IMPORTANT INFORMATION 

The freeDSP-aurora board might generate signals that may damage your audio equipment. 
Please read and understand this manual before starting to work with your board. Adjust all 
hardware settings and configure your software before connecting any audio equipment to 
freeDSP-aurora. Always start with low volume on your amplifier and slowly increase the level 
to reduce the risk of damaging your audio system. 

Especially the installation of alpha and beta versions can lead to incorrect behavior. The 
installation is at your own risk.
