Eigenschaften:

・ A high efficiency of 90% (10W + 10W output with 8Ω load), which is the highest grade in the industry and low heat-generation.
・ An output of 17W + 17W (12V, with 4Ω load) is allowed without an external heat radiator.
・ Driving a lowest rating load of 4Ω is allowed.
・ Pop noise upon turning power on/off and power interruption has been reduced.
・ High-quality audio muting is implemented by soft-switching technology.
・ An output power limiter function limits excessive output to speakers.
・ High-reliability design provided with built-in protection circuits against high temperatures, against VCC shorting and GND shorting, against reduced-voltage, and against applying DC voltage to speaker.
8) A master/slave function allowing synchronization of multiple devices reduces beat noises.
9) Adjustment of internal PWM sampling clock frequencies (250kHz to 400kHz) allows easy protective measures against unwanted radio emission to AM radio band.
10) A compact back-surface heat radiation type power package is employed.
