Working with the Allen & Heath DX Hub
Use the hub when the system needs several remote I/O locations rather than a single stagebox position. Start with a connection diagram showing the host, each expander and the audio paths between them.
Distribute I/O around the application
Group the required sources and destinations by physical location, then choose an expander arrangement for each branch. Check the supported cascade and channel mapping before allocating ports. The hub distributes audio connections; it does not increase the processing capacity of the mixer or matrix processor connected upstream.
Choose a supported host arrangement
Specify the correct host port or option card and verify the complete topology against the system guide. Redundant configurations require supported hardware and the appropriate arrangement; they are not a universal property of every hub installation. Document the intended operating mode so the cabling can be checked during commissioning.
