Once the supply is rackmounted, it should be connected to the
console using the factory supplied cable. The console’s power supply
connector is located at the rear of the console, at the right end of the
meterbridge bottom pan. If you are using one supply, connect it to the
console connector. If you are using two supplies (failsafe option),
connect the long power supply cable to the center connector of the
rackmount failsafe panel. Then connect one supply with a short cable to
either of the two remaining connectors on the failsafe panel and connect
the second supply with a short cable to the last connector. Note that the
power supply cable’s 10-pin female connector has to be rotated until its
locating pins match the male connector on the console. Do not force a
connector on; it attaches easily when properly aligned. Connect the
cable first to the console, then to the rear of the rackmount power supply.
Note each power supply is fitted with a 3-wire grounded AC cord that
should be plugged into a "clean" AC power source, that is, an AC source
that feeds only the control room audio gear. This source should be a
separate feed from those powering lighting, air-conditioning, or any
other non-audio machinery. The third pin ground wire of the AC source
should be tied to the central system ground point. Note that while the AC
power cord ground wire terminates at the power supply chassis, it does
NOT connect to the ALM-12d console common; the console itself must
be grounded separately. (See previous section, "System Ground".)
The power feed recom-
mended in the text is of-
ten installed and referred
to in studios as an “iso-
lated AC ground” outlet.
It is usually orange in
color.
