Audio - Martin Audio MLA User Manual

MLA System
the Picostation system as during the show when the venue is full of people with Smart Phones you will almost certainly find that
Wi-Fi becomes heavily congested and range will be extremely compromised. Ethernet connections are available on the patch
panel of the Master Rack just below the U-Net connectors;-
These are fed from the Ethernet switch which also connects the Merlin and Wi-Fi components so all are available on a single
Ethernet network. From this connection point you can connect to the PC and to all slave racks being used, most frequently a
single Slave on the opposite side of the stage. Any network cable can be used for Ethernet connections excluding the 120m
PWA00041; the maximum cable length for Ethernet is approximately 100m.
Note that Mk1 Slave racks have the same patch panel but as there is no Ethernet switch the Ethernet connections are blanked
off leaving just a single one available which is the Ethernet connection to the Merlin.
Note also that you cannot connect several Master racks together, each Master Rack has an integral DHCP device to assign IP
addresses to all components therefore you can only have one Master. All other racks must be configured as slaves. This could
still include a Master with the Ethernet switch if the DHCP support is disconnected (Picostation device in the Mk1 Master Rack).
That way the system can be expanded to include more racks by using the Switch in its basic mode.

Audio

Audio into an MLA system is extremely straightforward; a single balanced XLR feed to each array is all that is required. This can
be standard analogue or AES3 Digital, the connection type is selected via Vu-Net. Audio cables to reach to the top of each array
are supplied with the system as are the links to go between cabinets. The Merlin can also be used to process audio if required,
even if just as a simple routing matrix. All audio connections are brought out on the patch panel;-
As well as all ten outputs being available there is a parallel connection to all four inputs to make it easy to daisy-chain audio
feeds between racks if necessary.
