Thorough and painstaking refinement has long been the secret to the excellent sound of a Marantz amplifier. For the PM-12SE, the Marantz engineering team used all its experience and expertise, both in the design of the amplifier and in the long listening sessions carried out for sound optimization. The Sound Masters team, located in Japan and Europe, did not finish their intensive work until they were absolutely certain that they had achieved a level of quality worthy of the Marantz name.

Marantz HDAM technology
Marantz developed its own discrete circuitry called Hyper-Dynamic Amplifier Modules, or HDAMs, to replace the chip-based amplifiers used in other products. Using discrete surface-mount components with short mirrored left and right signal paths, HDAMs dramatically outperform conventional integrated op amps in slew rate and noise level. The result is a much more dynamic, precise and detailed sound. Over the years, Marantz has developed different types of HDAMs to meet the needs of players and amplifiers. PM-12SE uses the latest high quality SA3 version. Combined with an optimized circuit layout and carefully selected components, the PM-12SE delivers outstanding sound quality and performance. |

Marantz Musical Premium Phono EQ
Marantz has taken its ongoing commitment to listening to vinyl records to new heights with the introduction of the Marantz Musical Premium Phono EQ stage. Designed to deliver optimum 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 amplifier. The phono stage uses two-stage amplification, combining Marantz HDAM modules with JFETs (junction-gate field-effect transistors) in the input stage, to achieve high input impedance. This further simplifies the design without using negative feedback, by eliminating coupling capacitors, again reducing distortion and improving signal purity. High quality volume control
The newly developed electric volume control uses the latest volume control IC to achieve better channel separation, better dynamic range and distortion reduction while maintaining the operating feel of an analog volume control device. The amplifier uses the new Marantz-designed electric volume control for high linearity and the best channel separation in its class. Current Feedback amplifiers
Current Feedback amplification is a famous Marantz original circuit technology designed to meet the requirements of high-resolution Super Audio music for ultra-fast, wide-bandwidth playback. The impedance at the current feedback point is limited, resulting in a very small 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 amplification rate, excellent transient response and superb sonic clarity across the entire bandwidth. Unlike conventional voltage feedback topology, Current Feedback also allows the power amplifier to be unaffected by demanding loudspeaker loads. Powerful Amplification
Drawing on the design elements of the PM-10, the PM-12SE is engineered to take advantage of the improvements, keep the purest sound possible, and produce the power needed to drive the most demanding loudspeakers. The PM-12SE's amplifier output stage makes available a large output power, delivering 2x100W into an 8 Ohm load, and easily drives demanding loudspeakers thanks to an output of 2x200W into 4 Ohms. The amplifier module is connected directly to the PM-12SE's rear panel circuit board 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 construction: many competing designs today include digital-to-analog conversion or adopt digital amplification and volume control, but Marantz keeps as much as possible clean and simple engineering, with its acclaimed all-analog design. It may seem convenient to have a DAC in your amplifier, but digital circuits are by their very nature noisy (in an electrical sense) and can interfere with the delicate analog signals passing through your amplifier. That's why Marantz has chosen to design its Premium Series range without any digital-to-analog conversion, keeping its amplifiers as pure as possible.
