SC-7S2 Stereo Control Amplifier A singular integration of performance, functionality, and design, the SC-7S2 thoroughly updates the concept of a stereo preamplifier. Although it traces its sonic heritage to the distinctive voice of the original Marantz Model 7, the SC-7S2 is not tied to even the best of past technology. A significant improvement over the acclaimed SC-7S1, the S2 version incorporates a full roster of technical refinements to enhance your perception of even the most complex musical compositions. Simultaneously, the SC-7S2 avoids any aura of techno-intimidation. Instead of an often confusing array of knobs and switches, it spaces Input Select, Power, and Volume across a finely-finished champagne front panel. An aluminum-topped remote control adds critical but lessoften-used functions such as input trim and display intensity to tailor the SC-7S2 to your preferences. In its quest for musical accuracy, Marantz gifted the SC-7S2 with refinements that define advanced audio circuitry. These include a sophisticated power supply based on a toroidal transformer for reduced spurious noise. Further refinements contribute to the SC-7S2's extraordinary frequency response and channel separation. Isolated inputs eliminate unwanted interactions. All signal paths, including the critical volume control section, are fully balanced to minimize noise. In fact, the volume control benefits from multiple microprocessors that eliminate distracting clicks when changing volume settings. Together, the microprocessors and an array of HDAM modules form an incredibly precise attenuation circuit with easily repeatable 0.5 dB steps throughout its entire range to insure proper channel balance at any listening level. Of even greater importance is the inclusion of the SA version of Marantz's proprietary HDAM® (Hyper Dynamic Amplifier Module) circuitry. These modules insure accurate and distortion-free audio signal transfer from one stage to the next. Although the SC-7S2 is devoutly two-channel, it acknowledges the multi-channel world with our Floating Control Bus System (F.C.B.S.) that lets you control multiple SC-7S2s simultaneously for full Reference-level performance. A copper-plated aluminum chassis with a double layered bottom plate, provides exceptional stability as well as isolation from external noise sources. The SC-7S2 Control Amplifier is an enduring testament to the synergy of today's technologies, meticulous implementation, and exquisite cosmetic design. It is a reference in every sense of the word. "Good design is a renaissance attitude that combines technology, cognitive science, human need, and beauty to produce something that the 4 world didn't know it was missing." - Paola Antonelli, Architect and Museum Curator At the heart of audio perfection...
