places
To ensure long-lasting use, do not locate the unit
where:
• Exposed to direct sunlight.
• Near to sources of heat such as heaters.
• Highly humid or poorly ventilated.
• Dusty.
• Subjected to mechanical vibrations.
• On wobbly, inclin
ed or otherwise unstable
su
rfaces.
• Radiated heat is blocked such as in cramped
audio racks.
To ensure proper heat radiation, ensure the below
clearance from walls and other equipment.

cause burns.
Features
all-discrete curreNt-FeedBacK
ampliFier
Marantz
’
proprietary current-feedback circuit, using
discrete components, is adopted in the pre amplifier
and power amplifier. It is a high-speed amplifier
using the latest technology developed for the
higher-grade amplifiers.
hdam-sa3 techNologY
The V/I converter circuit, which is the key block
of the current-feedback pre-amplifier and power
amplifier, is equivalen
t to the HDAM-SA3 amp-
module developed for such higher-grade models as
the SC-11S1.
cd direct BuFFer ampliFier
An input buffer amplifier exclusive for CD is mounted
near the CD input jacks. This is a high-speed buffer
amplifier made with discrete components, which
avoids interference between right and left channels
and can send the signals to the pre-amplifier with
very high fidelity.
improVed momeNtarY curreNt
supplY aBilitY
It is generally known that the sound quality is not
necessarily the same even if amplifiers have the
same specifications. Marantz considers the cause
to be the power to drive speakers. The power
amplifier of this unit has the ability to momentarily
supply current of 25 A or more to drive speakers
strongly.
short-poWer-liNe laYout
For strong momentary current supply, a short
power-
line layout unifies the power circuit and
o
u
tput stage of the power amplifier section. This
layout allows connecting the large-current lines via
the shortest route while to arranging the left and
right channels symmetrically.
all-discrete curreNt-FeedBacK
phoNo eQualiZer
As a phono equalizer amplifier for MM cartridges,
a constant current-feedback PHONO equalizer of
quality equal to that of the higher-grade model SC-
11S1 is used.
douBle-shielded toroidal
traNsFormer
The unit is equipped with a toroidal power
transformer to minimize vibration and leakage flux
specific to the transformer. Especially to reduce
leakage flux, w
hich affects sound quality, the
p
e
riphery is double-shielded, using a core ring and
a short ring.
BlocK coNdeNser oF large capacitY
A large-capacity condenser of 18,000 F is used in
the power circuit of the power amplifier. In the pre-
amplifier, a 4,700 F condenser is used.
