The Millennia LOCi Playback Equalizer is a hand-crafted combination of Millennia's 100% DC coupled preamp and equalizer circuitry, tailored specifically for the needs of archiving and mastering engineers.

The Millennia LOCi Playback Equalizer offers a selectable mono or stereo playback environment which can be used with any modern or legacy phonograph cartridge. Any known style of record pressing can be compensated perfectly with the LOC, including vertical groove processes. When the LOC does not offer a precise preset compensation point, a user may define virtually any compensation via passive plug-in components. Audiophiles requiring a sonically uncompromised phono path will also benefit. The LOC was originally specified under contract for the U.S. Government (Library of Congress, Culpeper VA). Since then, the LOC has been acquired by archiving and mastering labs throughout the world. One listening session with the LOC will immediately confirm that Millennia has once again set precedence in musical realism and sonic transparency.

LOC employs a 100% discrete design topology from input to output, utilizing both discrete bipolar and field-effect transistors where they are optimally applied for Millennia's hallmark sonic invisibility. The LOC accepts balanced line-level or phono-level input via gold XLR connectors. Unbalanced RCA inputs are also provided. Ten discrete outputs are provided on both gold XLR and RCA phono connectors. Mains powering is worldwide (100V-240V). The Legacy offers forty-nine combinations of preset compensation curves for precise performance with all formats, including 33-1/3 (RIAA), 45, and a vast array of 78 RPM EQ formats. Legacy’s phono compensation network has only one active amplifier stage in the audio signal path. Compare this with textbook phono designs employing anywhere from two to five compensation path amplifiers. Fewer amplifier stages means greater sonic integrity and heightened musical reality. This single all discrete Class-A stage is optimized as input buffer, compensation amplifier, and output driver. It's something you must hear to appreciate. Legacy’s phonograph preamplifier design is based upon Millennia’s acclaimed HV-3 Cohen topology, a world standard in classical and critical acoustic music production. Utilizing a 100% discrete FET, fully differential balanced design — phono signals remain differentially balanced throughout the entire preamplifier path.
