Re: Fog machine remote controll, using a snake channel ?
1. I've done it, it didn't work because mic voltage is even lower than DMX voltage, and I had DMX noise in my mic channels.
Mic level is typically around 14 millivolts.
2. Back when I had my 120K rig I ran DMX through a 300' snake made of multicore mic cable (the other lines were fogger control, intercom, backups, etc.) and never had a problem. I probably wouldn't run movers that way these days, but simple DMX systems. Yes, the standard calls for 120 Ohm cable, but the signal is rather durable and can handle worse.
