100
The 9A60 in most cases will provide good results when interfacing the DTC100 with HDTV
televisions. If the picture is not centered correctly, call your dealer for instructions
on adjusting the DTC100 via its service menu."
For HDTV Computers
For viewing DVDs, use software such as PowerStrip to set the output parameters of a
high-perfermance video card to provide an HDTV format acceptable to the television. For
displaying normal PC video on HDTV sets for games and other PC applications, make sure the
television can accept a 480p input. Remember HDTV monitors that can accept progressive
(non-interlaced) video generally have a maxium vertical refresh rate of 60HZ; avoid
sending higher rates from your PC.
Highlighted Specs:
Output: YPbPr video on 3 gold plated RCA jacks
Sync on Y output: Bilevel .6uSec negative H sync and negative Vsync
Video bandwidth: -3db @ 250MHZ

The vendor selection for the converter/cable for the other video products is VERY
limited. In fact, there is only one manufacturer right now that can answer that
requirement: Audio Authority.
ADJUSTMENTS ON DTC-100:
Apparently, some tweaks need to be made on the DTC-100 to be
centered properly on most RPTVs. If the image on your TV with the AA and DTC-100
combo is not correct, you can correct it by doing the following on the DTC-100:
- Press the INFO button and the DOWN ARROW key simultaneously ON THE
UNIT.
- Use the DOWN ARROW to move the picture left or right.
* This procedure applies whether you have the AA or not.
The center issue is a function of the DTC and not the AA. Also, if you have the DTC
firmware 4.037b or higher, then you can adjust the raster via the DTC onscreen menu.
ADJUSTMENTS ON THE
TRANSCODER:
This is a note from Audio Authority for tweaking the
transcoder. This was in response to an owner experiencing synch problems on his TV.
"Sorry to hear about the difficulty you are having with your video setup. There's
probably nothing wrong with your adapter. Most likely, your display will not lock to the
bi-level sync output of the 9A60. Some displays require tri-level sync at high resolutions
like you're using. If you are interested, you may try manually adjusting the sync pulse
width of our 9A60. To do this, remove the cover and locate a small rotary potentiometer
(there's only one, it's labeled R7). Note the position of the indicator before making any
adjustments. Next, connect your video signal to the display and using a small screwdriver,
adjust the potentiometer one way and then the other. If your picture stops rolling, leave
the dial in that spot. If you have no luck, return the indicator to it's original
position.

ADJUSTMENTS ON YOUR TV:
If above suggestions do not correct the problem, adjustments may
also be needed on your TV. This may require that you conduct geometry/convergence
adjustments on your TV.
Each TV is different so results will vary.
