I only want to listen to 2 pairs at once not 4.
Also it's not like I would be monitoring with both pairs the whole time. It would be nice, however, to have both pairs playing at once every now and then.
I'm very serious about my monitoring, which is why I need a very specific tool.
The M-Patch 2 can do what I need but the reviews on it's poor build quality have kept me away unfortunately. I don't want something that's going to fall apart or not work properly.
Also SM Pro Audio has a new M-Patch V2 that looks even better. But not available yet
Anyway thanks for the insight.
