Monoprice does occasionally have "b-stock" and "open box" sales; but this is not one of them.
Puts up some pretty good specs on the bench:

The rz30 only puts out 36 watts per channel into a 4 ohm speaker.
The Monolith puts 135 watts per channel into a 4 ohm speaker.
All those extra watts gives you lots of clean headroom for big dynamic swings.

4 ohm stable/ capable and XLR connections as well
Yes, you will have to enter all your info again, but it's less frustrating than being caught in a loop.

Post the exact mixer you have if you need specific instructions.

And how many thousands of dollars is an amp with fully dual differential balanced XLR connections?
And you are that concerned you are certainly not going to use any RCA inputs either...for any reason

So they are selling used products with full manufacturer 3 year warranties?
