U‐Hub
Audio input can be direct from a console or from a DX4.0 processor used as a matrix. Three audio feeds – each either balanced
analogue or AES EBU digital‐ are connected to the three audio inputs on the rear of the U‐Hub.
The first of these is combined onto the U‐Net Port 1 which is connected to the first cabinet of the main array via a PWAXXXXX U‐
Net to U‐Net + Audio adaptor which splits the feed from the U‐Net cable to a U‐Net only cable and an AES spec audio cable
terminated in a standard 3‐pin XLR. The XLR is connected to the audio input. The audio is daisy chained between cabinets using
standard audio link cables.
When the final network cable is routed back to the U‐Hub it is terminated using the first of the link pairs. The link pairs link the
network connections (first two twisted pairs) but NOT the audio meaning that the link out can be used to route a completely
independent audio feed connected to the Audio 2 input up to the side hang in the same way.
The return from the side hang goes to the second link pair input with the output also carrying audio input 3 to feed the sub array.
Finally, the last network connection goes from the final sub back to port 2 on the U‐Hub to close the U‐Net loop.
