Protection
DSi-Series amplifiers are protected against
shorted, open or mismatched loads;
overloaded power supplies; excessive
temperature; chain destruction phenomena;
excessive output current, and input overload
damage. They also protect loudspeakers
from input/output DC, large or dangerous DC
offsets and turn-on/turn-off transients
