    No sound is output when three or more speakers are connected to a DJ device via a balanced connection (LINE 2)

    If you connect a DJ device to three or more speakers via a balanced connection (LINE 2), check the following:

    • Check the connection setup
      Audio received through the LINE 2 (BALANCED) terminal is passed unchanged to the LINE OUT terminal (pass-through). As shown in the diagram below, connect the LINE OUT terminal of one speaker to the LINE 2 (BALANCED) terminal of the next speaker in series.
