3.3 Auto Standby
This pushbutton turns ON or OFF the auto standby function. By default this control is set to ON.
When ON the speaker will automatically turn into low power mode when no audio is fed to the input for longer
than the time that is set on the control software, which by default is 60 min.
As soon as the audio comes back the speaker will turns fully on.
When the speaker goes into standby mode the front LED will DIM its brightness with respect to the normal
condition.
3.4 CAL/Preset
This pushbutton allows you to cycle between DESK filter, FLAT (default) and custom user calibration (if present).
The Desktop filter sets an attenuation filter to compensate for the typical acoustic effect of a console or a desk.
Such placement usually results in a boost in the lower midrange.
By holding this button for three seconds the speaker will start the ARC calibration process (the ARC calibration
process can be also launched by the control software).
To perform a custom calibration refer to the next chapter (4. ARC calibration).
IMPORTANT: units shipped from our factory have no custom calibration loaded, so the CAL position won't be
available until a custom calibration has been performed by the user.
Once the ARC calibration has been completed this pushbutton controls the switch between FLAT, DESK and
CAL settings, by cycling among the three in this sequence:
FLAT -> CAL -> DESK -> FLAT -> ...
