Two BOOMit can be connected through AUX / line in. If connected with another BOOMit the second one will replicate the output for double effect.

  • Connect the first BOOMit with a device through Bluetooth.
  • Insert the AUX cable in the first BOOMit.
  • Turn on the second BOOMit and press the “Source” button until Bluetooth/AUX led turns green.
  • Plug in AUX cable in second BOOMit, and turn up the volume to max.

This function allows you to connect up to four BOOMit together. First pair two BOOMit with Bluetooth, then connect each of those BOOMit to another set of BOOMit using the line in method described above.
