A little unit to listen to your rack or an individual module on the go. Use headphones, or listen to the little speaker it has on board. Handy when you’re setting up for a show, listen to things before you’ve got your whole rig set up.
Mostly surface mount already installed, and the rest is pretty simple to put together, I couldn’t find a build guide, but again, it’s pretty straightforward.

One thing to note: During the demo I found that when you drive the speaker with the volume knob more than 2/3s up the power draw rises from 10-28 milliamps up to a max of a whopping 280 milliamps, which could be a problem if you’re on a tight power budget, just don’t turn it up too much. Headphone does NOT do that, it’s a safe 10-28 mAmp all the way around the dial.
