This is an example of how to connect the devices when you want to use your tablet or smartphone to have a voice chat while listening to the sound of the game.


  • To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any connections.
  • Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.


  1. Connect your mic, headphones or other external equipment to this unit.

  2. Use a USB cable to connect your iPad or iPhone to the USB port.

    • When connecting an iPad/iPhone that uses USB Type-C®, use the included USB cable (the cable without the POWER tag).

    • When connecting to an iPad/iPhone that has a Lightning connector, use a Lightning to USB 3 Camera Adapter, available separately. When connecting the Lightning to USB 3 Camera Adapter to the BRIDGE CAST X, use a USB Type-C®  to USB A cable (commercially available).

    • We recommend the use of Apple genuine products.

    When you want to import video along with audio, connect to the HDMI IN 1 or HDMI IN 2 connector with an HDMI adapter cable (commercially available).

  3. Set the USB I or USB II connection settings switch to “MOBILE” or “CONSOLE/MOBILE”, depending on which USB port you’re using.

  4. Turn on your external equipment.

  5. Adjust the volume on this unit to ensure a listenable volume balance while testing the sound from the game app (iPad/iPhone), voice chat and mic.
