Help for live streaming with mixer

[Espo_17]

Hi I am the “computer guy” of a little church in italy (50 people), for almost 3 months we have been live streaming but we are willing to upgrade the audio equipment because now we are using my phone and the webcam as microphones.

Our idea is to buy:
a mixer (mackie profx10v3) ProFX10v3 - PROFXV3 Series - Mixers - MACKIE 1
a wireless headset microphone (eikon WM300H) https://www.eikon-audio.com/en/prodotto/wm300h-uhf-wireless-belt-pack-microphone-system/
and a pair of speakers for the people in the back of the room to hear well.

now the problem is:
i want the drum and the guitar to go into the mixer and be sent to the back speakers so that people in the back can hear the music too and sing at the right beat.
i would plug the mixer in my pc too to use it as surce for my live stream but at this poin the people connected would only hear the instruments because we do not have a singer, instead all the church sings along.

my idea was to buy a cheap chorus microphone to be positioned on the cieling, facing the audience so that it could send the voice signal to the live stream but doing this the singing would be heard from the speakers too creating a bad effect.

i do not know how to solve this problem, if someone of you would help i would be very gratefoul.
also sorry if i wrote something wrong but the i do not know evry “technical” word in english, feel free to correct me and ask for more explenations

you can try an feedback distroyer but mics in front of speakers is a Hard thing this is why the speakers stand in front of a band !

better is to buy 2-4 good mics and make audience mix and send this to the stream ! with an auy out on the mixer you can send the signal from the speaker mic too

A word of caution. I'm not familiar with Mackie, so not sure if this applies. Many Digital Audio Workstation software, due to issues with how Windows Audio (WDM) works do NOT direct audio out to Windows Audio sub-system, which can cause issues with getting audio into OBS. For other DAWs, I'm aware of work-arounds, but they are 'kludgey' in my opinion (I'm of the keep it simple mindset, and adding extra audio routing 'hops' only creates additional points of failure, in my opinion, but sometimes you do what you have to.

Then, as for not having a cantor/singer and using an audience mic instead .... yea, what @cyclemat said.
Our situation is that we do have a choir and pipe organ in the back of the Sanctuary. To pick them up, we added a Shure VP88 mic up in the choir loft area... but they are behind the Main speakers. That VP88 mic is NOT amplified in-house, but livestream folks will hear an echo during quieter portions of stream (ie sermon). The fix for this would be to manually Mute the choir mic when organ/choir not active. But who will do that?
- IF you have a 'sound engineer' manning the mixer board every service, that person could do it
- Or will the person running OBS do the audio adjustment/mixing? if this (which is what we will eventually get to.. hopefully, then you need to consider screen real estate. We have a dual monitor setup, as we also have PTZ camera controls to deal with. gets busy for single OBS operator)
oh, and be aware that as you get into the audio, it is common/desirable to have a slightly different audio 'mix' {settings} for in-person vs livestream audience.

how do you get your vp88 to not be amplified in house but only in the stream with only 1 mixer? cause i want only one of the 4/5 sources of the mixer to be muted in house but heard in the stream...

for the rest i am the only one running obs and mixing so i will get even more multitasking

already thanks for the uppergiven answers

At the moment, our audio mixer is connected to the OBS PC using an analog connection (1.8" connectors to gain adapter, to with adapter cable to 3.5mm TRRS) from a sub-channel output on the mixer. As such, we only get a single, combined audio signal from the mixer. In our case, we have the Presonus AR12 USB, which has a Main mix output, and a Sub(Aux)-mix. We are using the Sub-output to the OBS PC
So for in-house (Main) output (to amplifies/speakers) the gain/volume is set to 0 for the two VP88 (stereo) channels, with normal gain/volume, etc set for the Sub/Aux mix output
Further the mixer and OBS PC are in a sound closet downstairs. Keyboard, mouse and monitors are upstairs (50ft fiber optic DisplayPort MST cable and powered USB cable for keyboard & mouse). Today, someone would have to stand by Sound Closet and adjust manually/physically on mixer (which isn't going to happen). Fortunately, the echo currently isn't good, but not terrible
*if* I was using a digital connection from mixer to PC, such that I had access to each mixer channel individually, then I'd be able to selectively Mute channels for livestream only.

For the Mackie, looks like the ProFX12v3 has sub-groups, and the front panel image of that model is similar my Presonus with Aux adjustment dials per channel. But, you may be able to set digital out on ProFX10 to PC, use Mackie's DAW (audio software) to send full mix to livestream audience, but mute certain mic(s) with return signal back to mixer, which then goes out to speakers? Sounds possible, but what exactly that would take would be specific you that mixer and your setup. Audio is NOT my area, so for me, being able to get away (make due) with analog sub-mix since we resume in-person worship last summer has been a blessing

To add to the prior message in regards to digital Audio connection from mixer to OBS PC
- Many mixers and associated software presume sending signal to PC, processing in DAW software (effects, filters, etc) and then sending audio signal back to mixer and then out to amp/speakers
- in my case, I'd like access to each channel such that I could selectively mute channel(s) going out to livestream. Though it might be nice to be able to adjust in-person audio from the OBS PC console (ie, take Main out from mixer, adjust on PC, and send back to mixer), that isn't a current desire/expectation/need (but as I think about it, probably a nice to have option even if it does make multi-tasking even worse/more complicated).
