¡Þ Use
¡Ü As a 270-Watt digital power amplifier for storewide announcement, in time of a stoppage of electricity supply, it works after automatically transferring to battery power without separate device by being attached a DC24V input terminal so that it is suitable for emergency announcement for industry.
¡Þ Function
¡Ü As a 1U RACK attach-type, this realized 270-Watt high output in a small space.
¡ÜThis is light because it applies AC/DC Dual SPMS technology without using output or power trans.
¡ÜThis realized high efficiency with PWM-method digital amplification.
¡ÜThis has a DC24V input terminal attached so that it can work with outer battery power in time of a stoppage of electricity supply, which is essential to emergency amplifier.
¡ÜAs this has a built-in perfect protecting circuit, it is designed appropriately for amplifiers for industry, improving reliability. (Has built-in automatic correction circuit such as output short, overheating and over-current)
¡ÜThis obtained KT mark from the Ministry of Science and Technology, CE and EK.
