Among the features, its superior efficiency and AC load detection) performance coming from the internal exclusive Full fault protection structure, makes it the most suitable device to DC offset detection simplify the thermal management in high power sets. Four independent short circuit protection The dissipated output power under average listening condition is in fact reduced up to 50 % Clipping detector pin with selectable threshold when compared to the level provided by (2 % / 10 %) conventional class AB solutions. Standby/mute pin This device is equipped with a full diagnostics Linear thermal shutdown with multiple thermal array that communicates the status of each warning 2 speaker through the I C bus.
