[-----=F-=E=-=----=AT~U=____R_E_S
] I
This unit was developed with many of the same functions as
the flagship model SC-7S2, without compromising the sound
quality.
• 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 current-voltage
converter and input buffer.
• Constant Current Feedback Phono
Equalizer
The new phono equalizer keeps current feedback constant
from low to high frequency, and supports both MC and MM
cartridges. This has enabled problems
in
sound quality found
in
conventional NFB type phono equalizers that resulted from
differences
in
the amount of NFB
in
the bass and treble regions
to be
overcome.
• Choke Input Power Circuit
This unit incorporates a choke input power circuit
in
order
to
thoroughly eliminate high frequency noise from the rectifier
circuit and external sources. The choke input power supply
is
a powerful, clean power circuit that stores electrical power
in
the coil and capacitor, and then supplies it to the amplifier
circuit.
• Tone Control
This unit
is
equipped with
an
electronictone control circuit that
adjusts the sound balance using the remote control unit. This
tone control circuit can be precisely adjusted with the Balance
Linear Control Volume.
• Subsonic Filter
Subsonic signals are intercepted
in
the cut-off frequency 15Hz
(12dB/oct) by the subsonic filter. The subsonic filter
is
an active
filter used
in
the HDAM-SA3.
• Balanced Linear Control Volume
The newly developed balanced output type volume control
amplifier incorporates a combination of the WM8816 by
Wolfson with the Marantz original current-feedback amplifier.
This balanced linear control amplifier
is
a high performance
amplifier that allow to control the sound volume and to
convert
the balance signal.
• Balanced Input Headphone System
This
is
a balanced inputcurrent feedback headphone amplifier
newly developed for use with the Balanced Linear Control
Volume. This power amplifier is special combination of a
high quality sound operational amplifier and discrete current-
feedback type amplifier specifically for headphone use.
• Input Buffer
With the exception of the PHONO input, each input has its
own input buffer that directly uses HDAM-SA3 technology.
You
will experience superb sound with unbelievable channel
separation.
• F.C.B.S,
A Floating Control Bus System (EC.B.S.) enables the user
to
connect
up
to
four units, making a diversity of applications
possible with bi-amp and multi-channel connections.
Moreover,
a ground loop is not formed between multiple connected
amplifiers, therefore sound quality
is
not adversely affected.
• BI-AMP Mode
The operating mode that uses the complete bi-amp connection
proposed
by
Marantz. Complete bi-amp allows two
SC-11
S1
to
be
connected
by
EC.B.S. enabling each to work as a monaural
Integrated amplifier.
• Display
This unit adopts
an
LCD (Liquid Crystal Display)
to
display input
source and volume
level. Compared to other types of display
panels,
an
LCD generates less drive noise and radiation noise,
hence the interference
in
sound quality
is
minimal.
• Remote Power Control
3
This unit is equipped with a trigger output jack that can
simultaneously operate the power ON/OFF control of a Marantz
SM-11 S1 power amplifier
in
sync with the power ON/OFF
control of this unit. Up to two SM-11
S1
can be connected to
this unit. As with the EC.B.S. a ground floating connection is
made without a ground loop being formed, therefore sound
quality
is
not adversely affected.
