Nice! But it looks like those units use 1/4" inputs for the monitor signal...? I always get an XLR. Plus my signal is XLR from the DI at that point.
In general yes, but you can use a 1/4" to XLR adapter if need be for the monitor back from the FOH. Your DI can feed the rolls first and then pass through to FOH from the Mic Out, if I'm understanding you correctly.
But the PM351 may be a better option since it has a dedicated 1/4" instrument input and then the line and mic level inputs as well. May still need the 1/4" to XLR adapter, but it's cheap and easy.
