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
