The short answer is yes, but ONLY through the Sync input (and that's assuming that the Sync input/output is there for daisy chaining across the master bus, and not something else).
I ended up buying the Mackie Mix8 for this job. EQ on all channels, 2 Mic inputs, 2 stereo line inputs, very compact and good sound. There's lots of equivalents of this in even smaller packages if you google.
