Block Diagram
This diagram shows the essential features of the U-Hub, highlighting how the audio feed from the rear panel inputs is combined
onto three of the U-Net connections.
U-Net is run as a redundant loop, all U-Net enabled products have two ports. Port 1 on the U-Hub would be connected to port 1
on the first device, port 2 on this device would link out to the next device and so on with a final link back to port 2 on the U-Hub
to complete the loop. This allows the system to continue working seamlessly in the event of a cable being damaged or
inadvertently disconnected. Data will simply flow in the opposite direction to allow continuous communication.
Audio connections are combined with the network feeds. Audio input 1 is connected to a pair of spare connections in the U-Net
port 1 ODU. This would usually be used as the “send” to the first array. A return from the array would be connected to the first
link in connection. Audio 2 is combined with the second ODU in the linked pair allowing audio to be fed to a second array, a side
hang for example. The network return from this array comes back to the second link in. Audio 3 is connected to the link out of
this pair and can be used to route out to a third array such as the sub-woofer stack. Finally, the U-Net return from the subs is
connected to U-Net port 2 on the U-Hub to complete the loop.
System Example
This diagram illustrates the wiring to the array for a system as described above (note that mains connections have been omitted
for clarity); -
