Components that bring music to life!

The Marantz Tradition
The name Marantz is, if anything, more prominent today than when Saul B. Marantz founded the company in 1953.
Even in those early days, perhaps no one - and no company - was as recognized for the passionate pursuit of high quality sound reproduction.
f any one thing stood out from the beginning, it was Saul's insistence that good industrial design was as important as superior
performance. Arresting cosmetics, he knew, would play an essential role in bringing electronics out of the garages and basements and into the living rooms of
music lovers everywhere.
ndeed, Saul's early training was in the graphic arts even though his interest in electronics began while he was very young. As it did for many, service in World
War gave him the opportunity to enlarge his hobbyist's knowledge.
Music, long a part of his life, took on an even more important role after he returned to New York City from the Pacific Theater. Marantz joined the New York Society
of Classical Guitar where he became both a serious student of the instrument and a close friend of guitar maestro Andrés Segovia.
This combination of design sensibility, knowledge of electronics, love for music, and an uncanny ability to envision better ways to
reproduce music in the home eventually led to the development of the "Audio Consolette," a unique preamplifier, and to the founding of the Marantz Company.
Supported by a growing engineering team led by the now-legendary Sidney Smith, and staffed by such luminaries as Dick Sequerra, Mitch Cotter, and many
others, Marantz soon gained an international reputation for outstanding performance and cosmetic sophistication.
Many products, especially the Model 7 preamplifier and the Model 9 monaural power amplifier, were nothing short of revolutionary. n fact, they are icons still,
and their superb performance and timeless elegance continue to influence our most capable designs.
The current Marantz Reference Series is the best contemporary expression of these long-held strengths. f ever the word "inspiration" has meaning, you'll find it
in this Reference collection.
Marantz Reference. The highest reward you can offer your auditory sense... and your aesthetic expectations.

SC-7S2
Stereo Control Amplifier
A singular integration of performance, functionality, and design, the
SC-7S2 thoroughly updates the concept of a stereo preamplifier.
Although it traces its sonic heritage to the distinctive voice of the
original Marantz Model 7, the SC-7S2 is not tied to even the best
of past technology. A significant improvement over the acclaimed
SC-7S1, the S2 version incorporates a full roster of technical
refinements to enhance your perception of even the most complex
musical compositions.
Simultaneously, the SC-7S2 avoids any aura of techno-intimidation.
nstead of an often confusing array of knobs and switches, it spaces
nput Select, Power, and Volume across a finely-finished champagne
front panel. An aluminum-topped remote control adds critical but less-
often-used functions such as input trim and display intensity to
tailor the SC-7S2 to your preferences.
n its quest for musical accuracy, Marantz gifted the SC-7S2
with refinements that define advanced audio circuitry. These include
a sophisticated power supply based on a toroidal transformer
for reduced spurious noise. Further refinements contribute to the
SC-7S2’s extraordinary frequency response and channel separation.
solated inputs eliminate unwanted interactions. All signal paths,
including the critical volume control section, are fully balanced to
minimize noise. n fact, the volume control benefits from multiple
microprocessors that eliminate distracting clicks when changing
volume settings.
Together, the microprocessors and an array of HDAM modules form an
incredibly precise attenuation circuit with easily repeatable 0.5 dB
steps throughout its entire range to insure proper channel balance at
any listening level.
Of even greater importance is the inclusion of the SA version
of Marantz’s proprietary HDAM® (Hyper Dynamic Amplifier Module)
circuitry. These modules insure accurate and distortion-free audio
signal transfer from one stage to the next.
Although the SC-7S2 is devoutly two-channel, it acknowledges the
multi-channel world with our Floating Control Bus System (F.C.B.S.)
that lets you control multiple SC-7S2s simultaneously for full
Reference-level performance.
A copper-plated aluminum chassis with a double layered bottom plate,
provides exceptional stability as well as isolation from external noise
sources.
The SC-7S2 Control Amplifier is an enduring testament to the synergy
of today’s technologies, meticulous implementation, and exquisite
cosmetic design. t is a reference in every sense of the word.

MA-9S2
Monaural Power Amplifier
“Wi hou music life would be a mis ake.”
- Friedrich Wi he m Nietzsche, Phi osopher/Phi o ogist
f the SC-7S2 is the flexible control center for the finest audio systems, the
MA-9S2 power amplifier melds acute sonic responsiveness with brute force
to precisely control even the most difficult loudspeaker.
One specification will make this clear. The MA-9S2 develops an impressive
300 watts continuous output into a typical speaker. Even when coupled to
a high quality, low impedance speaker, one that quickly taxes conventional
amplifiers due to extremely low electrical resistance, power output doubles
to 600 watts! Rather than power for power’s sake, this is simply
the intelligent application of engineering expertise. t insures that you will
enjoy music’s finest details without limitation.
n this, the MA-9S2 conforms to the tradition of the original Model 9 and
the more recent MA-9S1. Both provided a unique combination of high
resolution and high power. The MA-9S2, however, surpasses both to meet
the challenge of today’s most demanding sources.
n mapping the MA-9S2’s development strategy, Marantz engineers focused
on several performance areas: better instantaneous current delivery,
full-scale use of current-feedback design, and fully balanced audio circuitry.
Although these may seem esoteric to non-engineers, they form the platform
for music reproduction beyond conventional expectation.
Connectivity also played an important role. The MA-9S2 features both
single-ended and balanced input connectors and dual sets of precision WBT
speaker terminals to accommodate your choice of speaker cables. There’s a
heavy duty detachable AC cord to help installation in a custom cabinet if you
so desire.
But the MA-9S2’s stunning fascia may well argue against this.
The elegantly smooth front panel is finished in restrained champagne
gold. Highlighting this are four elements, one of them a remarkably
accurate power meter. Thus, the MA-9S2 complements décors
ranging from talian rococo to Scandinavian. And complements
your sonic expectations with the finest sound available.
Thus, the MA-9S2 is another example of Marantz’s dedication to con-
tinual advancement guided by the traditions of its illustrious past.
t is a true reference in every way.

SC-11S1
Stereo Control Amplifier
The SC-11S1 stereo control amplifier focuses a wealth of new circuitry
on reproducing music’s finest moments. t is a preamplifier that is
both totally new and classically Marantz.
Today’s musical sources demand ultra-wide frequency response and
superior channel separation for convincing musicality. Although aimed
primarily at stereo reproduction, the SC-11S1’s F.C.B.S (Floating
Control Bus System) allows easy expansion and operation for those
who enjoy the many forms of multi-channel material. At the same time,
the SC-11S1 honors legacy sources like the LP with a phono stage
incorporating a newly developed Marantz-proprietary circuit.
Parts quality reflects our premium-only philosophy. For example, the
SC-11S1 incorporates the newest SA3 version of Marantz’s acclaimed
Hyper Dynamic Amplifier Module (HDAM®). This high speed circuit
defines the SC-11S1’s ability to accurately track rapidly changing
audio signals.
The phono equalizer is yet another example of Marantz innovation.
Conventional designs often impart a different – and disconcerting –
sonic characteristic to low and high frequencies. Marantz engineers
designed a circuit that eliminates those sonic discontinuities. The
result is extremely accurate and convincing phono reproduction with
the cartridge of your choice.
The SC-11S1’s volume control exhibits exceptional accuracy and no
audible “stepping” noises. The controller lets you select exact volume
settings easily and is unaffected by aging or temperature variations.
The SC-11S1’s fully independent headphone output adds a new
measure of clarity to personal listening. The front panel display
provides information on input selection and level among other
parameters. You can turn the display off for distraction-free listening.
The aluminum-faced remote accesses a selectable subsonic filter, tone,
and level trim, and balance adjustments so you can choose the best
combination for your tastes and source materials.
All active circuitry draws on a high-precision linear power supply based
on an aluminum-encased toroidal transformer that far surpasses
conventional noise-free requirements. The chassis itself is also heavy-
duty and features a new aluminum top plate for resonance control.
There’s a natural fluidity to everything you’ll hear through this
remarkable preamplifier. t adheres to Marantz tradition but sets
new standards in long-term listenability. t is, after all, a Marantz
Reference component.

SM-11S1
Stereo Power Amplifier
“Music is wha feelings sound like.”
- Author Unknown
Many early Marantz power amplifiers produced comparatively modest
power. n that light, the SM-11S1 – with its 110 watt per channel power
rating – holds to this tradition. But Marantz tradition also mandates
innovation. And so the SM-11S1’s output doubles to 220 continuous
watts per channel when delivering power to low impedance speakers.
A “bridging” circuit lets you configure the SM-11S1 as a monaural amplifier
delivering 420 watts. n any mode, the SM-11S1 generates truly exception-
al control and delineation of the most complex sources.
But brute force without finesse serves no real purpose for the sonically
sophisticated. To that end, Marantz engineered many new techniques. At
the circuit board level, precise signal path positioning minimizes channel
interference for superior ambience reproduction and soundstaging.
The SM-11S1 also boasts the newest SA3 version of Marantz’s Hyper
Dynamic Amplifier Module (HDAM®) technology so it instantaneously
responds to any signal. And the SM-11S1, as do all Marantz Reference
components, resists the kind of destructive interaction with loudspeakers
that can degrade audible performance.
The high-current power supply boasts a toroidal transformer fully as
large as that used in our flagship MA-9S2 monaural power amplifier.
Configured for stereo use, this transformer feeds innovative power supply
circuits that allow the SM-11S1 to perform optimally under even the most
demanding conditions.
Of course, the SM-11S1’s high quality parts – even the precision WBT
speaker cable terminals – were chosen only after extensive listening tests to
determine their positive contributions to overall sound quality.
The SM-11S1 benefits from more easily observed qualities also.
t accepts balanced XLR inputs and easily switches between
stereo and bridged-mono modes. A remote power turn-on
circuit lets you activate the amplifier from a preamplifier or
surround processor. And the front panel digital power meter
monitors output with magnetic sensors that do not interfere
with the audio signal.
The subtly-curved front panel echoes the SM-11S1’s internal
sophistication with a substantial yet décor-conscious design
equally at home in a custom cabinet or on an open shelf.

PM-11S2
Stereo ntegrated Amplifier
A styling exercise worthy of Saul Marantz himself, the PM-11S2
integrated amplifier is stunningly functional with performance directly
traceable to the cost-no-object SC-7S2 preamplifier and MA-9S2
monaural power amplifier. t is a prime example of the axiom that
ultimate finesse often begins with brute over-engineering.
The power supply, for example, features a massive toroidal transformer.
Completely covered by an aluminum case and supported by other equal-
ly sophisticated components, it provides high instantaneous
current capability and quicker response than conventional
circuit elements.
The preamplifier section features fully balanced circuitry with liberal
applications of Marantz’s newest SA3 version of its proprietary Hyper
Dynamic Amplifier Module (HDAM®). Sonically, they help provide the
silken response so prized by audiophiles.
Buffered inputs virtually eliminate unwanted interactions between
source components and the PM-11S2. This is a critical consideration in
light of the PM-11S2’s wide variety of balanced and single-ended line-
level inputs. The precision phono stage, increasingly rare in any compo-
nent, is optimized for both moving magnet and moving coil cartridges.
The PM-11S2 benefits from a new high-precision digital volume control
augmented by more HDAM® devices. t provides easily repeatable and
noise-free gain changes.
On the amplifier side, the PM-11S2 evidences a meticulous level
of attention. Each channel echoes the MA-9S2’s two stage design
to provide the force needed to control virtually any loudspeaker.
The end result? With the ability to “double down” power into low
impedance speakers, the PM-11S2 often surpasses the control
capability of so-called “super amps.”
The rigid copper-plated chassis provides a firm foundation for all
internal components. Two sets of WBT speaker terminals and front
panel A/B speaker switching add a rare level of convenience. And our
proprietary Floating Control Bus System (F.C.B.S.) synchronizes up to
four PM-11S2s for multi-channel applications.
The front panel is as advanced as the circuitry behind it. ndirect blue
LEDs display status with a décor-friendly elegance. The display, a “zero
noise” LCD, exacts no performance penalty as it keeps you informed
about the PM-11S2’s operation.

A Vibrant Tradition that Spans the Decades . . .
Ken Ishiwata has followe the tra ition first efine by Saul Marantz more than half a century ago. But this shoul not be a surprise as both men
share similar gifts as esigners, music lovers, musicians, an visionaries.
Now, Ken Ishiwata celebrates his thirty year commitment to the Marantz tra ition with his Pearl series of extraor inary components. Base on
Marantz Reference Series engineering an nurture by Ken Ishiwata’s critical ear, the SA-KI-Pearl SA-CD Player an the PM-KI-Pearl Integrate
Amplifier may well be the finest of their type.
The isc player repro uces the palpable soun staging an subtle nuances inherent in the finest SA-CDs an CDs. The amplifier combines the
power to control virtually any lou speaker an the sonic accuracy to repro uce the rich etail of the most involving music with exceptional
warmth an elicacy.
Together, they form the heart of a music system without peer.
Treat your ears to the soun of Marantz. An Ken Ishiwata’s remarkable talent in furthering that tra ition.
K I-PEARL SERIES

The SA-KI Pearl’s striking deep black finish may be the first design
element you notice. But its stunning reproduction of music will
quickly carry your perceptions from the listening room to an
artist’s soul.
Both science and art contribute to this journey. Under its elegant
and multi-layered brushed aluminum skin, the SA-KI Pearl
SA-CD player rests on thick machined legs which, in turn, support
a heavy copper-plated chassis that protects internal circuitry from
mechanical vibration and radio frequency interference.
Inside that solid foundation, you’ll find a power supply built
around a large toroidal transformer that is itself double-shielded by
a silicon steel belt and copper-plated case.
The transport mechanism with yron disc tray is a proprietary
design specifically tuned to Ken Ishiwata’s specifications. An
adjustable filter ideally conditions the digital music signal for the
high-precision Cirrus Logic digital-to-analog converters. Once in
the analog domain, music signals flow through Marantz proprietary
HDAM-SA2 modules rather than conventional opamps for
exceptionally smooth stage-to-stage transition. Other circuit
elements were chosen and combined only after careful
comparative listening revealed their superior audio performance.
Symmetrical signal traces eliminate channel-to-channel time delay
for pinpoint imaging while machined output jacks mounted on a
Zero-Impedance copper plate provide connection to the rest of
your system.
In further homage to the Marantz tradition, the SA-KI Pearl SA-CD
player also includes a number of conveniences. You can use the
internal converters to process non-disc digital sources such as an
iPod or MP3 player. The digital output is individually shielded to
minimize interference. And a current-buffer headphone amplifier
provides extraordinary private listening. As a final touch, the
SA-KI Pearl handles CDs of all types – conventional, MP3-, or
WMA-encoded discs as well as two-channel SA-CDs.
This Pearl will satisfy the most critical listener. And the most
demanding décor-conscious music aficionado. Part engineering
and part instinctive understanding of music’s demands, the
SA-KI Pearl disc player is the culmination of the Marantz
tradition and Ken Ishiwata’s demanding ear.
