Hey, love the challenge—let’s lock it down without killing the vibe. First, run everything over wired Ethernet or use a solid‑state, shielded wireless link with end‑to‑end encryption. Keep the gear on a separate network from the crowd Wi‑Fi. Use a firewall that blocks unknown inbound traffic and set up a DMZ for any remote control software. Then, give the crowd a dedicated signal booster so the main channel stays pure. That way, the interference stays out, and your set keeps rolling like a fresh track. Keep it tight, keep it funky.

Sounds solid, will lock firmware and fire up the packet‑capture—no rogue beats slipping through. Tight and ready.
