Duomike,
My understanding is this correction device is very clever & flexible. Not only can it split the signal 8 ways & send to its various analogue or digital outs, but what is useful in this situation is it can also do all the splits for the xover internally & send that split & corrected digital information bussed to the main out. (so my system stays plugged in the same way. Only difference is a digi out into correction, then digi out from correction back into my DAC)
Im not sure exactly what happens with the microphone & room responses. I suspect you do them 1st. Then set the xover freqencies or types for each driver and it works out the rest & busses it to the main output.
Now this is probably not the best way of using it, but it is the most practical for my purpose, without the need for multiple amps etc etc.
But as they say "the proof of the pudding is in the eating". I will let you know but the guy is extremely confident it will work as I explained. I know one guy who has used it & he said it was perfect! I had that RP1 room correction device which is not as flexible, but it was very very good.
