Our take
As an engineer, I appreciate the Opto 22 M4 RTU for its solid industrial-grade construction. It's a modular RTU that handles data acquisition reliably, though it's not a typical DJ controller. The price is reasonable for what it offers, but be aware it's meant for automation, not audio mixing. I found the setup requires some technical know-how, and the documentation is sparse. If you need a controller for fieldbus or remote I/O, this is a good deal. Just don't confuse it with a music gadget.
