Marantz SA-11S2 Reference Series 2010 Catalog - Page 14

SA-7S1 Stereo Super Audio CD Player Although most people think of the Marantz heritage as one based on preamplifiers and power amplifiers, Marantz was the first company in the world to announce a Compact Disc player! Since that groundbreaking event, Marantz has led the way in offering advanced digital playback with an unwavering focus on sound quality. The SA-7S1, unabashedly designed for the finest two-channel music reproduction possible, continues that tradition. Capable of playing CDs, CD-Rs, CD-RWs, and stereo Super Audio CDs, the SA-7S1 combines several significant technical accomplishments to advance your musical enjoyment. As are other Reference products, the SA-7S1's circuitry is housed in a double-layer, copper shielded chassis for dimensional stability and thorough isolation from external interferences. The power supply includes a high-capacity toroidal transformer entirely shielded by a silicon steel plate and a copper-plated case. This keeps magnetic radiation from affecting internal circuitry. The disc transport itself is a Marantz-designed example of exceptional metal crafting. The mechanism sits in a case of extruded aluminum while the disc drawer is cast to exacting tolerances. Servo and signal processing circuits are situated on a four layer glass epoxy board mounted close to the transport. A Marantz-developed digital filter/noise shaper with user-selectable characteristics (including digital phase inversion) operates on new proprietary algorithms. Independent D/A converters process either PCM information from a CD or DSD data streams from Super Audio CDs. A high-accuracy master clock insures precise timing for extreme clarity. A unique Digital Isolator completely separates ground connections between digital and analog circuitry for optimal isolation. After this, two D/A converters, each composed of four separate processors, provide 24-bit resolution for both PCM and DSD signals. Analog circuitry follows the Marantz maxim of proven quality enhanced with the best contemporary technology. Fully balanced circuits benefit from multiple Hyper Dynamic Amplifier Module (HDAM®) modules in critical sections. The output buffer amps are HDAM SA2, chosen for their outstanding speed and timbral accuracy. Aesthetically, the SA-7S1 evidences the typical care that has always distinguished Marantz products. The clean yet functional design is another manifestation of our desire to meld sound quality and superior appearance. The SA-7S1 is indeed a Reference. And indeed a Marantz.
