8.5.2.1 Panel Overview
Figure 13:Panel overview - Audio mode
When the BOS1901-KIT board is in Audio mode, it is detected by Windows as a speaker device. When
this device is selected, all audio output from the PC will be sent to the board. Make sure to deselect the
Boreas DevKit to avoid the PC from playing system sounds on the actuator.

User should use a software that can specifically select an individual USB device as audio output. For
example, Audacity® allows to easily create and play waveforms on the piezo actuators attached to the
board. See appendix for more details.
8.5.2.2 Audio Limiting
Because some piezo actuators have voltage operating ranges that are smaller than the capacity of the
BOS1901, the BOS1901-KIT board has the capacity to limit the voltage range of the audio signal in order
to protect the actuator.
Using the factory default values, the BOS1901-KIT board will limit the output voltage between -10 V
and 60 V. This range is within tolerances of all piezo actuators model supplied in the BOS1901-KIT.
