1) No, it says the *console* is digital. The snakes may be analogue or digital but nowhere in the source text does it say that. If they are digital, they don't need isolating transformers but it may be that the rider means "if analogue, must have transformers". 2) 3-way as in 3 destinations. The on-stage mic. signals are sent to 3 places. One is FOH, one is the monitor console and the third is this diffuseur, whatever it is. I'm still holding out for a broadcast truck. 3) The stage box contains the transformers, one per channel. They are used to split the mic signals to the various destinations. The FOH feed may well be direct with transformers (or one multi-winding transformer) on the other feed(s). The transformers are there to isolate the console inputs from each other. With a hard-wired (no transformers) snake, the two (or more, 3 in this case) inputs are effectively wired in parallel and adjusting the trim pot. on one console can reduce/increase the signal to the other leading to the monitor and FOH engineers messing up each other's mixes. In practice, with modern consoles, this is not as big an issue as you might think, the trim pots get set during sound check. |
