Features

・High efficiency and low heat generation eliminates external heat-sinks
・Eliminates pop noise generated when the power supply goes on / off, or when the power supply is suddenly shut off
・High quality muting performance is realized by using the soft-switching technology
・The output power limitation function that an excessive output can be limited is installed
・With built-in protection circuit that detects DC voltage impression to speaker
・Incorporates a master / slave function that enables synchronous operation when several units are used simultaneously
・Allows the internal PWM sampling clock frequency to be adjusted
