To route an incoming AES/EBU two-channel signal to another speaker, use an cable with XLR plugs on both ends to connect the AES/EBU OUT of the first speaker to the AES/EBU IN of the second speaker.

To route an incoming S/PDIF two-channel signal to another speaker, use a cable with phono plugs on both ends to connect the S/PDIF OUT of the first speaker to the S/PDIF IN of the second speaker.
