My LPFM Build In Washington State KAPY 95.5

Hi,
Ok for a start, you will not need the Behringer 1202 at all. Here is how you should configure your setup..

To begin with your computer upon which you have Breakaway installed, MUST be capable of 192Khz operation. The very best soundcard to use is a Marian Trace Alpha. If you can’t source one of these then I recommend an ESI Juli@ which are easy to source. For ease, I shall refer to the Juli@ card but if you get a Trace alpha then replace each reference as appropriate.

If your playout is on the same PC as you are running breakaway, you will need to set the Zara output to "Breakaway Pipeline 1".
If your playout is on a different computer and/or you have a mixer in your setup, the audio from this must be connected to the input of the Juli@ card.
This is where the magic begins.. The computer with breakaway running, not only processes your sound above and beyond industry standards, but it also acts as your stereo coder (and optionally RBDS/RDS coder if you plugin the Airomate software for €25).
You then connect the output of just one channel of the Juli@ card into your exciter (remember this is now a multiplexed signal). You will now be transmitting in stereo with fully processed audio.

You should think of the computer running Breakaway with the Juli@ (or Trace Alpha) card fitted as the equivalent of an Orban Optimod 8500 (only better). You connect L/R stereo audio into it and you get fully processed and multiplexed (transmitter ready) audio out. It almost sounds too good to be true I know but this is how advanced Breakaway is as a product.
It’s best to have the breakaway PC doing this job standalone but it should be ok to run a basic automation system such as Zara on the same machine if you wish or if you need to.

To answer your question "Is there a software based stereo generator that I can utilize?" the answer is YES, Breakaway has this built in. There are a handful of other programs which can do this also but Breakaway stands head and shoulders above all of them as the only professional quality processor AND stereo coder out there.
The most important thing to understand is that you must have a 192Khz output soundcard (most standard PC soundcards are 48Khz). Without this, none of this is possible.

I hope this helps.

Breakaway outputs a completely compliant composite FM signal, aka MPX. It also has inputs for an external RTS (software or "hardware" can be used). It has settings for both 50uS and 75uS pre-emphasis.

It completely takes the place of the stereo generator because IT IS a stereo generator. A totally compliant one with almost perfect filters too. Someone would have a VERY hard time creating one as high quality in analog form. 😉

The only thing you would ever need to do after a stereo generator is SCA injection, but that’s still done analog many times, and there’s lots of FM stations that don’t have any SCA side-band.

[quote author=”just passing thru”]Yorkie,
Thanks for the great response, that has answered my questions . Now I will focus on getting, the Juli@ soundcard TO START, since I can use it down the rd with my automation computer, which will input into computer #2, which will utilize BBP. I will need to make/buy a jumper that is a 1/8 stereo jack to BNC, which is the MPX input on my Energy-Onix.
EDIT: After talk with my consultant, he has instructed me to ask the following question.
Does BBP generate a stereo sub-carrier and if so how does it take the place of a stereo generator?
Are you in the states?

Hi Guy, yes, Breakaway (Broadcast) does generate a stereo subcarrier and it does totally take the place of a traditional hardware generator. It takes the place of a hardware stereo generator by fulfilling exactly the same function, in the same way that an automation playout PC replaces a hardware CD player, or a PC can be used instead of a pocket calculator, a typewriter or a DVD player etc… etc..

I am not in the US, I am in the UK.

Not really. Used to see Scooter Chapman from time to time, but it’s been awhile. Now busy with some radio projects in Shelton. Keep in touch though, if there’s anything I can help you with… even brainstorming.
