To get the ONE for iPad & Mac back to the state it was in when first taken out of the box:

  1. Hold the Encoder knob down
  2. Unplug the USB cable then plug it back in
  3. Keep holding knob down until all white Icons flash 3 Times then goes steady showing the Speaker.

If you hold too long the Speaker Output will be come Muted, simply click in the Encoder Knob again and Un Mute the Output

Note: There is no Reset All for the original One from Apogee
