Hardware Issue Question

[siffland]

I just got my Caribou Lite (6GHZ R2.8) from mouser. I am having issues getting it working. I just want to verify that there should be no components soldered in the "MXR IN" box on the top of the unit and nothing soldered in on the MIXER part of the unit on the bottom (All picture I see have these fully populated). I know it went through a lot of hardware revisions.

I am probably just not setting up the software correctly but want to make sure I am not chasing my tail and just didn't get an unfinished piece of hardware.

Thanks, Sean
