Hi Nicola,
yes dual operator use.
Big orchestra plus rock band
Or big orchestra plus lots of head microphones plus choir etc.
Also, please have a look on the other parts of the original questions please 🙂
For example it would be important to have insert point after the pre fader aux send, but still before the fader – monitor mix using vocal rider inserted for a channel going to all other band members (post fader aux send), but for himself without vocal rider (pre fader aux send)
Thanks,
