MLA Master Rack

Mk1 Master

The Master rack is housed in a 16U 19"rack flightcase and is the principal control for any MLA or MLA Compact System. It houses
either one or two Mains distros to power up to four arrays, a Merlin processor, a Pakedge Ethernet switch, Merlin Patch Panel
and the Picostation DHCP server and associated power supplies. System wiring is as follows;-
This also shows the Picostation WAP and antenna which are supplied with the Front of House Tablet PC assembly. The two
Ubiquiti Picostation devices are identical however one is configured as a DHCP server and the other as a Wireless Access Point
(WAP). Both are powered via their Ethernet ports using a PoE (power over Ethernet) mains PSU which is in line with their Ethernet
connection. The DHCP server is connected to one port of the Pakedge Ethernet switch another port is connected to the connector
designated for use with the WAP. Note that the PoE adds 48V to the connection; do not connect any other Ethernet devices to
this connector as damage could occur. The first 5 ports of the Switch are directly connected to the Ethernet outputs on the patch
panel for connection to slave racks or a cable connection to the tablet PC.
Not shown in the diagram are the two U-Net connections from the patch panel which are terminated in Neutrik Ethercon
connectors to connect to the two ports on the Merlin.
All input and output audio connections on the Merlin are connected to the patch panel with short cables.
The mains cables for the two PoE devices, the Ethernet switch and Merlin are run down the back of the rack to the 13A outlets
on the Mains Distro. These are powered from breakers 3, 6, 9 and 12 on the Mk1 distro.
All Networking and Wi-Fi wiring is identical on the low voltage (USA) version of the Master rack; the only difference is the mains
distro and flightcase.
