ProppFrexx ONAIR User-Forum

Hey guys,
this is my first post in here, but I hope to make a proper description of my problem. Because I cover live-events with my internetradio, Proppfrexx is mostly needed once a week.
First of all, when I bought my hardware and Proppfrexx in february, it all worked fine. But for a few weeks now, despite searching for solutions on the internet, there is a problem I can´t figure out. It is definitely not only a Proppfrexx problem, probably more a soundcard issue. Nevertheless I hope someone in here can help me.
Here are the symptoms:

• Every input accepts my adjustmens at first. when i open the options window of a single input again, it shows "channel 1".
• my first two channels are microphones, so they should be mono. after accepting my adjustmens "mono channel 1" (MIC1) and "mono channel 2" (MIC2) it shows "channel 1+2" (MIC1) and "channel 2+3" (MIC2)
• at the end, only one gives me a signal, though I here both on my headphones (which get there signal from an output of the soundcard)

This is a problem i do not only have with Proppfrexx, because i tested it with two other streaming softwares, winamp and butt, and tried to record it with audacity. Less possible options, but same outcome. Only one Mic gives me the full output it´s supposed to do.
So, important infos:

• Soundcard: Focusrite Scarlett 18i8, all drivers are updated, set back to factory default, no differences
• PC: changed from an older Vista-run laptop to a lenovo ultrabook with windows 10. way different capacitys, same result.
• proppfrexx: current update

I hope this helps you to understand my problem, if there is anything more you need, descriptions, screenshots etc., I´m happy to deliver. There are two screenshots attached of my inputs and ouputs.
Thanks!

A few questions:
Where did you connect your Mics (at the front or back panel)?

How did you configure the MIC1 and MIC2 Mixer Input Channels within ProppFrexx?
- Did you check the 'Mono' checkbox option for each mixer channel?
- and then selected 'channel 1' for the MIC1 resp. 'channel 2' for MIC2 as the "Channel Pair" option?
(note, that the description might still show 'channel 1 + channel 2', but if the 'Mono' checkbox is ticked, that first displayed channel is only used!)

Once configured, you might also want to make a right-click on each mixer chnnel name and then select the 'Standard Mono' - 'Processing' option from the context menu.

If all that doesn't help, I am afraid you need to ask Focusrite, if their ASIO driver really supports single mono input channel operations.
