The ST2 (Stereo 2) input …can I put a keyboard in this input by-passing the USB for live
If yes is they’re a volume control for ST2?
according to the photo it looks strange doesnt say Mix to St2
Page 3 of the manual [ https://www.allen-heath.com/media/AP10147_1-ZEDi-10FX_User-Guide_A5.pdf ] at the bottom of that page is a volume knob for ST2
It looks like it overrides the incoming USB 1 & 2.
