High quality sound

HDAM_®SA3 Module

This unit includes the HDAM_®SA3 which had been developed for high-end models. The HDAM_®SA3 is incorporated into many components, such as the current feedback phono equalizer.

All-stage Balanced Configuration Amplifier Circuit

This unit has an all-stage balanced configuration and the power amplifier receives output via a BTL (Bridged Transless) connection. Both the positive and negative terminals of the speakers are directly driven by the output stage of the power amplifier to exhibit a high drive capacity. Furthermore, since the drive current of the speakers does not flow directly into the ground circuit, the voltage that serves as the basis of the amplification is stabilized, reducing noise and interference between circuits, so that amplification is conducted accurately.

Linear Control Volume

The control knob had adopted the high-end model design concept. For better S/N ratio, the MAS6116 from Micro Analog Systems and the HDAM_®SA3 have been combined, which enables smooth adjustment in the range of 0 to −100 dB in units of ±0.5 dB.

Hypex Switching Power Amplifier Module

The power amplifier uses a total of 4 Hypex NCore_® switching power amplifier modules with BTL connections. The switching amplifier modules exhibit extremely excellent performance with minimal distortion from low to high frequency and no frequency response change regardless of speaker impedance. Combined use with a high-speed pre amplifier circuit using HDAM_®SA3 faithfully and precisely reproduces the detailed information in DSD and high-resolution sound sources.

Dual-Amplifier Structure

Amplifier of this unit has dual structure, pre amplifier and power buffer, adopting high-end model design concept. This dual structure enables the power buffer amplifier to drive the speakers powerfully, preventing influence from the back electromagnetic force from the speakers. The pre amplifier drives the power buffer with super-low distortion.

Constant Current Feedback Phono Equalizer

This unit incorporates the constant current feedback phono equalizer which had been developed for high-end models. This equalizer, developed by Marantz, has the advantages of both NF-type and CR-type phono equalizers, and it supports both MM and MC cartridges. The PHONO input terminal is also equipped with an input impedance switch. In addition to cartridges with medium to high impedance, it provides the optimal impedance for cartridges with low impedances of about 2 to 10 Ω/ohms which are representative of high-end brand cartridges.

High Sound Quality Parts Employed

High sound quality parts are used in every part of the circuit, including newly adopted high sound quality MELF resistors and film capacitors.

Display

This unit adopts an LCD (Liquid Crystal Display) to display the input source and volume level. Compared with other types of display panels, an LCD requires less drive power and generates less radiation noise, which minimizes any adverse effect on sound quality.

Double-layered chassis

High-grade Machined Copper Analog Audio Input Terminals (CD/PHONO Only)

High-grade Machined Copper Speaker Terminals

High performance

Purest Mode

Even greater improvements in sound quality are facilitated by cutting off the power supply of circuits not required when simply listening.

F.C.B.S.

A Floating Control Bus System (F.C.B.S.) enables the user to connect up to four PM-10 units, making a diversity of applications possible with complete bi-amp and multichannel connections. Moreover, a ground loop is not formed among multiple PM-10 units connected; therefore, sound quality is not adversely affected.

BI-AMP Mode

Complete bi-amp connection proposed by Marantz enables a level of reproduction of the acoustic field never before achieved. Synchronized operation of two PM-10 units is made possible by F.C.B.S. (Floating Control Bus System) connection, with each PM-10 in Bi-Amp mode working as a monaural integrated amplifier.

Power Amplifier Mode

In this mode, this unit works as a power amplifier.
