Usually rca jacks run at -10db and xlr +4db, at least that how the interfaces used on my music computer and digital mixer work. I don't know any of the particular equipment you are using, but I'd look for an input setting on your interface that might adjust for the higher signal level.

I deleted my twelve year reddit account yesterday as soon as the Sync app gave the error. The day the internet died! Kinda bittersweet. I'm subscribing to a number of Lemmy communities that may develop into the type of places I used to hang out. I tend to lurk unless there is a thread subject on which I have some expertise and think a comment would add value. It is like starting over to find those specialized subject areas and posters here but I'm treating it like a new adventure. I never had a Twitter account but am also giving Mastodon a try too. Thanks for lemm.ee and the fediverse alternative!
Thanks for creating this instance! Reddit refugee here enjoying the discovery phase of what appears to be the new place. I was part of the digg migration to reddit over 11 years ago. The exodus from reddit to Lemmy feels similar. Using Jerboa for Android: so far so good.
I'm just guessing that it might be the -10 vs +4 level issue regarding your equipment setup. You could try putting a 10 to 20 db pad inline on the xlr input path to solve the issue: https://www.amazon.com/PROCRAFT-INLINE-ATTENUATOR-FEMALE-ADAPTOR/dp/B07B1G6PM8/ref=mp_s_a_1_4?crid=3W1VFFZ0Q65TK&keywords=xlr+pad&qid=1689794883&sprefix=xlr+pad%2Caps%2C118&sr=8-4 It's all about gain staging. Here is a link to a 7-page Gearspace thread about it: https://gearspace.com/board/audio-student-engineering-production-question-zone/566766-4db-10db-what-does-all-mean-exactly.html Somewhere in the thread someone says: "Actually, I learned later that a simple XLR to 1/4" TRS cable going into my interface line inputs solved the too much gain issue"
