The LOC Analog Legacy phonograph playback system is a hand-crafted collection of Millennia's essential, 100% DC coupled preamplifier and equalizer circuitry tailored specifically for the needs of archiving and mastering pro-fessionals. Audiophiles requiring a sonically uncompromised phono path will also benefit.
The LOC 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.
LOC Legacy design employs a discrete-hybrid 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. Outputs are both gold XLR and RCA phono. Mains powering is worldwide.
The Legacy offers forty-nine combinations of preset compensation curves for precise performance with all formats, including 33-1/3 (RIAA), 45, and 78 RPM records. 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 mic preamp topology, a world standard in classical and critical acoustic music production. Utilizing a discrete-hybrid, fully differential balanced design — phono signals remain differentially balanced throughout the entire preamplifier path — the LOC features 36 discrete gain steps of 1.5 dB per step to 60 dB (up to 90 dB upon request), user-selectable (unlimited) capacitive and resistive loading, mono and polarity select switching for vertically grooved pressings, stereo gain matching to .08 dB, and an entirely transformerless audio signal path.
Rounding out the LOC feature set is a collection of four surgical filters which will isolate and correct problem areas associated with groove degradation and surface noise. Legacy filters offer both shelving and peaking response with a number of user-selectable frequencies via Grayhill military grade gold contact rotary switches. If not required, all filter sections can be removed entirely from Legacy’s signal path for increased sonic integrity.
Legacy’s pure Class A amplifiers are carefully designed around the finest grades of passive components from Vishay, Roederstein / MELF, Wima, Toroid Tech, and German ITT. Key electro-mechanical design features include a 16 gauge cold-rolled plated steel chassis (26 pounds), 3/8” thick radiused aluminum face panel which is deeply polished in a “piano lacquer” black anodize finish, hand machined and polished black aluminum knurl knobs, and custom molded illuminated switches.
One listening session with the LOC will immediately confirm that Millennia has once again set precedence in musical realism and sonic transparency.
