Extendable high-end power
Designed to make the perfect match with the PM-17mkII'M'
and PM-17mkII'M' KI, the SM-17 is the perfect solution for
the ones who are looking for a solid power amplifier with the
best musical performance. The SM-17 can be switched into
BTL-mode to increase the power dramatically. Multiple SM-17's
can be used in the total set-up to form the ultimate power
amplifier combination for your loudspeakers, even when they
are difficult to drive.
Current Feedback amplification
Unlike conventional voltage feed back amplification, the
Current Feedback amplification makes the power amplifier in-
sensitive to difficult loudspeaker loads.
BTL switch mode
Marantz designs their amplifiers to have robust power outputs.
For the very demanding listener Marantz offers the ability to
extent with separate stereo power amplifiers. These amplifiers
can be used in BTL mode. When operating in BTL, the
amplifiers operates as a mono amplifier with more then twice
the power rating. By offering the normal mono signal to the left
channel and the inverted signal to the right channel of the
power amplifier, the difference signal represents the amplified
monaural signal.
HDAM
Only the best is good enough! In order to use equipment from
several brands together in one system, the audio industry made a
signal pre-out standard. To convert the audio signal to this
specification, every
audio device has been
equipped with Op-
amps (operational
amplifiers) for which
integrated circuit are
commonly used.
Unfortunately these
IC's do not match the
very high requirements
of Marantz. Marantz
developed it's own discrete circuit boards. These HDAM's
consists of discrete surface mount components with short mirror
image L/R signal paths. These devices are doing exactly the samething as the Op-amps, but outperform the regular integrated
circuit Op-amps dramatically in terms of the Slew Rate,
resulting in a much more dynamic, accurate and detailed sound.
WBT terminals
WBT is a specialised company which is fully dedicated towards
designing and producing high quality audio connectors.
Their products are fully accepted as the reference for audiophile
products. For this
reason Marantz equips
our premium products
with WBT connectors.
Super Ring transformer
Super-Ring transformer has the same advantage with a toroidal
transformer such as high efficiency, stability, and speed. In
addition to that the super ring transformer outperform the
toroidal transformer on certain
aspects. Thanks to its round shape of
the core, the super ring transformer's
electro-magnetic radiation and
mechanical vibration are extremely
low.
CCNE
Continued research has revealed a new area of refinement: the
power supply noise. Marantz has developed the Current
Conversion Noise Elimination (CCNE), which improves the
mid-band to high frequency signals, through a clear elimination
of high frequency distortion in the amplifier output. This offers
the listener a sweeter sound with improved high frequency
definition.

Linear Drive Power Supply (LDPS)
Marantz' Linear Drive Power Supply (LDPS) makes sure that
there will always be enough power available to drive the speakers
even with the very highest dynamics. The LDPS also enables the
amplifier to drive difficult speaker loads.
