„ Set up Jumper pins
JP1 (RX): Selection of Optical connector or BNC connector
TORX176 (Default): Biphase signal is supplied to AK4112B by optical connector.
COAX
: Biphase signal is supplied to AK4112B by BNC connector.
JP2 (GND): Separate/Connect AGND and DGND
Open
: Separate AGND and DGND.
Short (Default) : Connect AGND and DGND.
„ The indication content for LED
[LE1] (ERF) : AK4112B unlock and parity error output.
[LE2] (FS96) : AK4112B 96kHz sampling detect.
[LE3] (AUTO): AK4112B AC-3/MPEG detects.
