The indication content for LED LED turns on during each output is "H". LE1 Indicates unlock or parity error of S / PDIF. Connected to the ERF pin of DIR (AK4112B). (Normally off.) LE2 Indicates the validity status of S / PDIF. Connected to the V pin of DIR (AK4112B). (Normally off.) Toggle switch (SW1 on board) operation "H": AK4706 is Active. "L": AK4706 is Powered Down. (Note when the power of AKD4706-A is ON at first, SW1 should be switched from "L" to "H".)
