IR-2: How do I turn the amp and cabinet on/off individually?

The BOSS IR-2 allows you to turn the amp and cabinet on/off individually.

See "Turning the amp or cabinet on/off" in the IR-2 Owner's Manual.

To use the IR-2 IR Loader app (macOS, Windows), see "Editing the system parameters" in the IR-2 IR Loader Owner's Manual.
