U‐Hub
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); ‐
