We are running a S7000 FOH and C1500 at the monitor position with a DM64 mixrack.
All channels are duplicated and everything functions correctly with exception of one thing,
when vocal reverb is used on the monitor surface it changes the FOH setting.
There are separate send and return channels for each surface and the fx plugins seem to be routed to the respective channels.
Whenever you add vocals to the send channel on the monitor surface you get nothing in the monitor surface return, instead it is being sent to the FOH return.
any ideas?
