At CEDIA 2012, HARMAN Luxury Audio Group is showcasing its Mark Levinson 40th Anniversary № 52 Reference Dual-Monaural Preamplifier.

“We are excited to offer the № 52 to music lovers and audio connoisseurs worldwide,” said Jim Garrett, Director of Marketing and Product Management for HARMAN Luxury Audio Group and Loudspeakers. “The № 52 embodies the uncompromising technological innovation, superlative sound, unmatched build quality and striking design that has made Mark Levinson synonymous with ultimate-performance audio for 40 years. We designed the № 52 to deliver the highest level of sonic accuracy and musical involvement.”

The № 52 is an all-analog, dual-monaural design with a two-chassis configuration that separates the critical analog audio circuitry from the control section to maintain the purest signal paths possible. It provides a comprehensive complement of inputs including three balanced XLR and four unbalanced RCA line-level inputs, and a dedicated phono input that is selectable for moving coil (MC) or moving magnet (MM) operation. Two sets of XLR and RCA stereo preamplifier outputs are provided, along with an auxiliary pair of XLR and RCA outputs that can be configured for fixed or variable level output with independent source selection. This enables the auxiliary outputs to function either as a third preamp out, a pass-through full-range subwoofer output or a record output.

The Mark Levinson № 52 offers a unity gain SSP (surround sound processor) output that provides the ability to integrate the audio sources that are connected to it into a home theater system, while maintaining independent stereo operation for music sources. The № 52 provides extensive control and system interface connectivity via Ethernet, Mark Levinson’s proprietary ML Net, 12V trigger and IR control ports. In addition, a USB port facilitates possible future software upgrades. The № 52 is supplied with a remote control that can also be used to operate other Mark Levinson components.

Its control section features mirror-imaged DC power supplies and AC regeneration circuits for a clean and stable power delivery and signal purity. Individual left and right DC umbilical cords are used to connect to the audio sections in the second chassis, and control signals are delivered via a third cable to keep them isolated. The audio chassis is laid out in a mirror image, left/right configuration with isolated and independent circuit boards for the volume, main and auxiliary signal paths, and extensive shielding for critical components. The chassis is constructed from heavy aluminum extrusions and plates.

The Mark Levinson № 52 Reference Dual Monaural Preamplifier will be available in January 2013.
