Digital distortion is quite different, as illustrated by this simplified example. If we take the situation where a 4
bit word has the positive maximum value of 0111, and add to it the smallest possible value of 0001 (in other
words, the smallest increase in amplitude possible), the addition of the two results in 1000 - the value of the
“negative” maximum. The value is turned on its head, going instantly from positive max to negative max,
resulting in the very noticeable onset of extreme signal distortion.
5. INSTALLATION
Your BEHRINGER FEEDBACK DESTROYER PRO was carefully packed in the factory and the packaging

remove the ground connection within the units or at the supply, or fail to make this connection
at all.
Before you switch on the unit, check that it is configured to match your AC mains voltage requirements. If it
