The AKD4619-A is an evaluation board designed to demonstrate the characteristics of AK4619, which
is 4ch 32-bit 192KHz audio CODEC. The control settings of this board may be controlled via USB port,
allowing for easy A/D and D/A evaluation. Analog 3.5mm stereo jacks are used for the input and output
of the analog signals. This board also has a digital interface which can be connected to the digital audio
system via optical or coaxial connector.
