Can anyone help me with this because I’m as confused as a teenaged girl on birth control. I’m running a cheap chinese transmitter with a 1/4 inch analog audio input. I’m also running breakaway broadcast processor with stereo tool. My input is the "What U Hear" stereo mix from an SB Audigy card. My output to the transmitter is a 192 KHz onboard Realtek. Both run on the same piece of shit computer. How the hell do I get the RDS to work with stereo tool? What should the following settings be?
Breakaway I/O config"
Input:
RDS In:
L/R Out:
MPX Out:Stereo Tool (transmitter config screen)
"Sound card (must be 192 KHz capable)": ????????????????????

+A mysterious drop down to select a sound card
"Enable low quality and low letency extra output channel": ???????????????????????? :-O 🙁 🙁 🙁

WTF???????????????
If your transmitter has no stereo multiplex input, it may not be possible to have RDS.
So select a sound card, but too bad if it isn’t up to 192 khz. If so, no wonder that you can’t have RDS. But you may be trying to run two sound cards at once and causing conflict. Also, I’m not sure if it’s good to use Breakaway and Stereotool at the same time. Maybe someone else would know.

A MPX signal already include the stereo audio signal. What do you mean with stereo multiplex input?
Alcyone:
What motherboard are you using, or what Realtek chip is used?
Many onboard audio chips do not support 192 kHz output.What OS are you using?
Hi thanks for the responses.
My transmitter only has an analog 1/8 inch input for audio and an 1/8 inch input for the mic. The mic input is unused.
My motherboard is a gagabyte GA-X58A-UD3R with an Intel chipset. I’m running windows 7 professional 64 bit.
I don’t know what specific model the Realtek HD audio is, but Speaker Properties in windows show the output as being 192000 Hz capable, which it is set at. It’s currently running at 16 bit but the output is 24 bit capable. This output goes direct to the transmitter.
The input sound card (which I’m using the stereo mix from) is only 92000 Hz capable.
I was able to get the RDS light on a car receiver to flash repeatedly before it showed all blanks as the text, but the sound was in mono and I was never able to get further than that.
Can RDS be passed through the regular analog input to the transmitter?

Nope.You should think about adding an input audio jack to the front/back so you can input MPX directly. You’ll need to download a schematic for the transmitter if you don’t already have one, to help you figure out where the stereo generator is, and if there’s any effects/processing after it. You want to have the jack connected after all of that. Right before the FM exciter. 🙂
