NPA series is AC/DC digital power amplifier which cutting-edge technology is applied for compact and light hardware and high
impedance output(70V/100V). Especially, it is optimized for effective control and operation by combining state-of-art hardware and
intellegent control software and features extraordinary performance and differentiated functions. Also, its self-diagnosis function prevents
serious fualts with inspection of amplifier errors.
