MATRIX 1.4 - OUTPUT PROTECTOR PROJECT


FEATURE NOTES:

This output protection system is built-in both of SHORT-CIRCUIT PROTECTOR & LOUDSPEAKER PROTECTOR. The SHORT-CIRCUIT PROTECTOR will work only to break the output connection if output is short-circuited or overloaded by the non-proper loudspeaker impedance. The LOUDSPEAKER PROTECTOR will work only to break the output connection if the FAULT OFFSET being detected. The LOUDSPEAKER PROTECTOR designed to be able to recognize between the actual signal over the DC OFFSET, so that protection will not occur if the output is loaded by the actual audio signal though in a high level amplification session.
