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,

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.

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.
