  2. DAC-RaspberryPi power supply connection terminalWhen supplying DAC power from the GPIO pin of RaspberryPi, short this pins. (Default)When connecting separate power supplies from the external power connector to the DAC and RaspberryPi You must leave this terminal open.
    Terminal description
    1 RaspberryPi +5V
    2 DAC +5V

    Connector : MIL 2pin

  3. LCD powerThis connector can supply 5V power to LCDs for RaspberryPi. This connector is connected to the 5V terminal of RaspberryPi GPIO.Notice: The connector is not mounted, so you should solder the connector yourself.

    [B] Balance terminal
    Connector : MIL 8pin

    Notice: Balance terminal is not mounted. If you want to use you need to solder it.

  5. DAC output terminalThis is for outputting a signal from the DAC output terminal. You can connect your original amplifier instead of the onboard amplifier.You can use a line transformer instead of an amplifier. DAC out to AMPin

  7. Operation panel terminal
    1. SW1:SRC operation mode setting pin
      • OFF:Automatic setting mode(Default)
      • ON:The SRC operating mode follows the SW2 setting.
    2. SW2:Switch the SRC output manually.
      • OFF:Output in PCM regardless of the input format.
      • ON:Output in DSD regardless of the input format.
    3. LED
