18 channel line mixer from MidiMan, who later became M-Audio!
You can see the 12 mono channels on the front, but there are also 3 stereo inputs in the back that are fixed to line level. Hence the "18" channels. But that doesn't count the L&R Aux Return. So, it really has 20 inputs!
This thing is built like a tank and nice and small. Nice for summing keyboards and drum machines.
Works great! No issues whatsoever. Comes with the power supply.
I have the manual, too, though it's not in the picture.
