The class-d headphon driver
is a high efficiency class-d,
studio-grade audio driver.
Ultra-fast FPGA audio calculator
connect the driver direct with the ADC,
USB-input and digital-input.
The low noise modulation-technology requires the headphon as
reconstruction-filter (LC). This scheme
provides high efficiency
even at low output power.
This direct coupling makes the quality
of the headphone audible.
