Passthru/Monitor Out to OBS

[awamy]

So I think this is a very noob question but I've a student activity event in my university that I want to stream and the University provided us with a venue that has JBL EON one Pro Speaker that they use it as a mixer.
it has two output options (see attached photo 1,2) :
1 x Dual RCA Stereo (monitor out), 1 x XLR (pass thru)

what I need to do is to get the audio from the JBL EON as an OBS audio input, what do I need to do that ?

I found this Cabel as well (See Attached photo 3) which is RCA to 3.5 would it work if I bought it and connected it from the JBL Monitor out to my 3.5 in my laptop? or do I still need an interface?

Using a professional interface is strongly advised, even if you use unknown/foreign equipment for this eve!

Contact a dry hire provider to loan a good one (test the day before) and a passive di-box. They will provide you with the right cables (at least two), too. You can go with the monitor out, if you want, because it has a pot at least. You don't need to go for stereo if you have only one of these boxes. (Otherwise the pass-thru is often needed to route the signal to the second box, then you must use the monitoring output.)

The JBL box will be ground earthed, and your streaming machine too. Thats why i strongly recommend to have a di-box at hand. Otherweise you could ruin that eve for yourself with loud hum and noise.

If you strictly want to go stereo, then you must use the monitor out and borrow a stereo di-box. The supplier will help you with cabling in this case, too. Do not use a direct sound-in to the streaming computer if you aren't absolutely sure what you do!

The problem is that I have no provider with no budget as well , all I can afford is get that cable (RCA to 3.5) and use it to connect the JBL Box from the Monitor out slot to my streaming machine (Laptop) and then add it like any input audio to obs.
the other option is not streaming the event at all.
it's a student activity and I'm still an intern and doing that for the experience itself so I don't know what should I do.
is connecting the JBL box to the laptop using RCA cable to 3.5 can damage the JBL Box or the laptop?

"You can't have your cake and eat it too."

Can you test the equipment before? But be warned. Meanwhile there are dozens of standards for jacks on laptops: 3way (trs), 4way (trrs), line in, line out, mic w/o power, mic w/ power, headset,... (sometimes all-in-one jacks dynamically managed) The likeliness is higher for bricking the laptops mic power than that for bricking the monitor out of the jbl box. No more than that in general can be said in advance.

So i have only one hint for you: Take the monitoring pot all way down and raise it slowly and carefully while monitoring (earphones!) and looking for the audio mixers meters in obs, while having a calm test music signal on the jbl box. Beware of hum and noise. If you encounter alot of them (or any other kind of upcoming issues), pull out the cable as fast as u can. Disclaimer: Its the absolutely unprofessional way to do...

By the way: If you are n intern, the faculty should be able to provide you with a small handful of bucks, at least. :/
Is there an staff technician you may consult regarding their equipment? What kind of university is this, if they wouldn't have audio interfaces (as mentioned above) to lend, at least since the beginning of the pandemic?!??!!

The technicians of the biggest lecture hall at university often have a bit more stuff at hand, maybe a di-box, too.
