Sound Issues with live recording

Hi! Hope someone can help.

I have absolutely zero experience with recording beyond pushing record and stop. Hubby has a growing Facebook Live show where we interview musicians, comedians about life and what they are doing professionally. We’re trying to move expand to a podcast and only seem to get decent sound when we record straight to an Apple device.

We’ve partnered with a local bar to record on their stage and have permissions to use their sound system and wifi. I’m attempting to plug into the main soundboard. I’m running a line from the soundboard’s “phones” jack (the live sound is great, but I’ve heard better - I don’t know enough to fix it :confused: ) with a standard guitar/sound type cable into a mini analog board (Behringer XENYX502 - again, I know nothing about what to do with all the knobs - just plug the line in and line out and hope it works). Then I have an RCA to USB cable to run the sound into my computer running Audacity 2.3.3 on Windows 10. (I’ve downloaded the update and will install it before trying again.)

The artists are able to be heard through the bar’s soundsystem just fine, but I’m only able to hear the redlined sound in Audacity and it’s very tinny. I’ve attached an audio clip in case this helps.

Any ideas on how to improve my sound? We’re running on a negative budget so I really can’t afford to purchase any new equipment. We’d love to have a better, more professional sound than we get from setting an iPhone or iPad between the artists or on a table in front of the stage and recording with the voice recorder app that comes pre-installed.

That distortion could be Windows audio enhancements.
You need to turn those enhancements off, (in both the recording & playback tabs),
