I don’t know whether it would work… I thought a while back that if I had to do this, I would try the Eartec wired Intercom adaptor (~$215). Eartec makes it to go from a wired intercom (RTS, Clearcom, Telex, etc) to the headphone jack of one of their wireless beltpacks (which use a single 2.5mm or 3.5mm plug headset plug (I’m not sure which)). I would guess that with a breakout adapter cable it would probably plug into the ATEM Camera Converter/Studio Converter.
