Marantz SA12SE – Super Audio CD Player with DAC

The SA-12SE is a fully functional digital-to-analogue converter for music stored on a home computer via USB-B and features optical and coaxial digital inputs for existing source components. These inputs support files up to 192kHz/24bit. The USB-B asynchronous input for direct connection with a computer is compatible with PCM and DXD music files at up to 384kHz/32bit, as well as DSD2.8MHz, DSD5.6MHz and DSD11.2MHz.

Marantz developed its own discrete circuit boards called Hyper-Dynamic Amplifier Modules, or HDAMs, to replace the chip-based amps used elsewhere. Using discrete surface mount components with short mirror-image left and right signal paths, HDAMs outperform the regular integrated Op-amps dramatically in Slew Rate and noise level. The result is much more dynamic, accurate and detailed sound. Over the years, Marantz has developed different HDAMs to fit the requirements of players and amplifiers. The SA-12SE uses the latest high-grade SA3 version. Combined with optimized circuit design layout and carefully selected components, the SA-12SE provides exceptional sound quality and performance.

Marantz Musical Mastering is at the heart of digital audio in the SA-12SE lies DSD. PCM signals are up-converted to DSD at 11.2MHz using the proprietary MMM-Stream converter within the player. The high-frequency signal produced is processed by the unique MMM-Conversion stage, used in place of a conventional DAC, to produce the analogue output. The MMM-Stream section of the process replaces the oversampling filters normally used in digital to analogue conversion and allows the implementation of the Marantz Musical Mastering filtering. Two system clocks of 44.1kHz and 48kHz ensure the most accurate up-conversion of the incoming signal, whether it is from disc or the digital inputs. All available digital signal formats are a multiple of either 44.1 or 48, hence any processing is done without rounding, preventing the loss of important information or creating failures. Sigma Delta Modulation allows a pure DSD-standard signal, a 1-bit stream, to be passed to the conversion section in the form of a very high-frequency stream of pulses. The design of the DSD-to-analogue filter feeds the audio signal into the familiar Marantz HDAM (Hyper Dynamic Amplifier Modules) in the output stage for optimal sound quality.

The power supply of the SA-12SE features a large high current toroidal power transformer with OFC (oxygen-free copper) secondary wires, along with high speed, high current Schottky Barrier Diodes in the rectifier stage for the purest DC voltage output. There are independent power supplies for the analogue and digital circuitry to reduce interference to a minimum.

The elegant aluminum top remote control features an intuitive ergonomic layout and is equipped with amplifier control functions to operate both the SA-12SE and the complementary PM-12SE reference class integrated stereo amplifier. Use the integrated remote control input and output jacks to connect the SA-12SE to other compatible Marantz components. An internal/external switch on the rear panel provides additional system control flexibility.

Like the complementary PM-12SE integrated amplifier, the SA-12SE Super Audio CD player is constructed to the highest standards, with a front panel made from thick, heavy, non-magnetic aluminum to eliminate interference. Single layer nickel-plated matching copper RCA terminals in the SA-12SE outperform the terminals of competitors and offer an exemplary listening experience.

The deluxe low noise LC display features clear, easy to read alpha-numeric characters and is compatible with CD Text encoded music discs. Display can be turned off via the display control button on the remote. For enhanced user experience, bit depth of the input signal is now available on the front display of the SA-12SE.

Founded in 1953, Marantz has a long and rich history of designing audio components embraced by music lovers and critical listeners around the world. Because Music Matters, the SA-12SE carries on the tradition of delivering a best-in-class listening experience for music and cinema.
