FEATURES
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.
¶
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 input current 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.
¶
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 electronic tone 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.
¶
F.C.B.S.
A Floating Control Bus System (F.C.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-11S1 to
be connected by F.C.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
This unit is equipped with a trigger output jack that can
simultaneously operate the power ON/OFF control of a Marantz
SM-11S1 power amplifier in sync with the power ON/OFF
control of this unit. Up to two SM-11S1 can be connected to
this unit. As with the F.C.B.S. a ground floating connection is
made without a ground loop being formed, therefore sound
quality is not adversely affected.
