FEATURES

This is an integrated amplifier based on the SC-7S2/MA-9S2

flagship models from Marantz, using leading-edge technologies

developed for the higher-grade SC-11S1/SM-11S1 models.

¶ HDAM

SA3

The latest HDAM

SA3, featured in the higher-grade SC-11S1/

SM-11S1, is provided with this model. Compared with the

previous HDAM

SA2, the HDAM

SA3 has further improved

temperature stability and substantially higher-speed processing.

The HDAM

SA3 is incorporated into many components, such

as the current feedback phono equalizer, balance buffer, and

input buffer.

Input Amplifier Section

Constant Current Feedback Phono Equalizer

The Constant Current Feedback Phono Equalizer of the higher-

grade SC-11S1 model is also provided with this model.

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.

¶ Current Feedback Balance Buffer Amplifier

The Current Feedback Balance Buffer Amplifier, which

incorporates the HDAM

SA3 amp module, is provided with

this unit, in order to faithfully convey signals from Super Audio

CD players and D/A converters that have high-quality balanced

output.

¶ Dedicated Input Buffers for All Line Input

Jacks

Each CD, LINE 1, LINE 2, RECORDER 1, and RECORDER 2

input jack has its own input buffer amplifier that incorporates an

HDAM

SA3. Those buffer amplifiers prevent mutual interference

among input sources, for faithful transmission of signals from

input sources.

Preamplifier Section

¶ Linear Control Volume

The Linear Control Volume based on the design concept for

the SC-7S2 is incorporated. For better S/N ratio, the WM8816

from Wolfson 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.

¶ Tone Control Amplifier

The electronic tone control amplifier is provided for adjustment

of bass (low frequency) and treble (high frequency) sound in

units of 2 dB in the range of -8 to +8 dB. Adjustment can be

separately performed for the L and R channels, using the remote

control unit.

Power Amplifier Section

¶ Dual-Amplifier Structure

Following the design concept of the MA-9S2, this unit was

developed with the dual structure of a voltage amplifier and

power buffer amplifier. This dual structure enables the power

buffer amplifier to drive the speakers powerfully, preventing

influence from the back electromagnetic force from the speakers.

The voltage amplifier drives the power buffer with superlow

distortion.

Power Circuit

¶ Choke Input Power Supply Circuit

This unit incorporates a choke input power circuit that uses

a large-capacity smoothing capacitor, in order to thoroughly

eliminate high-frequency noise from the rectifier circuit and

external sources. The choke input power circuit supplies clean

power to the input amplifier and preamplifier sections.

Functions

¶ BI-AMP Mode

Complete bi-amp connection proposed by Marantz enables a

level of reproduction of the acoustic field never before achieved.

That complete bi-amp connection is available with the PM-11S2.

Synchronized operation of two PM-11S2 units is made possible

by F.C.B.S. connection, with each PM-11S2 in Bi-Amp mode

working as a monaural integrated amplifier.

¶ F.C.B.S.

A Floating Control Bus System (F.C.B.S.) enables the user

to connect up to four PM-11S2 units, making a diversity of

applications possible with complete bi-amp and multichannel

connections. Moreover, a ground loop is not formed among

multiple PM-11S2 units connected; therefore, sound quality is

not adversely affected.

¶ 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.
