The final step is to tidy the cables to keep the loom neat, particularly any spare Ceeform cables if your array is smaller than 12
boxes. Over-hanging cables should be neatly coiled and taped behind the array so they are invisible to the audience.
Arrays greater than 12 enclosures
Rigging arrays up to 24 enclosures is exactly the same mechanically as smaller arrays. The same technique is used adding each
additional MLA, connecting the cabinets as they are added to check that they power up and show good network connectivity.
Network and audio connections link between adjacent cabinets all the way to the bottom of the array, the only issue is powering
cabinets when you exceed the 12 enclosures that are catered for by the 12-way mains break-out loom.
It has been discovered in practice that the power consumption of MLA is very small indeed, well below the 16A rating of the
Ceeform inlet connector or RCD breakers in the mains distro, particularly for the cabinets at the bottom of an array which as you
might expect are not driven as hard as those at the top which are required to reach greater distances. For that reason it is
perfectly acceptable to use Ceeform ‘Y’ splits to double the number of cabinets on a single Ceeform cable feed. You can
comfortably do this for arrays of up to around 16 enclosures. For up to 24 you will need to add a second Tourmate feed and 12-
way breakout loom.
The distro hanger has a second flying pin and hole which is provided as a means to support a second 12-way break-out. If the
upper section of the array is fed by a 12-way loom connected to the middle hole in the distro hanger, the end hole is used to pin
a length of steel rope with a loop at each end which is supplied with the MLA flying frame assembly. The rope is the right length
to attach the second distro hanger behind cabinet 13 so it can be used in the same way as the distro at the top of the array with
