MPX and stereo out of phase

[in2beats]

thank you for your response

@in2beats, I would recommend you to install, if you haven’t already, other demo applications for this purpose, and then check for possible phase deviation. There are at least three applications on the internet that can be downloaded and tried. That way you will be 100% sure that the cause is not hardware

please could you please point me in the direction of the “demo applications “?

I still claim that this is software for enthusiasts, which does not mean that it is not suitable for professional use. It just means that you need to sit down and spend a certain number of hours to get it right. And that’s acceptable in my opinion considering the price and what it offers.
Ask yourself how many stations have a qualified person who will do this job or who is ready to spend hours tuning the application in addition to their regular work.
That’s why, as a rule, in broadcast systems, you order hardware from a renowned manufacturer and possibly a custom preset, screw in the BNC and power supply, adjust the mpx level, and there’s no more need to poke around and worry if Windows or some of the PC hardware will scream. But of course, it costs money.

as stated before I have spent hours messing around and tuning to try and get it right, I have built 3 different machines, used an oscilloscope, tried new and different sound cards, and bought equipment like the pira to set it up correctly,i understand it is a cheeper option for decent audio but at the expence of time to set it up , the only person that would be qualified to set this up is either someone who has built loads of audio processors using breakaway or someone that designed and built the software or someone that has read the user manual “there is not one” so there really is not much use for this in a professional setting unless you are lucky enough for it to work straight after install if it does not then there is little support and you might get accused of using software from a place we can’t talk about, all I have asked is how to adjust the phase, or what effects the phase, it has taken months and 15 posts to be told try a different way to measure the phase difference and try different hardware,

Just a little more about the pilot. If the equipment has a good linear characteristic (no phase distortion/amplitude deviation within the baseband), there is no question of going over 75KHz with a nominal pilot value of 9%. If there are overshoots then the problem lies in the sound card, STL or TX, which can be partially corrected within the BAO software.
And yes, the pilot can be regulated without Leif’s intervention, you just need to think a little about how to do this inside the software.

the pilot level is on a slider “Leif put one in the software for me as I said before so I don’t have to think about that. ? are you hinting at something else?
I’m not getting any overshoots.
I’m not using a Beringer sound card using the ES9018K2M DAC chip, 24bit 192Khz sound card as advised by leif , and I’ve tried 2 new ones,
its just phase that is out
this is like guess what?
please can anyone tell me what affects the phase being out on breakaway one ,
if they are both generated in the software, and the software controls this then what setting or adjustments affect the phase, and the tilt I have tried, changing the frequency of the audio, doing a sweep, and changing from a square wave, I have changed about every setting known to man on 3 DIFFERENT installs with the same results,

At the end, if your phase correlation with other applications is good, I don’t think that you will find solutions by writing here. Only direct correspondence with Leaf remains, no matter how slow it may be.

I tried this , got nothing back,
as I previously said this forum does not even exist on the website, Leif does not answer, so basically the end of the road, I bought something and the support has expired ……..THE END

I am truly sorry that you have had such a bad experience using Breakaway One. Of the many, many copies sold around the world and working in real-life situations (including my two stations), no-one has come across such a situation as you describe, and that’s what makes it so hard to resolve.

It seems to be something unique to your particular hardware/software combination, and even then, it seems to have evolved, because it was working on your original hardware as I understand it, so only started to show this unusual behaviour when the equipment was replaced. This immediately points to something new in the hardware configuration that is contributing to the problem. Although the devices involved are ostensibly the same, we have no way of knowing if the actual componentry or device driver is identical.
For example, I have two “identical” dashcams in my motor vehicles, both from the same manufacturer, and with the same software revision, yet one behaves differently from the other.

Maybe the chipset that Leif used and recommended to you (and was obviously in the original configuration as well) has been superseded. Maybe an OS update on the PC you are using has replaced the original device driver with something generic. You need to go through each part of the broadcast chain to eliminate these sorts of possibilities.

As an aside regarding the forum software, there was some reason why Keith chose to drop the original forum software in favour of this system. I don’t know if it was just a great sales pitch, or whether there were licencing issues. Sadly, we will never know, but we must work with the tools we have been given.

thank you for your response and apology, it is a shame that it took 17 posts…
the os I am using is windows 10, and the servers I am using are all dell 1950s, the only difference between the machines is the speed of the processors, and the amount of ram, they are all using perc6 raid cards, and all use the same sound card,
originally the phase was out a little ie -5 to -7 when I changed the hardware it got a lot worse up to -20,
the next 2 machines I built had a phase drift of -10 to -15, it has never ever been 0,
after your response, I am now confident that you have 0 phase drift, so I am also able to achieve this, and that there is no adjustment or anything in the software that can affect the phase drift,
if I am reading your correct
the things that affect the phase drift are
Sound card
Drivers
Windows updates
MotherBoard
Hardware

NOT THE SOFTWARE SETTINGS

so based on this information, I will get a random pc install and try again,
I will figure it out when time allows me to

I have to say the responses I had from people who I think are admins were not good
I have supported breakaway by actively telling other people about it in the industry and buying it myself, and also trying things out to fix it myself before crying online
if a new update for a breakaway is bought out,
Charge more for it so the support can be given
attach the forum to the breakaway site ,
instructions are updated ,
and people who administrate actually talk like they would like to help I think things would greatly improve for the whole breakaway community
none of the above costs money “apart from leif building new software ”
Thank you milky for your clear suggestions
when time allows I will try different hardware because it bugs me when I can’t figure things out
have a good day and good luck
Cheers
