audio inputs from the stage (ports 1‑8) for use in a monitor console or in a
recording or broadcast room.
All Cat‑5e network cables shown in the example diagrams can be up to 400
feet (120 meters) long. Fiber optic cable length will depend upon the type
of SFP device used (single‑ or multi‑mode). Always use the same type and
specification SFP transceivers in each MH10f.
MH10 Configuration Errors
Data Loops
When using multiple MH10/MH10f Merger Hubs in a digital network, never
connect a pair of ports (two cables) between MH10/MH10f devices other than
ports 9‑10 in Manual Mode Configuration C. Doing so will cause an A‑Net
data loop. Only Manual Mode, and its Configuration C specifically, can use a
pair of Cat‑5e or fiber cables connected between ports 9 and 10 in a backup/
redundant cable setup.
Changing from Manual Mode to Auto Mode
When changing from a Manual Mode setup using two MH10/MH10f Merger
Hubs in Configuration C to an Auto Mode setup, make sure that the backup/
redundant cable connected between port 9 or 10 on each MH10/MH10f is
disconnected before changing the network setup to avoid a data loop. Only
one cable (Cat‑5e or fiber) should be connected between ports 9‑10 when
the MH10/MH10f is being used in any configuration except Manual Mode
Configuration C.
