After unboxing, you can use Ground Central either as a standalone unit (via 9–12V power input) or by connecting it to your computer via USB-C.
In both cases, power must be supplied. Once powered on, the Current Preset Screen will appear after the initial splash screen.
Note: By default, your unit comes with the Audio XLR expansion card. We recommend to use a balanced TRS-to-XLR (or TRS to TRS) cable to connect the L or R output of the Ground Central to your audio interface or other gear.
