The Fubar II and Fubar III USB DAC’s have a few different operating modes you’ll see once they are powered ON. You can tell what mode the unit is in by observing the indicator lights.

But first off, lets define the lights on each unit and cover off a few distinctions between the Fubar II and III.

The Fubar II has three lights: Power (blue), Suspend (red) and Playback (green).

The Fubar III has only two lights; Power (blue) and a Combination Suspend (red) / Playback (green)

Here are the different modes you’ll observe while using the Fubars

Mode 1
The PLAYBACK light is ON: This indicates there is a signal from the computer and information is being transferred. (eg. you’re playing a song) this is my favorite mode by far!

Mode 2
The SUSPEND light is ON: This indicates there is no connection detected from your computer. The Suspend light will come on when your computer goes to sleep. The light also comes on if the USB cable comes disconnected when the unit is powered on.

Mode 3
Both the SUSPEND and PLAYBACK lights are OFF:  This indicates a good connection to the computer but no information is being transferred. You may occasionally see the playback light “flash” as a computer sound or other bit of information is sent to the Fubar. You’ll also hear the same sound from your speakers if your amplifier is turned on.

Hope this helps clear up any mystery surrounding the Fubars and their indicator lights
