exaU2I is the missing link between a PC and the I2S input of your DAC. It is designed for use in high-end DIY audio projects aiming to achieve sonic performance that rivals traditional audiophile grade gear.

Asynchronous operation is achieved by using fast FPGA control core, 256 kB FIFO memory buffer and proprietary ASIO driver.

The ASIO driver provides automatic sampling rate switching and bit-perfect data transfer.

Galvanic isolation of the I2S output from the FPGA core and the USB ground virtually eliminates jitter and common noise originated by the PC.
