8. MLA Compact Combined with CSX‐Live 218
In this example the CSX‐Live 218 subs have been deployed with an MLA Compact system as a lower cost alternative to the DSX
or MLX subwoofer. Much of the infrastructure is based around the standard MLA compact system components.
Analogue audio is routed from the mixing console to left and right first connected to the CSX‐Live 218 Subs linking between each
sub using the parallel output XLR before linking up to the MLA Compact array and using short XLR links between each MLA
Compact Cabinet. It would of course be perfectly acceptable to send an independent sub feed from the console which is a
common practice.
A Master and Slave rack are used for U‐Net connection to all MLA Compact cabinets. The advantage of an MLA Master Rack is
that it features an Ethernet Switch used to network the Merlin Processors in all racks and the same switch can be used to link
the CSX‐Live 218 subs. The MLA rack patch panels bring the Ethernet connection out on the rugged and IP68 rated ODU
connectors. One ODU Cable is required to link Ethernet between the two racks. Some adaptor cables are required to go from the
ODU connectors to the EtherCon connections on the CSX‐Live 218s. The diagram shows two such cables one going to the left sub
array and one to the right. It would however be perfectly reasonable to use a single adaptor to the right array and then use
EtherCon to EtherCon cables to link the CSX‐Live 218 on one side before using a long EtherCon cable to cross the stage to the left
array with a further link cable to join the two subs on that side. This is a perfectly acceptable solution for up to 8 subwoofers, the
limit of the network daisy‐chain configuration. For larger sub arrays use one ODU to EtherCon for each side of the system giving
you a maximum of 16 subs in total, 8 subs per side which is likely to be plenty for all but the very largest venues.
PC Connection to the Master rack is either by WiFi or using the MLA Front of house rack which enables the Ethernet Copper Link
system allowing Ethernet runs of hundreds of metres over twisted pair cable using standard 3‐pin XLR cables, commonly a free
line on a returns multicore can be used.
As with other examples, Device Discovery in Vu‐Net will find all CSX‐Live subwoofers and MLA Compact allowing complete system
control and monitoring from a single platform on a tablet PC.
