Case Development Audio Equipment Field

Digital Power Amplifier Module

Our founding opportunity was the analog / digital compound amplifier in audio equipment.
This products by advanced technology is only one it in the world that take advantage of Transformer Coil and Resonant Switching technology.
it’s very low copper loss resistance by high frequency transformer

  • it’s extremely low copper resistance by high frequency transformer.
  • it’s extremely low noise generation by switching at 0 voltage and 0 current.
  • it’s low switching loss (low fever = high efficiency)

Also, this inverter technology developed to commercialization of DC / AC inverter (DA-1000B).
