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.
