PM–4 guide.
a sample guide for a sample product. on okaybravo, a maker links guides like this one from the product page.
1. charge it. plug in usb-c until the screen shows a full battery.
2. plug in. up to four stereo sources go into the 3.5 mm inputs on the top edge.
3. mix. black knobs are gain, orange are filter, white are effect send. the big knob changes the effect.
4. the control app isn't real either: demo works is a demo company.
