NODE Players* can transfer digital audio (USB Audio 2.0) to an external DAC via the USB Type-A slot.

*The following NODE Players are compatible with USB Audio OUT:

  • NODE ICON
  • NODE (N132)
  • NODE NANO
  • NODE X
    • NODE (N130)

    When connecting an external DAC to the USB port of NODE Players*, the USB port is automatically enabled.

    Note: When the USB port is enabled, other audio outputs (Analog/COAX/Optical) are disabled.

    To manually enable the USB port, perform the following steps:

  • Connect a compatible external DAC to the USB port of NODE Players*.
  • In the BluOS Controller App, select Player Drawer .
  • Select the context menu (3 dots) of the required NODE Players*.
  • Select Audio Settings .
  • Select the external DAC from Select output .

    • To disable the USB port (without unplugging the external DAC) and enable other audio outputs (Analog/COAX/Optical), set the Select output to Default in the Audio Settings screen of NODE Players*.

    Note: If you encounter issues with USB Audio OUT to an external DAC, refer to our Help Center article .

    USB DAC - ROON

    If you are using ROON and MQA with an external DAC, sending digital audio through the USB port of NODE Players* may cause audio dropouts. In ROON, please adjust your NODE settings using the following configurations:

  • Go to ROON's Device Setup screen for NODE.
  • From the MQA capabilities drop-down, select Renderer only .
  • Expand Show advanced and set the Enable MQA core decoder to Yes .

    If you still encounter audio dropouts, use USB DAC implementation natively without ROON and reach out to ROON directly for further assistance.

    Notes

  • The headphone (3.5/6.3 mm) connected to NODE Players* has precedence over USB Audio out, thereby muting the digital audio output from USB. NODE NANO does not have a Headphone jack.
