technician any and all servicing and other operations which
require the top cover to be removed.
Congratulations on your purchase of the Millennia Media LOC Analog Legacy archive refer-
ence system. The LOC is the culmination of meticulous listening tests on innumerable circuit,
topology, and packaging designs over many years of product design and development. Your
LOC is a finely tuned instrument intended for critical professional applications — we feel it
offers the world's most sonically invisible and versatile phonographic front-end.
Before connecting power to the LOC, assure that the rear panel voltage selection fuse block
switch is set correctly. In the USA and Canada, the LOC is shipped with the voltage selection
block set to 100-120 VAC. If you change the voltage selection block to 200-240 VAC usage,
be sure to change both fuses to the correct types. See "Rear Panel" instructions for proper
fuse requirements.
The LOC enclosure measures approximately 19" wide x 3.5" high x 15" deep and is designed
for mounting into a standard 2U, 19" equipment rack. If the LOC is mounted in a road case
or other rack which is prone to strong vibration or shock, it is highly recommended that the
rear of the LOC be supported or otherwise reinforced to withstand such conditions. The LOC
Analog Legacy
runs warm and should be mounted with at least one rack screw space open
above and below the unit.
The LOC is designed on a common ground topology. For high quality operation, and for your
own safety and the safety of others, do not defeat the purpose of the AC plug earth ground-
ing pin.
INTRODUCTION
The LOC Analog Legacy is a hand-crafted collection of Millennia's essential preampli-
fier and equalizer circuitry tailored specifically for the needs of archiving and master-
ing professionals, and serious audiophiles requiring a sonically uncompromised ana-
log front-end. The LOC is a selectable mono or stereo processing chain which can
be used with virtually any modern or legacy phonograph cartridge. Any known type of
legacy record pressing (78, 45, 33, etc.) can be compensated perfectly with the LOC,
including vertical groove processes.
When the LOC does not offer a precise preset compensation point or loading charac-
teristic, the user may define virtually any custom parameter via plug-in passive com-
ponents. The LOC offers a discrete-hybrid signal path from input to output, employing
both bipolar and field-effect transistors where they are best applied for Millennia's
hallmark sonic invisibility and dynamic uniformity. The LOC accepts balanced line
level or phono level input via gold XLR connectors. Outputs are both XLR and RCA
phono. Mains powering is worldwide, universal.
