It accepts eight independent digital audio signal through its built-in I2S interface up to the sampling rate of as high as 192kHz, and it has four channels of auxiliary digital audio input, eight channels of auxiliary digital audio output, and five channels of auxiliary PWM output. Using external memory, professional quality sound field effects and loud-speaker location compensation can be implemented. Neofidelity's patent filed functional block called SFACS(Sampling Frequency Adaptive Coefficient Scaling) and world-unique floating point operation scheme eliminate audio performance degradation problems in conventional digital amplifier system.
