POWER ON/OFF
This unit was developed with many of the same functions as
the flagship model MA-9S2 and with a 2-channel function,
without compromising the sound quality.
¶ Improved Instantaneous Current Delivery
Capacity
The final stage of the power buffer amp has a LAPT special
power transistor parallel push-pull construction to improve
delivery, and the block capacitor and power buffer amplifier
are unified.
Also, the block capacitor and unified power buffer enable the
reduction of the current loop path, creating superior channel
separation.
¶ HDAM-SA3
The HDAM-SA3 is an amp module equipped with a new circuit
that has further improved stability from the previous HDAM-SA
and HDAM-SA2.
The HDAM-SA3 is an essential part of this unit’s amp module,
incorporated into many components such as the voltage-
current converter and input buffer.
¶ Input Buffer
Each input has its own input buffer that directly uses HDAM-
SA3 technology to prevent interference between channels or
input sources.
¶ Dual Structure Voltage Amplifier
+ Power Buffer Amplifier
Speakers with powerful magnetic circuits have large back
electromotive force, and are therefore not easy to drive.
Therefore, in the same way as the MA-9S2, this unit was
developed with the dual structure of a voltage amplifier and
power buffer amplifier so that there is no influence from the
back electromagnetic force.
¶ BALANCED/UNBALANCED Individual Gain
Setting Function
The gain can be set individually for BALANCED input and
UNBALANCED input according to the intended use.
¶ Digital Power Meter
¶ Differential Input Voltage Amplifier
The actual output power can be indicated on the display by
detecting the speaker output voltage and output current.
Considering overall sound quality, a PLD (programmable logic
device) is used instead of DSP for the digital processing to
minimize the amount of digital noise.
The current feedback voltage amplifier that is equipped with
the newly developed HDAM-SA3 and features differential
input amplifies the voltage of the balanced input signals and
unbalanced input signals.
Furthermore, it can also be switched between gain conversion
or stereo mode to BTL monaural mode.
¶ Remote Power Control
The Power to this unit can be switched ON/OFF in sync with
the Marantz SC-11S1 stereo control amplifier ON/OFF control
using the remote power control function.
¶
New Current Feedback Power Buffer Amplifier
The power buffer amplifier that powerfully drives the speakers
incorporates a voltage-current conversion circuit that contains
a newly developed Complimentary Cascade Push-pull Circuit,
which greatly increases stability.
The connection with the SC-11S1 is made without a ground
loop being formed, therefore sound quality is not adversely
affected.
Furthermore, the combination of the Wilson current mirror
circuit and Cascade bootstrap circuit in the current amplification
circuit provides power amplification with low distortion in the
super-high frequency.

7 Connection Example 2: Upgraded version of connection example 1 using bi-wiring
connections
Use bi-wiring connections to connect the unit and speaker system with 2 sets of speaker cables.
Before connecting the speaker system using bi-wiring, check to make sure that the speaker system supports bi-wiring.
¶ Bi-Wiring Connection
Bi-wiring connection is a technique for improving sound quality by separately connecting the low and mid/high jacks of the speaker
to the amplifier using separate cables.
By using separate cables for low and mid/high sounds, the return current generated in the low speaker causes little interference
with the mid/high speaker.

7 Connection Example 4: Stereo Complete Bi-amp Connection
1. Connect 2 Marantz SC-11S1 by F.C.B.S. for synchronized control.
For F.C.B.S. connection, connect with commercially available cables with monaural ⇔ monaural miniplugs or stereo ⇔ stereo
miniplugs as described in F.C.B.S. (pg. 26) in the SC-11S1 instruction manual.
2. Refer to the SC-11S1 instruction manual (pg. 27) and set the SC-11S1 ID numbers.
3. Connect the analog output of the CD player etc. to the L ch input jacks of both pre-amps. As both pre-amps operate as monaural
pre-amps in BI-AMP mode, do not use the R channel of the input jacks for the SC-11S1.
¶ About Complete Bi-Amp
Proposed by Marantz, the complete bi-amp connection is an advanced technique that enhances sound quality.The low and mid/high
amplifiers are separate and independent of the preamplifier, therefore interference between low and mid/high sounds is reduced
to a minimum. As a result, a wide sound environment can be reproduced.
Note:
Speaker systems that can be connected using complete bi-amp must support bi-amp connections. Before connecting your
speaker system, check the speaker system instruction manual, or contact the speaker manufacturer to check whether the
speakers support bi-amp connections.

SPEAKER POSITIONING FOR SUPER
AUDIO MULTI-CHANNEL SOUND
CONNECTING THE POWER SUPPLY
1. Plug the power cable into AC IN jack on the back panel.
In order to enjoy Super Audio CD multi-channel sound with
the best possible acoustics, it is recommended to position
speakers as specified in ITU-R BS.775-1 of the International
Telecommunication Union (ITU).Super Audio CD multi-channel
discs are recorded and mixed so as to achieve the optimum
effect with a speaker system laid out as specified in ITU-R
BS.775-1.
• With Super Audio CD multi-channel discs, the music signals
are basically recorded using 5 channels (3 - 6 channels
sometimes), but in some cases, LFE (for subwoofer) is
recorded as a sixth channel. Each disc indicates how many
channels have been recorded on it.
• The basic layout is 3 speakers in the front and 2 in the back
since multi-channel discs usually have 5 channels. The 2
front, 1 center and 2 surround (rear) speakers should be set
in a circle around the listening point as shown below.If using
speakers of differing sizes, adjust volume balance from the
amplifier.
2. Turn on the power switch of the audio unit (amplifier, etc.)
that is connected with this unit. Set the selector on the
connected unit to this unit.
3. Plug the power cable into an AC outlet.
• The location of the subwoofer in the figure is just for
explanatory purposes. It can be located anywhere in the
room. For connection and positioning instructions, see the
instruction manual that came with the subwoofer.

TROUBLESHOOTING
If you experience trouble with the SM-11S1, make the below
checks before thinking the worst. Improper operation can
cause the SM-11S1 to behave in a way that makes you think
something is wrong with the equipment when actually not. If
the trouble cannot be fixed after making the below checks,
contact the place of purchase, your nearest Marantz dealer,
our customer service center or our repair service center.
7 Protective Circuits
This unit is equipped with protective circuits to protect the
amplifier circuits and speaker system against damage. If a
protective circuit trips, the sound is instantly muted. In this
case, “PROTECT” flashes on the display and the STANDBY
indicator also flashes.
¶ At Power ON
¶ Power does not turn ON
For about 8 seconds after power is activated, a protective
circuit trips and mutes the sound to give amplifier circuits time
to stabilize. Once the amplifier circuits stabilize, the protective
circuit releases and audio is enabled.
1. Is the power cable securely plugged into a power outlet?
2. Is the remote power control switch on the rear panel set
correctly?
¶ Nothing is heard from the speakers
¶ In the Event of Over current
A protective circuit trips if current that exceeds the set level is
detected, which can happen if excessive signal flow is input to
the amplifier, or if the unit is connected to a speaker system of
less than 4Ω impedance. A protective circuit can also trip if a
speaker cable accidentally shorts.In these cases, “PROTECT”
flashes on the display, and the STANDBY indicator flashes red.
To release the protective circuits, switch the power OFF, and
wait for approximately 1 minute before switching the power
back ON again.
1. Is the SPEAKERS button on the front panel OFF?
2. Is the input set correctly using the BALANCED button or
UNBALANCED button on the front panel?
3. Is the gain switching mode in use causing sound to be
muted?
4. Are connection cables and speaker cables securely
connected?
5. A protective circuit may have tripped causing sound to
be muted. If PROTECT is flashing in the display, switch
the power off and wait for approximately 1 minute before
switching the power on again.
¶ If Strong Bass Signals Are Input
A protective circuit trips if bass signals of an excessive level
are detected.
¶ Sound from the speakers is not stereo
In these cases, “PROTECT” flashes on the display, and the
STANDBY indicator flashes red. To release the protective
circuits, switch the power OFF, and wait for approximately 1
minute before switching the power back ON again.
The MODE switch on the rear panel may be set to BTL. If the
switch is set to BTL, switch off the power, change the AMP
MODE switch to STEREO, and then switch the unit’s power
back on again.
¶ If the Amplifier Overheats
A protective circuit trips if the temperature of the main amplifier
rises above the set level, which can happen if excessive signal
flow is continually input into the amplifier. Temperature can
also exceed the trip level of the protective circuits if the vents
on the top of the unit are covered, or if the unit is installed on
a cramped audio rack. In these cases, “PROTECT” flashes
on the display, and the STANDBY indicator flashes red. To
release the protective circuit, switch off the power supply and
wait for the amplifier to cool to operational temperature before
switching the power on again.
¶ In the Event of Amplifier Trouble
A protective circuit trips and automatically shuts off the power
if an abnormality is detected in the power circuit for whatever
reason.The same happens if the main fuse inside the amplifier
blows. In these cases, the STANDBY indicator on the display
flashes red.
Switch off the power supply, and wait for a few minutes before
switching the power on again. If the display does not light and
the STANDBY indicator continues to flash after switching the
power on again, the unit has a fault.
