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.
