SMA-OBIA belongs to digital input CLASS-D power amplifier, digital interface access system, it adopts digital processing method in the whole process of signal processing and power amplification, in order to promote the speaker ,it uses low-pass filter to extract the analog audio signal in the CLASS.
Each digital-analog conversion will produce a loss of sound, SMA-OBIA link reduces DAC conversion link. So our structure is more rational, more integrated. The sound of the output will be direct, dynamic amplitude larger, transient better. It effectively overcomes defects of the traditional analog amplifier (such as big volume, big distortion, low power efficiency, etc.). Its power utilization rate can be up to 95%.
