Main features

Tri-tone control

This unit has a 3-tone control function for adjusting the midrange sound in addition to the bass and treble sounds so that you can make a more variable sound adjustment according to source and system.

All-Discrete current-feedback phono equalizer

As a phono equalizer amplifier for MM cartridges, a constant current-feedback PHONO equalizer of quality equal to that of the higher-grade model PM-11S2 is used.

All-discrete current-feedback amplifier

Marantz’ proprietary current-feedback circuit, using discrete components, is adopted in the pre amplifier and power amplifier. It is a high-speed amplifier using the latest technology developed for the higher-grade amplifiers.

Double-shielded triodal transformer

The unit is equipped with a toroidal power transformer to minimize vibration and leakage flux specific to the transformer.

Especially to reduce leakage flux, which affects sound quality, the periphery is double-shielded, using a core ring and a short ring.

HDAM-SA3 Technology

The V/I converter circuit, which is the key block of the current- feedback pre-amplifier and power amplifier, is equivalent to the HDAM-SA3 ampmodule developed for such higher-grade models as the PM-11S2.

CD direct buffer amplifier

An input buffer amplifier exclusive for CD is mounted near the CD input jacks. This is a high-speed buffer amplifier made with discrete components, which avoids interference between right and left channels and can send the signals to the pre-amplifier with very high fidelity.

Improved momentary current supply ability

It is generally known that the sound quality is not necessarily the same even if amplifiers have the same specifiations.

Marantz considers the cause to be the power to drive speakers. The power amplifier of this unit has the ability to momentarily supply current of 25 A or more to drive speakers strongly.

Short-power-line layout

For strong momentary current supply, a short power-line layout unifies the power circuit and output stage of the power amplifier section.

This layout allows connecting the large-current lines via the shortest route while to arranging the left and right channels symmetrically.

Block condenser of large capacity

A large-capacity condenser of 18,000μF is used in the power circuit of the power amplifier. In the preamplifier, a 4700μF condenser is used.

High-performance volume

Capacitor for high quality sound

Double-layered chassis

High-grade speaker terminals
