Hi Moses, your question is a bit more complex than it sounds……while you can assign different parameters to the PL10 these are limited to the following
Unused
LED on/off
Mute
Fader up/down
Send level up/down
FX level up/down
PAFL
Scene recall
Custom MIDI string
Talkback assign (according to the pdf ) :
so not all 48 ch parameters and not all at one time ……and, to preserve separate mon and foh you would technically have to divide the inputs between all available channels so that you’d end up with, for example, drums input ch 1-8 for foh and routed to mix and then assign the drums also to ch 24-32 for mon routed to auxes or other…bass ch 9 for foh and ch 33 for mon etc….that would preserve any EQ limiter etc. you make at foh so on a 48 channel rack you could possibly do a 24 ch full mon and foh (I’m not including surface inputs though you could). However there is the inpracticality of having so many channels assigned to a PL device as there is no way for the Worship Leader to know what he/she is controlling unless you write a description on the PL and for 48 ch that would be daunting to keep up with! there are most likely other ways to do this ……you could assign the PL switches to scenes which would recall certain configurations and you could send/pre mixed inputs through auxes or others means and give him/her access to the aux mix levels etc…..or even assign some important channels to the pl remote ……..there is a pdf on using theses as well as other types of PL here:https://www.allen-heath.co.uk/uk/DisplayProduct.asp?pview=50 hope that you will find a solution for your needs.
