Marantz Special Edition
|Extensive and painstaking tuning by sound masters is what powers the exquisite sonic signature of any Marantz product. No component leaves the hands of Marantz Sound Masters until it passes rigorous testing. Only the finest products, thoroughly tested and tenderly handled, make it to your home.|
Marantz Special Editions are the Marantz way to celebrate the love of music that runs deep in the veins of Marantz sound masters and engineers, exhibited in the artistry and craftsmanship of those special components. Sound Masters will occasionally identify a product with a higher potential than expected and master it with extra unwavering attention to detail, component selection and listening sessions. The original PM-12 was solely created for the Japanese market, and quickly proved to be the next chosen one. European sound engineers combined it with achievements made developing the famous PM-KI Ruby, and thus the PM-12 Special Edition was born.
Extensive Sound Tuning
Extensive and painstaking tuning has long been the secret of fine sounding Marantz amplifiers. For the PM-12SE, the Marantz engineering team used all their experience and expertise, both in the design of the amplifier and in the long listening sessions involved in finalizing the sound. The team of Sound Masters located in Japan and Europe didn’t stop their intensive work until they were absolutely certain they reached the height of quality worthy of the Marantz name.
Marantz HDAM Technology
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 particular requirements of players and amplifiers. The PM-12SE uses the latest high-grade SA3 version. Combined with optimized circuit design layout and carefully selected components, the PM-12SE provides exceptional sound quality and performance.
Marantz Musical Premium Phono EQ
Marantz took its ongoing commitment to vinyl to new heights with the introduction of Marantz Musical Premium Phono EQ stage. Designed to deliver optimal sound quality by simplifying the signal path — vital given the delicate nature of phono signals — the Phono EQ stage in the PM-12SE amplifier can be used with both moving magnet and low-output moving coil cartridges, thanks to a built-in MC head amplifier. The phono stage uses two-stage amplification, combining Marantz HDAMs with JFETs (junction gate field effect transistors) in the input stage, giving high input impedance. This allows the no-negative-feedback design to be further simplified by the deletion of coupling capacitors, again reducing distortion and enhancing signal purity.
High Quality Volume Control
Newly developed electric volume control uses the latest volume control IC to realize better channel separation, dynamic range and distortion-reduction, while retaining the operational feel of an analog volume control device. The amplifier employs new Marantz-designed electric volume control for high linearity and best-in-class channel separation.
Current Feedback Amplifier
Current Feedback amplification is a well-known, Marantz-original circuit technology, thoughtfully designed to match the requirements of Super Audio hi-res music for wide-bandwidth, high-speed reproduction. The impedance at the Current Feedback point is limited, generating a very low phase shift. Marantz Current Feedback amplifiers reduce the need for phase compensation by minimizing Negative Feedback (NFB). This simplifies the signal path and results in a high through-rate, excellent transient response and superb sonic transparency across the full bandwidth. Unlike conventional Voltage Feedback topology, Current Feedback also makes the power amplifier insensitive to difficult loudspeaker loads.
Drawing on design elements of the PM-10, the PM-12SE is built to leverage enhancements, maintain the purest possible sound and support the power needed to drive the most demanding speakers. The amplifier output stage of the PM-12SE allows a large power output, delivering 2x100W into an 8ohm load, and easily copes with high-impedance speakers thanks to a 2x200W output into 4ohms. The amplifier module connects directly to the rear panel PCB on the PM-12SE to maintain signal purity and sound stability.
Pure Analog Design
The purely analog design of the PM-12SE contributes to its noise-reduction structure and clean build: many rival designs are today including digital-to-analogue conversion, or adopting digital amplification and volume control, but Marantz keeps things as clean and simple as possible with its acclaimed all-analogue design. It may seem convenient to have a DAC in the amplifier, but digital circuitry is by its very nature, noisy (in the electrical sense) and can interfere with the delicate analogue signals passing through the amp. That’s why Marantz chose to design its Premium Series range without any digital-to-analogue conversion, keeping its amplifiers as pure and clean as possible.
There’s also a Power Amp input, taking the signal straight from the input section to the power stage to let the unit work as a pure power amplifier.
Carefully Selected Components
Marantz has a steadfast reputation for choosing the best-possible components for its Premium Series products. The Marantz alternative to the “amplifier on a chip” IC components, the HDAM, is a miniature amplifier module built entirely of discrete components. Marantz engineers selected and optimized the HDAM through extensive listening in dedicated Marantz facilities in Europe and Japan. Extensive, painstaking and meticulous tuning has long been the secret of exquisite-sounding Marantz amplifiers. During the development stage, every part is carefully selected, tested and validated by Marantz audio engineers to ensure audio perfection every time you listen.
Multiple Analog Inputs and Outputs
In addition to phono and CD analog inputs, the PM-12SE features two line-level inputs and two pairs of recorder input/output jacks that enable the connection of multiple sources and recorders. Use the PM-12SE as a stand-alone stereo power amplifier or as an power amplifier via the power amp direct input. For example, use the front pre-outs of your AV setup and run them through PM-12SE power amps.
