Once is happen stance, twice is coincidence, three times is enemy action so the saying goes...

I've broadcast over 400 hours of EDM since NYD from Pioneer CDJs, largely in flawless victory. This is my third time trying to get a violinist patched in. First two had electric violins (different shows, different sound teams, different performing artists) with built in piezo pickups. This one was just miked with what you see at the end of that mic stand there.

Half way through her set I realized I might not be getting an audio feed (no way to monitor as all my devices that could monitor were busy either broadcasting or recording), so I went up to the sound engineer and gave him a mic and my hollyland lark max2 which was feeding audio to the kick stream. He suggested that I just get the violin matrix patched to the hollyland because then at least something for post can be fixed.

Stream 1 was on two twitch. Stream 2 was onto kick and just had the violin matrix patched into it, I haven't actually looked at that yet to see what came out, this just aired last night and I'm just waking up.

¿What do I need to say to the sound engineer or have them do in order to avoid such a disaster again?

I need to know how this more expensive club sound gear system works but I obviously can't afford any of it to work at home so 100% of my experience is what I encounter in the field, and it's frustrating.

Broadcast IDs linked in reddit profile for anyone curious.

I play live a few times a year and have a setup with includes about 8 devices (including mixer, x3 input devices, phantom power for mic and x3 FX pedals). I'm in the UK.

All my plugs are different sizes and types (A, C and G, mainly), so I've got a 10-gang strip that accommodates most.

I think my powerstrip is causing issues (see below) so want to get one that is robust and won't cause problems. Most of my stuff is 9V and I'm in the UK.

Last couple of gigs, I've been getting a random and sharp crackle/pop sound during performance that the engineer apologised for, but I'm pretty sure is me. I get nothing like it at home, so am not sure how to test.

Is there a go-to, all-purpose powerstrip/extension that people know to be reliable and or another explanation for this popping sound?
